Swansea homeowners and trades use us for opening & vented roof lanterns because the offer is simple — honest online prices on standard sizes, same-day made-to-measure quotes, and installation available everywhere in the county.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Property across Swansea runs to terraced streets and Gower coastal homes — marine-grade frames and solar-control glass are common specs — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
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.
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.
The rain sensor closes it automatically — it's a standard part of the package, not an optional extra, so an open vent and a surprise shower never meet.
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.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
