Looking at new-build triple glazing for a home in Penarth? We survey, quote and fit across South Glamorgan, and the CF64 postcode district is part of that.
Triple glazing that gives your energy calculation headroom. 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 Penarth
Winter days in Penarth are short: about 7 h 50 min of daylight on 21 December, with the sun peaking near 15°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote

Questions from Penarth
Can you price from drawings?
Yes. Send your drawings or window schedule and we will price a package, then confirm sizes on site before manufacture.
Is triple glazing mandatory for new builds?
No. Neither the current rules nor the Future Homes Standard make it compulsory. Triple glazing helps meet the overall energy target.
Do I need permission for new-build triple glazing in Penarth?
In Wales, a new home needs planning permission, and its windows and doors are approved through the build’s own Building Regulations application rather than as replacements.
How long does it take to get new-build triple glazing fitted in Penarth?
After the survey, typical manufacture time is 6 to 12 weeks, and fitting is planned around your build programme.
