Acoustic triple glazing · Northern Ireland
Acoustic triple glazing in County Londonderry
Homes across County Londonderry, including Derry, Coleraine and Magherafelt, can have acoustic triple glazing measured, made to order and fitted.
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 Northern Ireland
The rules for replacement windows in Northern Ireland are set by Technical Booklet F1 (2022): 1.6 W/m²K, or a Window Energy Rating of band C or better. Replacing windows or external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Planning: Check with your council planning office before changing the style, material or size of windows or doors, and always for listed buildings, conservation areas and flats.

Questions
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.
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.
How much extra is acoustic glass?
Comparing our guide prices, acoustic glass adds about £50 to £200 a window, inc VAT, depending on size.
