Triple glazed flush casement windows in Pwllheli
Triple glazed flush casement windows for homes in Pwllheli: measured on a free survey, made to order and fitted by installation teams working for us across Gwynedd.
Traditional flush sashes, a three-pane unit and heritage colours. A flush casement window has sashes that close flush with the outer frame instead of overlapping it, copying the look of traditional timber windows.
Winter light and glass choice in Pwllheli
By midsummer Pwllheli has about 16 h 55 min of daylight, but in December only around 7 h 35 min, with the noon sun at about 14°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for flush casement 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.
Before ordering: 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
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.
- 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
