Triple glazing for period homes and conservation areas in County Fermanagh
From Enniskillen to Irvinestown, we arrange period-style triple glazing for homes across County Fermanagh, with every quote fixed for the specification shown.

Warmth for period homes without losing their character. 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.

Rules in Northern Ireland
Northern Ireland requires replacement windows to achieve 1.6 W/m²K, or a Window Energy Rating of band C or better, which good triple glazing passes comfortably. 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.
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.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions
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 have triple glazing in a conservation area?
Often yes, if the new windows match the look of the old ones and there is no Article 4 direction. Check with your council first.
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.
Do you cover all of County Fermanagh?
We arrange surveys and fitting across County Fermanagh.
Do I need permission for period-style triple glazing in Northern Ireland?
In Northern Ireland, check with your council planning office before changing the style, material or size of windows, and always for listed buildings and flats.
