Opening & Vented Roof Lanterns in Alton — common questions

Does an opening pane compromise the lantern's weather seal?

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.

Are opening roof lanterns worth it?

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.

What happens if it rains while the vent is open?

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.

Can opening vents be added to my existing lantern?

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.

Do you cover Alton for installation?

Yes — Alton is inside our standard Hampshire coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Alton on dedicated glass transport.

What's the lead time for Alton?

Stocked standard sizes typically deliver to Alton within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
