Whether it's a single lantern over a Letchworth kitchen or a multi-roof development, our korniche roof lanterns service pairs supply-only pricing with nationwide installation — and Hertfordshire is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
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 Letchworth — 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 Letchworth we also serve Bishop's Stortford, Cheshunt and Borehamwood and the wider county — so if you're comparing quotes anywhere in Hertfordshire, ours is free, fast and without obligation.
The joint engineering. Korniche components machine together so precisely that the lantern assembles without silicone, external clips or cover caps — which is why installers love it and why the finished lines look so clean.
The frame itself can be assembled on the kerb in under 30 minutes by a competent installer; a full fit including glazing and flashing is comfortably a one-day job. Manufacture lead time is typically one to two weeks.
Yes — the system is fully thermally broken with no metal-to-metal path from outside to inside, and paired with argon-filled units it achieves U-values that comfortably satisfy Building Regulations for extensions.
Every Korniche is made to order, so 'custom' is the standard. You give us the external kerb size and the lantern arrives fabricated to those exact dimensions.
Yes — installation is available across Letchworth and Hertfordshire, and if you'd rather buy supply-only, kerbside delivery to Letchworth is included in our standard service.
