Customer Reviews
Consistently reliable for boards
This was my third order for phenolic foam insulation boards. Each time, the process has been smooth. The prices remain competitive, and I appreciate the consistent delivery times. My previous orders for cavity wall insulation and then underfloor heating insulation were just as good. It's why I keep coming back; I know what to expect and they always deliver on it.
Decent service, minor hiccup
I ordered some PIR insulation boards for a small extension project. The prices were competitive, especially with the multi-buy discount. Delivery was within the stated timeframe, arriving on day five. One board had a slightly damaged corner, but it was still usable for cutting. Customer service was quick to respond when I inquired about a different product's technical specs before ordering, which was helpful. Overall, a good experience, but they could improve on packaging to prevent small damages.
Fantastic insulation for the garage!
I bought garage door insulation from here and it's brilliant! My garage is so much warmer now. The website was easy to navigate, and the product descriptions were clear. It arrived quickly too, in just 3 days. I'm really happy with this purchase and will definitely be back when I need to do the shed. Highly recommend them!
Good value on loft rolls
I was looking to insulate my loft myself and found Insulation Superstore had the best price on glass mineral wool loft rolls. I signed up for the newsletter and got a small offer, which helped. The delivery took about 4 days, but it was worth the savings. Felt like a good deal overall.

Anyone used their price match thing? Found some Rockwool cheaper at Wickes, wonder if it's worth trying.
I'm a new customer, is there a discount for first-time buyers or anything? Planning a big order.
Thinking of getting some multifoil insulation but heard it's a pain to install. How does it compare to rigid boards like Celotex?
What's the typical delivery time for like a pallet of insulation? Need it by next week latest for a job in Manchester.
Can you return insulation if you order too much? Like, if I have a few leftover boards?
