For stratus roof lanterns in Cornwall, we offer both routes: supply-only with delivery for builders and DIYers, and full installation by our own teams in Truro, Falmouth, St Austell and county-wide.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The county's housing stock — granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — shapes our recommendations here more than any brochure could.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Two-pane lanterns for compact roofs, three-pane and contemporary hip designs for mid sizes, and multi-bar roofs for large extensions — each fabricated to your kerb dimensions.
Yes — we dispatch Stratus lanterns UK-wide for builder installation, or fit them ourselves through our nationwide teams.
Stratus is Synseal's contemporary aluminium lantern system, designed with thermal efficiency as the headline feature — chambered thermally broken profiles, warm-edge glazing and independent TUV certification of its U-values.
With the upgraded glazing package it achieves U-values around 1.0 W/m²K — comfortably beyond what Building Regulations require for replacement rooflights or extensions, and certified rather than just claimed.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
