Insulation Supplies for Birmingham & the West Midlands
Across Birmingham, Solihull, Coventry and the Black Country, many of our orders go to one type of job: extending and converting the region's large stock of interwar and post-war semi-detached houses. Rear extensions, loft conversions and garage conversions all need the same core materials, and getting the build-up right first time saves trouble at inspection.
Rear and side extensions
A typical single-storey extension needs insulation in three places:
Check the U-values on your drawings or from building control, and we'll help you match board thicknesses to them.
Loft conversions
Converting a 1930s hipped roof means insulating the slopes, not the loft floor. Most conversions use pitched roof PIR boards between the rafters with a further layer or insulated plasterboard underneath to reduce cold bridging through the timbers. Leave a ventilation gap above the boards where the roof design calls for one.
If you're only topping up an existing loft rather than converting it, loft roll laid across the joists is the cheaper route. Our loft insulation guide covers the depths.
Garage conversions
A garage conversion usually means raising and insulating the floor, lining single-skin walls and bringing the roof up to standard. Insulated plasterboard and PIR cover most of it. Tell us the wall and floor construction and we'll suggest a build-up.
Delivery across the West Midlands
We deliver throughout Birmingham, Solihull, Coventry, Wolverhampton, Walsall and Dudley. Deliveries are kerbside with crane offload, so on a busy residential street make sure there's somewhere for the boards to land. For next-day dispatch, check stock with us before 10am; standard delivery is 2–3 working days.
Birmingham FAQs
What thickness of PIR do I need for an extension floor?
It depends on the U-value on your drawings and the board's thermal conductivity. Send us the target U-value and floor build-up and we'll recommend a thickness.
Can you supply the whole extension package?
Insulation, plasterboard, timber and fixings can go on one delivery. See our timber range and the OSB vs plywood guide for roof decks and floors.
Do you deliver further afield?
Yes. For Bristol, Bath and Gloucester see our South West page, and for the North West see Manchester.
