Rules 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
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.

Questions
Does triple glazing reduce noise more than double?
A little: the third pane adds about 3 dB, sometimes less. Laminated acoustic glass makes the bigger difference, whether in a double or triple unit.
Will acoustic glazing block all traffic noise?
No glazing makes a room silent. Well-specified acoustic glazing makes a clear, noticeable reduction, especially in the low rumble of traffic.
Do trickle vents let noise in?
Standard vents can. Acoustic trickle vents are designed to keep ventilation while reducing sound.
Do you cover all of South Glamorgan?
We arrange surveys and fitting across South Glamorgan.
Do I need permission for acoustic triple glazing in Wales?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
