Hertfordshire property here means garden-city housing, 1930s semis and a fast-moving extension market across the commuter towns. That local context shapes what we recommend in Welwyn Garden City — from glass specification to frame colour — before a single quote is written.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
From Welwyn Garden City we also serve Hertford, Bishop's Stortford and Cheshunt and the wider county — so if you're comparing quotes anywhere in Hertfordshire, ours is free, fast and without obligation.
Yes — we dispatch Stratus lanterns UK-wide for builder installation, or fit them ourselves through our nationwide teams.
Stratus is Synseal's contemporary aluminium lantern system, designed with thermal efficiency as the headline feature — chambered thermally broken profiles, warm-edge glazing and independent TUV certification of its U-values.
With the upgraded glazing package it achieves U-values around 1.0 W/m²K — comfortably beyond what Building Regulations require for replacement rooflights or extensions, and certified rather than just claimed.
Yes — the square-cut internal lines and the white or heritage colour options sit comfortably in period rooms, while the same frame in anthracite reads as fully contemporary.
We do. Welwyn Garden City and the surrounding Hertfordshire towns are core territory for both our installation teams and our supply-only delivery routes.
