Winter light and glass choice in Porthmadog

Rules for fixed and picture 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
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 Porthmadog
Do fixed windows need trickle vents?
The room still needs ventilation. If the fixed window replaces one with vents, ventilation must be provided another way, for example a vented frame or an adjacent opener.
Is a picture window worth triple glazing?
Big panes lose a lot of heat and can feel cold to sit near. Triple glazing keeps the inner pane warmer, which makes the space by the window more comfortable.
Do I need permission for triple glazed fixed and picture windows in Porthmadog?
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.
