Corrapol Stormproof Clear Corrugated Roofing Sheet

(Choice of length available)

Strongest and clearest corrugated roofing!

Excellent clarity and superior strength clear corrugated roof sheet that is 200 times stronger than glass of same thickness. Incorporates a UV protection layer, so won’t yellow or become brittle over time.

There are four lengths available of Corrapol Stormproof sheets, all of which provide exceptional clarity, and their superior strength means they are not likely to break during installation, like some cheaper sheets.

These sheets are perfect for providing strength and clarity to new and replacement roofs, but can also be used with an opaque corrugated roof, like Corrapol-BT. The profile of both sheet types match, meaning that Stormproof sheets can be positioned amongst the corrugated bitumen sheets to add light into the space beneath.

Features & Benefits

  • High impact strength - extruded from virtually unbreakable resin
  • Excellent clarity - clearer view and allows more light through
  • Quick and easy to fit - simply overlap sheets to cover roof
  • Easy to handle - lightweight, easy to cut and crack resistant
  • UV protected - won’t yellow or become brittle like cheaper sheets
  • Longer lasting product - increased 25 year estimated life span
  • Part of complete system - variety trims and fixings available
