Triple glazing for new builds and self-builds in Barry
We arrange surveys and fitting of new-build triple glazing in Barry and the CF62 area, with a written, fixed quote after a free survey.
Window and door packages priced from drawings and fitted to your programme. Triple glazing is not required by Building Regulations for new homes, but it helps a new dwelling meet its overall energy target.
Winter light and glass choice in Barry
On the shortest day, Barry gets about 7 h 50 min of daylight and the midday sun reaches only about 15° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for new builds and self-builds in Wales
For a new home in Wales, windows and doors are approved through the build’s own building control application: the limiting value is 1.4 W/m²K, stricter than England. The house itself needs planning permission.
VAT: supply and fitting by a VAT-registered contractor in the construction of a new home is normally zero-rated, so new-build guide prices are shown without VAT; supply-only purchases carry 20% VAT, which self-builders can usually reclaim through HMRC’s DIY housebuilders scheme.
How it works
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
