3 - Dry stack concrete block walls use surface bonding cement (SBC) for additional structural strength - no mortar between cinder blocks. Click here for the main chapter of our free HTM Passive Solar Design eBook

Dry stack concrete block (cinder block) technique uses surface bonding cement (SBC) instead of mortar for high thermal mass walls that are actually stronger than conventionally laid block walls. Only the first course is bedded in grout on the footer to establish plumb and level for the wall. The rest of the dry stack block courses are laid without need for any mortar between the cinder blocks. This building method has been around for well over a century, so it is nothing new or really even very unique in commercial buildings. SBC was formulated to build million gallon municipal cisterns for water storage. The original SBC recipe used horse hair for the structural fibers. There is absolutely no need for special 'dry stack blocks', but they are available in some areas of the country. Typical rectangular concrete blocks are fine as long as the quality is good. And the quality is almost always very good these days with computerized forming and automated molding of concrete blocks at most brick yards. Plus, you will likely be buying a locally made product since block manufacturing yards are to be found in nearly every part of the country.

Build cinder block walls without mortar between the block and just a few tools

Blocks need not be of any special design. They don't have to interlock, and best of all you don't have to know how to lay block. You simply stack the concrete blocks in a running bond pattern and then parge coat both sides with a single layer of fiber reinforced, surface bonding cement. Applied 1/8 inch thick minimum to both sides, surface bonding cements have strengths that are superior to conventionally mortared block walls and they look a lot better too without any grout lines. Once your block walls have been surface bonded, hollow vertical cores (minimum every four foot and alongside every opening) are filled with ready-mix concrete grout and a #5 rebar for an exceptionally strong heat storage mass. Mortared block walls are just as effective, but dry stack is easier for the unskilled homeowner builder. You don't need any experience laying block to excel at dry stack with SBC.

First course of cinder block is laid upon a bed of mortar on the concrete footers. Concrete block is then perfectly leveled, as this is the start of building without mortar between courses

Please note that solid, poured in place, concrete walls are just as effective, but forming and pouring is outside the skill level of most people. Hiring contractors to build the forms, pour the walls and then return to strip the forms, is always an option when you have money in the budget. Empty cores in your block walls (those not having structural rebar) should be filled with something for extra thermal mass. There is no advantage to having empty cores in the block walls and absolutely no advantage to filling them with insulation. The more thermal mass in a home, the better. Most clients simply order more concrete grout and fill the empty cores while they fill the structural cores, but some clients opt for using sand or dirt excavated from the job site. The only caveats to using soil to fill the empty block cores is to compact well and cap the top of the core with SBC or mortar to prevent moisture from penetrating.

Very easy to set, dry stack concrete block walls do not need any mortar between blocks and courses

One key to thermal performance and indoor air quality is to have waterproof walls to guard against moisture transference and surface bonding cement was originally designed to line water cistern tanks. You need to prevent water from traveling through the home's walls, sucking away energy and presenting possible indoor air quality problems. The same applies to poured-in-place concrete walls - the wall needs to be waterproofed on both sides to prevent water transfer. Several coats of low VOC non-porous latex paint is a good solution for waterproofing the interior of a concrete wall. The exterior footers and wall need a minimum of two heavy coats mop-on waterproofing treatment or better yet, a roll roofing underlayment sheet bithumin, like Grace® Ice and Water Shield.

Layer surface bonding cement onto both blocks and then lower into place for a tight fit Check your plumb (vertical level) often to avoid getting off track with a wall

Surface bonding cement is both the structural coating and interior finish stucco SBC can be applied in stages, just leave off at middle of block for best strength

Dry stack concrete block walls using surface bonding cement instead of mortar are easy to build without special skills.

Water and waste lines are best run through stick-frame partition 'wet walls' in the floorplan layout, but pipe can be run through the block wall cores, if need be. Wiring in concrete block or poured-in-place concrete walls usually involves running conduit pipe down through the cinder block cores or forms before the pour and then pulling wire later to all the outlet and switch boxes. In-floor electrical outlets like you see in commercial buildings are an option for electrical, as are surface mounted Wire-Mold® power strips. One of the more visually pleasing and labor-saving ways to run some wiring is shown here with half-round logs routered out along the back and holes cut for outlet and switch boxes. Nice design touch that does not require that much carpentry skill.

With any surface bonding cement, conventional mortared block, or poured-in-place cement wall, it is key to note:
* do not fill block cores with insulation or foam. This is counter to what you are trying to achieve. The empty cores should be filled with concrete, sand or some other solid thermal mass material.
* vibrate the newly poured wall cores thoroughly to avoid air pockets. These tools are relatively inexpensive from companies like Harbor Freight Tools. Removing air pockets from structural concrete filled cores is very important for ultimate wall strength.
* interior walls are surface bonded, so there is no need to stucco or drywall. You can do a finish coat of stucco to attain a particular texture, though, or use a synthetic stucco mixture.
* always coat the exterior and interior of your walls with waterproofing. Water absorption and transference must be stopped to maintain interior air quality. A high quality non-porous latex does wonders.
* exterior insulation on the walls must be surface bonded with a latex modifier added to allow it to stick to the EPS foam. Reinforce with galvanized chicken wire or expanded lathe for structural integrity.

If you are not familiar with laying block (mortared or surface bonded), after the corners are stacked six to eight rows high, setting the string line is critical. The corners dictate the walls between. Starting from corners, you simply stack block between. You can alternate last blocks, but it is generally the center block and it rarely needs shaved to fit. There are probably as many different ways to knot the line block as there are masons. Xing at the knuckle (full corner end of wooden line block) certainly helps stabilize or you can just wrap the string once or twice around block lengthwise, then anchor back to pin. You can pull in slack a lot easier this way, cinching to line pin, plus it ensures the string line will remain taut and true. While it is possible to simply set the wood line block on corner and tie off with tension alone, having an anchor post pin as shown is a little more elegant and saves the string from being subject to possibly jumping off.

Wood line block and line pins as used with dry stack concrete or cinder block construction to get a straight wall

As with most everything in life, there are at least two opinions on the correct usage of the string line (mason line). Most prefer to keep string line a set distance from block (5/8 inch as pictured above with the Marshalltown® line block). This allows you to use your fingers as a quick spacer - as soon as fingers touch line, you know you are about true for stacking. Classic masonry with grouted courses, forces you to hold the block at center pull / cavity opening (fingers inside block to steady and drop plumb). You can't always be looking down on the block, though, and you really don't need to with dry stack. Some masons like the string line right where the blocks are going. You just have to maintain clearance, even if only 1/16 inch, to keep true. Nothing should ever touch the string line or it is compromised. It is possible to keep the wall plumb (vertical) and level (horizontal) without a string line reference, but the only way to keep it straight (true) is with a string line. Wander 1/16 inch off true every coarse and you will find the wall with a 1/2 inch error before you know it.

The beauty of dry stack SBC versus mortar block is not having to make sure each and every block is plumb, level and true before setting the next block. When you are rolling along with stacking the block, you never stop to check every single block... you lay the course just shy of stringline true and then come back to adjust all the blocks over to the line. A large rubber mallet does a quick and efficient job of trueing the wall until you get two or three courses atop the errant block. This is where you notice the great strength provided by friction with six blocks touching the one you want to move and gravity at play. After the surface bonding cement is applied and structural cores filled, a SBC block wall is actually much stronger than a comparable mortared block wall

A major time saver is to never cut any blocks for the layout so you should always design around using all full and half blocks. The block layout we normally work with is eight inch wide block (8" wide, 15.625" long, and 7.625" tall). Maintaining a running bond stack where the upper block overlaps half of lower block is easy with eight inch wide since the corner turns on 1/2 of the width (15.625 inch long and eight inch wide). When the design requires changing to 12 inch wide block (berming into a hillside) you suddenly need to cut a block every other course. The first course is traditionally all full blocks (12 inch by 15.625 inch long). The second course (as shown below) uses a cut block - one 4 inch and the other what is left over (about 11-1/4" to 11-1/2" long). Half blocks are only used at the end of a wall or doorway opening, never in a corner or on a straight wall run between two corners.

Dry stack concrete or cinder block layout with 12 inch wide CMUs

One key to SBC or any other Portland® cement based stucco, concrete or mortar is to keep the finished material moist for the first few days of curing. Any cement based product needs to cure slow and steady for optimal full-strength and that can take up to a month for a concrete slab. If you want a quality product, get several hand pump sprayers for misting water during construction. Tent and heat the first course with mortar bed and keep it moist for the first few days of set, especially when temperatures are going to dip below 50 degrees. The same applies to any SBC work later. When dry stacking or mortar block laying in a cold climate, you should consider covering the entire structure with string reinforced poly sheeting. The tops of block walls can be spanned with a few beams and clear tarp material draped across all walls. Common roll size is 20' by 100', with 40' by 100' available in some areas. There is also a woven mat material. Commercial projects often leave the plastic tent in place for the entire construction, cutting away with razor knives after the ceiling has been oiled and interior is ready to work. Then the clear tarp just falls to the floor and becomes a drop cloth to keep traffic off concrete.

You can purchase surface bonding material at any building supply center or at wholesale by the pallet from your block yard. We do not sell it and we are not the manufacturer. Our only interest in proposing SBC as a building method is to help our clients save some money while having the ability to construct their own home with their own hands. For an introduction to common dry stack cinder block construction techniques, please take this link: Quikrete® basic SBC Project Guide. This Quikwall manual is helpful for do-it-yourselfers considering a surface bonding cement project. The Quikrete manufacturer website for SBC is or you can call their help line at 800-282-5828. Please note many other surface bonding cement manufacturers exist - check with your local block yard for details.

We have always delighted when new professionals become familiar with dry stack cinder block techniques. Cinder block has been a popular commercial building material for ages, but wood has always ruled for residential here in the USA. That's what makes an HTM so economical and functionally sensible - this common commercial style of block or poured-in-place concrete construction. HTM design just adds a coat of surface bonding cement to stop water transference and horizontal wing insulation for heating and cooling retention. Concrete and block are very low-tech LOCALLY available products without all the marketing fluff associated with SIPS, ICF pre-packaged insulated forms, special block shapes, and other trick methods. Reinventing the wheel is not necessary... any local commercial contractor should be more than capable of working on the project. Here's hoping more websites, architects, engineers, and building departments get familiar with a worthy method. For a technique that has been around for centuries, it gets entirely too little attention.

Top left going clockwise: darby, pool float, bucket scoop, arch rasper, and mortar hawk are common tools for use with SBC

We do not sell any tools, but darbies, pool floats, magnesium hawks, arch raspers and bucket scoops can be found locally at construction tool suppliers. The same tools used for stucco work are used for surface bonding and parge coating of dry stack cinder block. The pool float is a hockey rink shaped applicator preferred by many to work the stucco or SBC into place. A foam handle is nice, if you keep your tools clean. Otherwise, composite handles are much easier to maintain. Magnesium blades are preferred by many for their ability to 'open pores' in the cement, versus sealing smooth and tight, as with steel blades. Magnesium has a nice feel, being rust proof and lightweight, yet thick and strong, making it preferred for hawks, floats and darbies. Arch rasps and bucket scoops are the other two images above - specialized tools for unique needs can cut labor time dramatically. The darby, for instance, is a two to four foot long two handed leveler that makes it possible to flat-level large surfaces quickly. Some darbies come with teeth for a sawing action as you level across the wall or floor. Others are flat with rounded lips along edge for sawing, smoothing and leveling more gently at the stucco, plaster or SBC.

Dry stacking is addressed on our website as a courtesy to our HTM clients interested in alternative high thermal mass wall construction techniques and not something we specialize in. Legal liability dictates engineering details are site-specific and dependent upon site and soil conditions, local building code, and the floor, wall, and roof construction methods. If the manufacturer of surface bonding cement being used is not able to provide construction advice for their product, it is best practice to hire a local structural engineer. Unfortunately, we are not able to provide such services. There are some businesses on the internet that specialize in dry stacking, for instance from our research links page is the website

Surface bonding cement SBC dry stack concrete masonry unit CMU block wall and monolithic foundation details are typical and common to any size building, but will naturally vary depending upon size of structure, soil and site conditions, and local building codes requirements. Conservative engineering practice is to design SBC wall reinforcement (rebar) in the same grid pattern as a mortared block wall, given site, soil, and foundation variables. In high thermal mass construction, it is standard practice to fill all cores. No hollow cores in an HTM. Non-structural cores can be filled with sand or similar. But in practice, if you are 'shooting cores' with a pumper truck, it is sensible to just go ahead and pour all cores with concrete 'grout' while you have the machinery on site. We no longer provide construction, consultation, or engineering services and any information presented on this website is for 'entertainment purposes only'. Site, soil, and local code requirements are only the first of many unknown variables. We do not warrant information for any errors or omissions. Plans are not presented as construction ready. Local engineering approval must always be obtained first, before building. Click on drawing for printable Adobe .pdf file. Best wishes for your project.

The roof structure, cmu rebar pattern, and backfill depth dictate ultimate wall engineering design. While possible to avoid interior perpendicular walls and counterforts entirely, it is common practice to have one every ~18 foot when the roof structure does not provide adequate stability. Placed perpendicular, roof beams act as retaining. Placed in other direction (parallel with wall) roof beams provide no wall support. Then the interior perpendicular walls both retain and provide bearing for parallel roof beams. Thus the ~18 foot mark for allowing 20 foot beams to span. Using roof trusses instead of beams has much the same, but lesser retaining effect, but only when opposite wall provides anchor for far end of truss. Sometimes you see short 'stub' block walls (counterforts) used to retain, with wood frame walls extended past counterforts on interior. Boils down to whether exterior wall is retaining backfill against structure.

Free 48 State Delivery

All shopping cart items are advertised as Free Shipping with no extra charge for delivery. Shipping and handling fees are factored into advertised total delivered price. Note shipping is only available to the 48 contiguous United States of America. We do not ship into Canada or Mexico, Puerto Rico, Alaska, Hawaii, Virgin Isles, APO/FPO mailboxes, or any off-shore or international destination. Inventory 'stock' items will ship within 2-3 business days from one of Our warehouses. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date. Motor freight deliveries do not include lift gate service to lower boxes onto the roadway, unless quoted with additional services. If need be, lift gate service to lower boxes onto roadway is available for an additional $65 to $100 fee. Street-side motor freight deliveries are not brought to your front door by the driver, like UPS and Fed-Ex package services. Client must meet motor freight truck deliveries on the street to unload and inspect shipments by hand before signing for Merchandise. Shipments must be accepted promptly within three days of arrival at local freight terminal or storage fees of +/- $50 per day, per pallet may apply. Any and all storage fees billed by trucking company are the sole responsibility of Client and must be reimbursed to Our company.

Fed-Ex and UPS Ground

Most shopping cart items ship via Fed-Ex or UPS Ground package delivery service. Package delivery services, unlike a motor freight carrier (see next paragraph), will allow us to file a hidden damage in transit claim for insurance reimbursement, but We are given less than a week to report it. Regardless of how well the exterior of container box appears, you must ALWAYS have the driver note ANY damage to shipping boxes in writing before signing. Then immediately, always take Merchandise completely out of its packaging and inspect ALL of the Merchandise, notifying us immediately should there be ANY hidden damage to Merchandise. Mechanical problems are covered under the manufacturer warranty, but hidden aesthetic damages (cosmetic dings, dents, broken Welds, significant scratches, or popped rivets) you discover than a week after delivery are not reimbursed or replaced by Fed-EX, manufacturer, Kobe, or Not saying that you or your Merchant caused the damage to the unit before or during installation, but that possibility exists when Merchandise is not properly inspected upon arrival. Additionally, any appearance (non-mechanical) flaws found after installation will not be reimbursed or replaced by freight carrier, Fed-EX, manufacturer, Kobe, or Merchandise that has been installed is not eligible for return or replacement by

Motor Freight Shipping

Servel refrigerators, Sun-Mar composters, larger custom shade panels and larger Kobe range hoods ship via motor freight 'common carrier', as noted on the website and receipt. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date.Common carrier motor freight is shipped on a pallet with boxes covered in clear plastic stretch-wrap and is defined as street-side motor freight drop, which differs from small package services like UPS and Fed-Ex, in that the truck driver does not bring Merchandise into your building or onto the porch. Street-side motor freight drop is a basic delivery service, often in a full-size tractor trailer, where driver parks in street while you unload and inspect the Merchandise. Kobe range hoods, shade panels, and Sun-Mar composters are not shipped with lift-gate service. You must unload boxes from the tractor trailer by hand. If you require lift gate service to lower the Kobe range hood down onto the roadway, with what they call a mechanical 'Tommy lift', it is available for an additional $65 to $100 fee. Please arrange and pay for this optional service at time of order. Always check the number of pieces (boxes) present against the stated waybill shipping receipt tally. As with any motor freight shipment from any distributor, be certain to carefully examine ALL of the Merchandise, not just the outside of shipping box(es), before signing and accepting delivery. It is imperative with motor freight shipments that ALL products be unboxed and fully inspected PRIOR to accepting delivery. Regardless of what the delivery driver may say, you MUST inspect fully before signing and accepting the delivery. It is the freight truck driver's job to wait while you open and inspect shipment for damages. Simply looking at the outside of the box(es) is NOT adequate. Damaged Merchandise (that particular box, not all the boxes) must be refused delivery. Once someone signs for shipment, it confirms Merchandise was received free of ANY damage and removes liability from the transportation carrier. We can only assume that damage reported later and not refused delivery, was caused by the Client, and not the freight carrier. Any subsequent attempt to file a claim for loss or damage will NOT be accepted by the transportation carrier, distributor, or Our company,

Returns and Cancellation

All returns, cancellations and/or exchanges must first be authorized in writing by at Client may not ship any Merchandise back until We supply return Merchandise authorization RMA number and address for the shipment. Orders often do not ship back to the same warehouse they shipped from originally. Contact us with invoice number and reason for return or exchange to obtain an RMA number and instructions. No returns, refunds or exchanges will be authorized more than 30 days after original purchase payment date. Design consultation services, DVDs, knit shade material, water tubes, greywater and septic system parts are not returnable for refund or exchange for any reason. Once payment has been made, custom panel orders are cut and enter the production system and cannot be cancelled after payment is made. No return on any remnants or discontinued items. Any authorized returns of Merchandise must be in the original carton, in new unused condition, and returned freight prepaid to Our designated warehouse. Merchandise originally shipped via motor freight carrier on a pallet, may not be returned via package delivery service such as UPS or Fed-Ex. Original actual shipping cost will be deducted from any refund due along with up to 15% restocking fee on the Merchandise. This restocking fee includes the 3% credit card processing on original purchase, which is not refunded by MasterCard or VISA. Please understand that items on Our website are advertised as "Free Shipping", which is to be understood as "there is no extra charge for delivery of PURCHASED Merchandise". UPS, USPS, Fed-Ex and motor freight carriers charge us a fee for delivery of Merchandise, which We must recoup on returns. Kobe, for instance, bills a flat-fee of $40 and $45 for business and residential Fed-Ex shipments and $162 and $186 for motor freight carrier drops. Sun-Mar and Servel units ship via motor freight carrier for anywhere from $120 to $300+ per unit, depending upon zip code and drop site designation. Kobe, Sun-Mar, Clivus Multrum, Quanics, Dometic and Servel returns are manufacturer-direct, drop ship items and may be subject to an additional manufacturer's restocking fee. Discontinued, clearance items are not eligible for return or exchange. If an item is returned without original packaging intact, or is damaged, found to be used, or otherwise not ready for resale, it may be refused and returned to sender at their expense, so always insure shipment.

Lost and Stolen Shipments

Tracking information is emailed following shipment on all orders so client can anticipate delivery date. Custom size shade panels are made-to-order and can take up to ten business days to produce and ship. All other 'stock items' normally ship within three business days. Should you not receive email shipping information, please send a request for tracking number in writing to: Note it can take up to 48 hours for a given tracking number to appear on transportation company website. During this time, shipment status may be listed as "order processed and ready for pickup". Traditionally, this just means the shipment has not yet reached transportation company terminal and scanned after being unloaded from truck that picked those package(s) up. Overdue shipments must be reported to merchant in writing within one week after anticipated delivery date. Cardholder hereby agrees that only two possibilities exist for a shipment that did not arrive as anticipated. Possibility #1) Transportation company shows shipment as still being in-transit. In this case, merchant will file a 'tracer' request on behalf of cardholder with transportation company and they will search for box(es) at all company freight terminals. Cardholder is required to fully cooperate by filling out any forms requested, returning any voice messages left, and replying to any email messages sent by transportation company or merchant. Your patience and consideration is required and greatly appreciated while transportation company attempts to find the shipment. Replacement or refund is authorized solely at merchant discretion. Cardholder is not permitted to cancel order. Cardholder is not permitted to dictate choice of replacement or refund. And cardholder is not permitted to dictate time frame for settlement and ultimate delivery date for merchandise. Possibility #2) Transportation company shows shipment as being delivered. In this case, merchant will file a 'lost shipment' claim on behalf of cardholder with transportation company. A lost shipment claim can take up to two weeks to resolve and unfortunately, the transportation company rarely, if ever, pays the insurance claim. Ideally, we only ship to cardholder, personally, at their residence or business 'home' credit card billing address, but regardless of designated drop site and receiving person and whether or not a signature was required at time of delivery, cardholder is solely responsible for merchandise security after drop is confirmed by transportation company. After transportation company confirms delivery to shipping address, no signature required, there will be no refund or replacement for lost or stolen merchandise for any reason. Cardholder must immediately file a theft report with their local police department for item stolen from property or designated drop site. Cardholder hereby agrees to relinquish any and all right to file a credit card chargeback sales reversal for merchandise lost in transit by transportation company or merchandise reported lost or stolen after delivery is confirmed by transportation company. Should cardholder file a chargeback in violation of this terms of service agreement, cardholder will be held responsible for reimbursement of any and all merchant services processing fees incurred as a result of the frivolous chargeback, which can be anywhere from $35 up to several hundred dollars.

Shade Panel Production

Our commercial grade knitted shadecloth carries a one year manufacturer's replacement warranty against defects in material and workmanship. You can expect at least 5 years of service when installed properly and well over ten years when used seasonally in a temperate climate. Client must inspect shade panels within one week of delivery in order to be able to report any damages. Rips, tears, and aesthetic damage you find more than one week after delivery are not reimbursed or replaced by the freight carrier or Additionally, merchandise that has been installed is not eligible for return or replacement for damage claims. Fabric is knitted polyolefin, primarily high density polyethylene HDPE, specially treated for durability and UV resistance. Wind damage from loose panel whipping, snagging, and abrading against the structure or cable framework is much more harmful in the long run than simple exposure to sunlight. Knit shade material should be installed hung underneath, not pulled across the top of cable or framework, to avoid abrasion and snagging damage. Chemical, fire, heat, abrasion, and snagging damage are not covered under manufacturer warranty. Shade panel warranty inspection returns must be authorized in advance and returned freight prepaid to designated location for visual inspection. will only pay the cost to ship warranty repaired or replaced merchandise back to client after inspection confirms damage was a material or workmanship defect. The following are trade-standard, non-valid reasons for requesting warranty inspection: First, there is no up-down, right-left, top-bottom or front-back reference point for any panel. Panel 'Width and Length' are measured from outside-edge to outside-edge of the sewn perimeter hem at the four corners only. Knit material has inherent tension and flex in the looming process that will resolve aesthetic issues when installed taut with rope lacing. Grommets on one side of panel are unlikely to line up with grommets on the opposite side or from one grommeted pinch pleat to the next. Exact one foot on-center grommet spacing, specific grommeted pinch pleat centering, and special placement on a particular side for grommets is not warranted. Any panel over 12 foot wide may have a noticeable factory knitted loom splice seam without notice in advance since the 20, 26, and 32 foot wide stock roll width fabrics are manufactured on side-by-side looms. We traditionally cover this seam with a grommeted pinch pleat, but it is possible to order plain cloth without a center GPP, per automated quoting form. Aesthetic issues are not warranted. For instance, the White 50% color knitted shade material can sometimes arrive with patches of orange discoloration and spotting as a result of the manufacturing process. This discoloration will dissipate after installation in the sunlight. Shade material may always be slightly wrinkled from rolling onto storage tube or shipping and knit appearance can vary from sample swatches presented and may also vary between various stock widths. Minor aesthetic flaws in knit appearance, stitching, and snags are not a structural panel failure problem and not warranted. Shade material is lockstitch knitted to prevent structural unraveling. Longevity is the same regardless of aesthetic appearance flaws in the fabric knit or perimeter webbing. If need be, one can use needle and thread to pull small flaws together and super-glue sealed. It is not considered a warranty-related defect unless it affects panel performance. Special fire resistant certified shade materials are not available. The finish 'Length' ordered is what we produce by cutting enough fabric to fold hem and GPP. The only time to anticipate deviation in finish dimension purchased is when 'Width' is a stock material width of 6, 8, 10, 12, 20, 26 and 32 foot. Then, finish 'Width' is likely going to be two to three inches less after folding and sewing perimeter hem and any length-wise grommeted pinch pleats. ALL other times, the size panel you request is the finish size we do our very best to produce. Knitted shade netting is inherently difficult to work with due to tension releasing when cut to custom sizes, so trade-standard warranty for free replacement is a four inch tolerance. As measured at four corners, any error of five inches, or more, is warranted for free remake, replacement, or refund at our sole discretion. This accuracy guarantee does not apply to shapes other than rectangles or any panel dimension over 32 foot. Errors of less than five inches are considered for remedy on a case-by-case basis only when the panel has not been installed and can be resold as a new-unused remnant. Special grommet placement requests are not warranted and grommet spacing at exactly one foot on center is not warranted.
