Triple glazing for period homes and conservation areas in Irvinestown
If you live in Irvinestown (BT94) and want period-style triple glazing, start with a free survey: every opening measured, then a written quote that fixes the price.

Flush casements and sashes that councils tend to accept. In a conservation area, replacing windows on a house is often permitted development if the new windows look similar to the old ones, but councils can remove those rights with an Article 4 direction.
Winter light and glass choice in Irvinestown
On the shortest day, Irvinestown gets about 7 h 16 min of daylight and the midday sun reaches only about 12° 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 period homes and conservation areas 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.
Before ordering: 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.
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.
- 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 Irvinestown
Will heritage-style frames look chunky with triple glass?
They can if the sections are too slim for a full triple unit. We will show you the frame sizes and, if needed, offer a slim high-performance unit instead.
Can I put triple glazing in a listed building?
Usually not as a replacement. Listed building consent is needed and is often refused for original windows. Secondary glazing is the common alternative.
