The Denbighshire market is defined by market-town terraces and vale farmhouses with heritage-sensitive installs — and our St Asaph installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover St Asaph alongside Prestatyn, Rhyl and Denbigh and the rest of Denbighshire — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

On current systems, around 40mm at the ridge externally. Claims much below that usually measure a different part of the frame — we'll always quote like-for-like ridge and hip dimensions so you can compare honestly.
No — the slimness comes from structural bonding and better alloys, not thinner-for-the-sake-of-it metal. Each lantern is engineered for its span and site wind loading.
Tighter tolerances, structural glazing and higher-spec profiles all add manufacturing cost, and installation needs more care. It's the premium tier of the lantern market and priced accordingly.
Yes — St Asaph is inside our standard Denbighshire coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to St Asaph on dedicated glass transport.
