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. 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. Step 3: Slide the base under the sheet and attach it to the beam. 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. Make sure that screws do not bend, tear or exert excessive pressure on the profile. Step 1: Use screws to attach the base connecting profiles to the roof beams. Installation Instructions for Roofing a Beamed Structure To anchor to non-metal structures, drill 7 mm holes 50 cm apart in the base for the beam structure or according to the position of the purlins.For curved roof buildings, cut the connecting profile cap 2 cm longer than the base. Cut the base profile and the cap to the length required.Attach the edge profile to the sheet within the short side on the top of the sheet.Drill drainage channels to allow for the flow of condensed water along the profiles used for the bottom section of the building's roof.Use a metal saw to cut the aluminum edge profiles into pieces matching the width of sheets to which they will be attached.Attach ventilating edge tape to the lower edge and sealed edge tape to the upper edge.Fold back the printed sheet protection film 10 cm.Note: We recommend only using Interstate Plastics' Aluminum Vent Tape with twinwall and multi-wall polycarbonate. UV-resistant Twinwall is twelve times lighter versus glass and the resins comprising the material are specially developed for excellent flame retardant properties. Beneficial infrared light passes through the material promoting an ideal growth environment. Twinwall's surface is protected from the degradation effects of UV radiation by a proprietary co-extrusion process. Insulation properties will increase depending on the material's thickness. Twinwall's notorious double paneled sheets serve to trap air, therefore increasing the product's insulation strength. Twinwall is attractive, durable, easy to install, and has the impact resistance and UV protection to withstand anything you can throw at it. Twinwall polycarbonate 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. No returns or refunds will be accepted once the material ships. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).Īll sales on twinwall are FINAL. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. 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. The sliding end hook is designed for two different types of measurements. Please be aware that some measuring tapes may have even smaller increments.įeatures of a Measuring Tape: Sliding End Hook For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". As the increments decrease, so does the length of the mark. Measure by counting the increments beyond the nearest inch. In between the inch markers you’ll find 16 equally spaced tick marks. As each cut is nominal, even the slightest miscalculation could be costly.Įxtend your tape measure several inches to find the 1 and 2 inch markers. Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. Please review our full return and shipping policy here. 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. If you need an over- or undersized item, note it under "Comments" during Checkout. How To Measure and Cut-To-Size Policy Īs per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. ![]()
