What is poly roof?
Polycarbonate roofs are strong, plastic materials stronger than PVC. The hybrid material can withstand high temperature and reflects UV rays. Most reputable contractors use them as roofs for public structures and commercial applications in the form of conservatories, patios, and decking areas.
What is polycarbonate roof panel?
Polycarbonate is a high-impact, strong material, which blocks harmful UV rays. Its lightweight properties make it easier to install. Polycarbonate roofs are often used in decks, patios, and garages to allow for transparency while maintaining durability.
What is PVC roofing?
What is PVC roofing? Made from polyvinyl chloride (or in layman’s terms, plastic), PVC is a great single-ply roofing solution. It’s made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM).
What is uPVC roofing sheet?
UPVC Multilayer Roofing Sheets is a modern rigid three layer Unplasticized poly vinyl chloride (uPVC) roofing sheets. The advanced technology of manufacturing ensures superior quality and performance of the roofing product. This uPVC is the best replacement for conventional asbestos, metal G.I.
What is FRP roofing sheet?
Fibre Reinforced Plastic ( FRP) Roofing Sheet.
Which is better polycarbonate or PVC?
Polycarbonate is even stronger than PVC (apparently it’s almost impossible to break it, but we don’t want to tempt fate…). This means, of course, that it costs more. PVC has another advantage: polycarbonate can scratch, whereas PVC rarely does.
What is TPO in roofing?
What is TPO Roofing? Thermoplastic Polyolefin is a single-ply roofing membrane that is one of the fastest-growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.
What is TPA roofing?
TPA Roof Membrane is a white thermoplastic single ply roof membrane which is comprised of an elastomeric tri-polymer alloy based on Elvaloy® and blended with CPE and PVC. TPA Roof Membrane is reinforced with a high strength, wick resistant polyester fabric.
What FRP means?
Fiberglass-reinforced polymer
Fiberglass-reinforced polymer is a strong, lightweight building material that resists corrosion. FRP is sometimes called composite because it’s made of a combination of materials that work together for even stronger performance.
How strong is polycarbonate?
Polycarbonate typically has a tensile strength of between 55–75 MPa (force per unit area). With regards to tensile strength, another plastic alternative such as acrylic is roughly 4-8x stronger than glass, whereas polycarbonate is up to 200x stronger.
What is corotherm multiwall polycarbonate?
Produced by the national plastics distribution company, Ariel Plastics, Corotherm multiwall polycarbonate sheets are a lightweight, impact-resistant glazing and roofing material. Shop our wide range of Corotherm products including glazing bar, breather tape, super fixing buttons, polycarbonate sheet and more.
How do you install flashing on a corotherm roof?
At least one vertical rib of each Corotherm sheet should engage within the glazing bar. Attach the side flashing to the side of the roof, then check the important 3mm expansion clearance at the side of the sheet and a 10mm expansion gap at the top of the slope.
What is the expansion allowance for a corotherm sheet?
Note: All Corotherm sheets must have an expansion allowance of 3mm around all fixings and 3mm/metre for both the length and the width of the sheet. Mechanical fixing at the lower end of the sheet using a centrally positioned fixing button is recommended to prevent any downslope migration of the sheet.
How do you cut corotherm sheets?
For cutting curves, use a fine toothed jigsaw. Cutting dust may be removed by vacuum. If any dust is held in the flutes by static, simply leave the sheet until the static charge dissipates, then vacuum. Fix sealing tape at the top end of each piece of Corotherm and perforated breathing tape at the bottom.
