Polycarbonate Domes & Pyramids - Kerb & Upstand Options

Kerbs or Upstands elevate the glazed section of the skylight off of the roof’s surface.

Usually, kerbs are manufactured in PVC although builders do construct kerbs from timber, fixing a polycarbonate dome to the top of it. ALL kerbs must project at least 150mm above the finished roof surface, this is according to current building regulations.

Builder's Kerbs

We are able to provide a polycarbonate dome from our Stardome or Thermadome collections for builders wishing to assemble a kerb from timber and secure a dome or skylight on top. We need the overall kerb size, including the fitted weathering membrane and we would then recommend a suitable polycarbonate dome.
