Acoustic triple glazing in Gwynedd
From Bangor to Porthmadog, we arrange acoustic triple glazing for homes across Gwynedd, with every quote fixed for the specification shown.
Quieter bedrooms: the glass spec that actually cuts noise. Acoustic triple glazing combines a three-pane unit with at least one laminated acoustic pane and panes of different thickness, which together reduce traffic and aircraft noise more than a standard unit.

Rules 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.
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
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
Questions
How much extra is acoustic glass?
Comparing our guide prices, acoustic glass adds about £50 to £200 a window, inc VAT, depending on size.
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 you cover all of Gwynedd?
We arrange surveys and fitting across Gwynedd.
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.
