Property across Carmarthenshire runs to rural farmhouses and market-town stock with steady conversion and extension demand — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
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.
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.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
