As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under \"Comments\" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.
Measure Twice, Cut OnceSince custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring TapeExtend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2\" has a bigger mark than 1/4\" which has a bigger mark than 1/8\". The smallest mark follows at 1/16\". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End HookThe sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

All sales on twinwall are FINAL. No returns or refunds will be accepted once the material ships. Blue polycarbonate twinwall sheet from Interstate Plastics provides an endless range of glazing and roofing applications, for extreme weather conditions, and is known for its light-transmitting and reflective qualities. Twinwall is attractive, durable, easy to install, and has the impact resistance and UV protection to withstand anything you can throw at it. Twinwall's notorious double paneled sheets serve to trap air, therefore increasing the product's insulation strength. Insulation properties will increase depending on the material's thickness. Twinwall's surface is protected from the degradation effects of UV radiation by a proprietary co-extrusion process. Beneficial infrared light passes through the material promoting an ideal growth environment. UV-resistant Twinwall is twelve times lighter versus glass and the resins comprising the material are specially developed for excellent flame retardant properties. Note: We recommend only using Interstate Plastics' Aluminum Vent Tape with twinwall and multi-wall polycarbonate. 6mm (.236") and 8mm (.315") wall should be used with 1"x108' tape. 10mm (.394") and 16mm (.630) wall should be used with 1.5"x108' tape. U Profile #212 U Profile #213 U Profile #214 U Profile #215 Preparing the Sheets Preparing the End Profiles Preparing the HPC Connecting Profiles Installation Instructions for Roofing a Beamed Structure Step 1: Use screws to attach the base connecting profiles to the roof beams. Make sure that screws do not bend, tear or exert excessive pressure on the profile. Step 2: Place the sheet on the top of the base profile support edges, with the side covered by the printed protective film facing upwards. Step 3: Slide the base under the sheet and attach it to the beam. Step 4: Place the side spacer profile onto the roof beam and attach the cap to the base by hammering into place with a rubber mallet. Steps 5 to 7: Continue adding sequentially, a sheet (step 5), a base connecting profile (step 6) and a cap (step 7) until reaching the end of the building. After completing installation, remove all the printed protective film from the sheets. General Cleaning Removing Oil and Tar Removing Heavy Markings (e.g. graffiti, paint, marker, inks, glazing components) Removing Adhesive-Backed Labels Removing Scratches Special Note: Always rinse edges of polycarbonate with generous amounts of warm water, as the edges of polycarbonate sheet are not protected with an abrasion and chemical resistance hard coating. Planning Creativity The right-hand area, where the curves become more horizontal, measures specifically and only sheets clamped at 2 sides. The left-hand area measures specifically sheets glazed in frames with supports perpendicular to the sheet ribs. For structures built in areas with variance in meteorological conditions, the use of adequate safety factors is recommended in order to reduce risks. The data and information in this section is given in good faith but only as basic technical support for engineers of various structures. In no way can this information be substituted for the responsibility and liability of the designing engineer of a structure as determined by law. The information pertains to the roofing material only and does not in any way determine the strengths required in a supporting structure or in various glazing systems.Twinwall Accompanying Parts Guide: .236" (6mm) Twinwall Parts

Mega-Lock Aluminum Glazing System Working with Polycarbonate Twinwall How to Clean Polycarbonate Sheet
1. Rinse surface with warm water to loosen preexisting dust, dirt and grime.
2. Gently wash surface with a mild soap and a soft microfiber cloth or sponge.
3. Rinse thoroughly with lukewarm water. Dry completely with a soft, dry cloth.
1. Rinse with warm water to loosen preexisting dust, dirt and grime.
2. Gently rub the surface with a 50/50 isopropyl alcohol and water mixture using a soft, non-abrasive cloth.
3. Immediately rinse material with water and dry using a soft, dry cloth.
1. Rinse with warm water to loosen preexisting dust, dirt and grime.
2. Gently rub the surface with Naphtha VM&P grade, isopropyl Alcohol, or butyl cellosolve, using a soft, non-abrasive cloth.
1. Stubborn adhesives can be removed using isopropyl alcohol, Naphtha VM&P grade or kerosene.
1. Deep scratches and gouges made by sharp objects such as keys, screwdrivers and knives cannot be repaired.
2. Fine scratches can be cosmetically hidden by using our Novus 2, followed by a polishing agent such as Novus 1.Planning and Creativity
In good architectural planning elements of the environment in which the structure will be placed must be taken into account. In outstanding architectural planning, the environment becomes an integral part of the structure.
Twinwall Polycarbonate sheeting harnesses nature to create the interior atmosphere by enlisting nature's qualities for the creative process. Realizing that the creative process in building depends on the ability to adapt the materials for the design concept, Polycarbonate Twinwall offers architects a raw material that can bring many architectural and design projects to fruition.Polycarbonate Wind Load Charts These charts show wind loads and sheet deflection that should be taken into account when designing a covering. Use of the graph indicators is quick and easy, and is intended to provide information of a type generally acceptable in civil engineering. Each chart provides data for 3 different sheet widths with the maximum proportional deflection being 1:20 or 5% of the specific width.
