Triple glazed casement windows in Aberdare
If you live in Aberdare (CF44) and want triple glazed casement windows, start with a free survey: every opening measured, then a written quote that fixes the price.

Like-for-like replacement for most post-war homes. A casement window has sashes hinged at the side or top that open outwards, the most common window style in UK homes.
Winter light and glass choice in Aberdare
Winter days in Aberdare are short: about 7 h 47 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 casement windows in Wales
Wales requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.
Planning: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.
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.

Questions from Aberdare
Can my existing casement layout stay the same?
Yes. We match the existing layout unless you ask for a change, which can matter for planning in conservation areas.
What is an egress hinge?
A hinge that lets the sash open wide enough to climb out in a fire. It is used where a bedroom window is also the escape route.
Do I need permission for triple glazed casement windows in Aberdare?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
