Opening Rooflight Coxdome


Our Upstands are designed to provide a watertight thermal break between the Finished roof and the rooflight. They have excellent thermal insulation properties they are a more thermally efficient solution to the standard builder’s kerb and help improve the overall ‘U’ value of the unit.

Made from high impact resistant PVC-u all of our Upstands are watertight welded and we use a double wall to add strength. The inside is UV stable ensuring the brilliant white finish so there is no need for internal decoration.

All Upstands are compatible with most flat roof membrane systems including single ply, GRP, hot melt, asphalt, liquid and lead.
