Opening & Vented Roof Lanterns in Hitchin

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.

We do. Hitchin and the surrounding Hertfordshire towns are core territory for both our installation teams and our supply-only delivery routes.

For Hitchin: same-day made-to-measure quotes, standard sizes delivering in around 7–10 working days, and installation slots booked to suit once the survey's done.
