TwinWall Polycarbonate sheets offer many advantages over the more traditional polycarbonate profile sheets. They will provide a modern, flat look to your roof that is easy to cut and available in several colours and differing levels of thickness. Twinwall is designed to meet all of your project requirements in glazing, it is lighter and many times stronger than glass.

This high quality polycarbonate glazing sheet has a thin wall tunnel and rectangular structure which lends itself well to vertical and curved structures. It offers high impact strength, excellent light transmission, light weight, easy installation, long term weather resistance and outstanding insulation properties.


Lexan Thermoclear Twinwall polycarbonate sheeting is available in a range of colours and gauges for use in a wide range of commercial, industrial and domestic applications. Light weight, easy installation, excellent thermal insulation and solar properties. Attractive and very cost effective alternative to glass. Manufactured by Ampelite.

Both sides of the sheet have co-extruded UV protection to provide high resistance to yellowing and the damaging effects of UV radiation. This feature eliminates the problem of sheets being installed with an unprotected surface exposed to the weather with resultant UV damage. Angle cuts can be reversed, so there is also an economic gain when cutting requirements are high.

We are also able to supply other brands of twinwall for the more budget conscious buyer, however these sheets only have UV protection on one side. It is important to take note of the warning on these sheets which side must face the sun. Failing to do this may result in early yellowing of the product. The protective labels should only be removed after installation.
