The best energy performance of any window type: no opening gaps. A fixed or picture window does not open; it is one large pane in a slim frame, used to frame a view or bring in light.

Winter light and glass choice in Caernarfon

On the shortest day, Caernarfon gets about 7 h 32 min of daylight and the midday sun reaches only about 13° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

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.

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

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 Caernarfon

Can a fixed window be the escape window?

No. An escape window must open. We keep or add an opening window where one is needed.

How heavy is a large triple glazed pane?

Roughly 30 kg per square metre with 4 mm glass, more with thicker or laminated panes. A 3 m by 2 m unit can weigh around 180 kg.

Do I need permission for triple glazed fixed and picture windows in Caernarfon?

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.

How long does it take to get triple glazed fixed and picture windows fitted in Caernarfon?

After the survey, typical manufacture time is 4 to 8 weeks, and most homes are fitted in 1 to 4 days.
