Triple glazed tilt and turn windows in Gwynedd
Homes across Gwynedd, including Bangor, Holyhead and Porthmadog, can have triple glazed tilt and turn windows measured, made to order and fitted.

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.

Rules in Wales
The rules for replacement windows in Wales are set by Approved Document L for Wales (2022 edition, with 2024 amendments): 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
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.
- 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
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.
Are tilt and turn windows secure?
Yes. They lock at several points around the sash, and the tilt position stays locked along the sides.
Are tilt and turn windows more expensive?
Our guide puts them about a quarter above a standard casement of the same size, in line with UK market figures.
Do you cover all of Gwynedd?
We arrange surveys and fitting across Gwynedd.
Do I need permission for triple glazed tilt and turn windows in Wales?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
