UV1 Protection: UV resistant on one side, effectively blocking harmful UV radiation and preventing yellowing.
Sheet(s) ends can be pre-taped with aluminium and anti-dust tape. The aluminium tape is placed at the top of the sheet and the anti-dust at the bottom of the sheet.
We will always endeavour to keep to your measurements however, there is an industry standard tolerance of +/- 5mm when cutting.
The largest sheet size we can offer in this thickness is 2.1m x 7m (WxL).
The flutes in the material run parallel to the length of the sheet.
This material is cut to your individual requirements; therefore, they are bespoke and non-returnable.
Materials may vary in brands due to supplier availability, we cannot guarantee a particular brand when your order is placed.
We recommend you don’t exceed 900mm width sheets without the correct supports.

Our 25mm multiwall polycarbonate sheets are Class 1 Fire Rating BS476/7.

Twin-wall and Multiwall polycarbonate sheets are UV-protected, but only on one side!

Look for the protective film with writing on it — this is the UV-protected side and should face the sun. The other side has no UV coating and should face away.

Pre-taping Service: Sheets come with aluminum and anti-dust tape applied to the ends of the sheet to prevent dirt and debris from entering the flutes. If you don’t want taping, please specify at purchase. During preparation, a 10mm strip of protective film is removed, leaving a visible score line; this is standard practice and does not impact quality.

The open ends of the sheets need to be sealed with sheet closures.

We cannot guarantee where the blade lands when cutting the sheets, so it is not possible to ensure hard edges on all panels.

Please store and lay this material flat in a cool, dry place prior to installation.
