Triple glazed tilt and turn windows in Llantwit Major
From the first measure to the handover pack, we handle triple glazed tilt and turn windows for homes in Llantwit Major and the rest of South Glamorgan.

A strong choice for flats, upper floors and escape windows. A tilt and turn window opens inwards in two ways: tilted at the top for secure ventilation, or swung fully open like a door for cleaning and escape.
Winter light and glass choice in Llantwit Major
Winter days in Llantwit Major 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 tilt and turn windows in Wales
In Wales, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Llantwit Major
Are tilt and turn windows secure?

Are they suitable as fire escape windows?
Turned fully open, they give a large clear opening, which often meets escape requirements. We check the size on survey.
How long does it take to get triple glazed tilt and turn windows fitted in Llantwit Major?
After the survey, typical manufacture time is 4 to 7 weeks, and most homes are fitted in 1 to 4 days.
Do I need permission for triple glazed tilt and turn windows in Llantwit Major?
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.
