Triple glazed bifold doors in County Tyrone
Homes across County Tyrone, including Omagh, Strabane and Cookstown, can have triple glazed bifold doors measured, made to order and fitted.

Open the wall in summer, keep the warmth in winter. Bifold doors are made of several panels hinged together that fold and slide to one or both sides, opening almost the full width of the opening.

Rules in Northern Ireland
Northern Ireland sets replacement door limits through Technical Booklet F1 (2022): 1.8 W/m²K. Replacing 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 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.
- 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 are triple glazed bifold doors?
Our guide starts at £4,295 fitted for a 3-panel aluminium bifold about 2.4 m wide and £6,295 for 5 panels, inc VAT.
Do I need building regulations for new bifolds?
Replacing an existing door is covered by the replacement rules. A new or widened opening is structural work that needs building control approval.
Are bifolds warmer with triple glazing?
Yes. The glass is most of the door area, so triple units cut heat loss and keep the inner surface warmer.
Do you cover all of County Tyrone?
We arrange surveys and fitting across County Tyrone.
Do I need permission for triple glazed bifold doors in Northern Ireland?
In Northern Ireland, check with your council planning office before changing the style, material or size of a door, and always for listed buildings and flats.
