Property across Cornwall runs to granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

The lantern doesn't, but the junction detail differs: EPDM wraps the kerb, GRP laminates onto it, felt is torch-dressed. We supply the right drawing for each.
Almost always the junction, not the lantern — short upstands, membrane finished under rather than over the kerb, or missing seals. Build the kerb right and dress the membrane right, and the assembly is dependable for decades.
A timber kerb at least 150mm above the finished roof surface, built to the lantern's external footprint. We issue exact dimensions at order so it's ready before the lantern arrives.
On installed projects, we coordinate it: the roofer dresses the membrane over the kerb, we bed and seal the lantern onto it. Supply-only orders include junction drawings for EPDM, GRP and felt so your roofer details it correctly.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
