Whether it's a single lantern over a St Ives kitchen or a multi-roof development, our opening & vented 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 St Ives 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 St Ives alongside Camborne, Bodmin and Wadebridge and the rest of Cornwall — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Only on certain systems — vents are normally factory-built into the roof slope. Send photos of your lantern and we'll confirm whether a retrofit sash exists for it or whether replacement is the honest answer.
Your choice: a simple wall switch, a remote, app control, or full automation that opens on temperature and closes on rain. Most kitchens land on switch-plus-rain-sensor.
Not in a quality system — the sash closes onto continuous gaskets and locks down tight. The vent panes carry the same glazing spec and guarantee as the fixed glass around them.
Over kitchens and in south-facing rooms, emphatically yes — venting at the highest point purges heat and steam faster than any window can. In cooler, well-ventilated rooms a fixed lantern plus good doors often suffices.
Yes — installation is available across St Ives and Cornwall, and if you'd rather buy supply-only, kerbside delivery to St Ives is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for St Ives usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
