Whether it's a single lantern over a Helston kitchen or a multi-roof development, our atlas roof lanterns service pairs supply-only pricing with nationwide installation — and Cornwall is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Cornwall market is defined by granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs — and our Helston installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Helston alongside Launceston, Truro and Falmouth and the rest of Cornwall — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Atlas works from a 20-degree pitch, lower than most competing systems. That keeps the lantern's overall height down, which helps with proportion on single-storey extensions and with permitted-development height limits.
Yes — slimness hasn't cost performance. The fully thermally broken profile with argon-filled solar units reaches U-values around 1.0 W/m²K, ahead of Building Regulations requirements.
Anything from roughly 750mm × 750mm up past 6 metres in length. Every lantern is fabricated to your exact external kerb dimensions rather than forced to a stock size.
Yes — supply-only Atlas orders ship UK-wide with full fitting documentation, and installed projects are handled end to end by our own teams.
Yes — installation is available across Helston and Cornwall, and if you'd rather buy supply-only, kerbside delivery to Helston is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Helston usually come back the same working day, and installed projects are priced after a free survey.
