Customer Reviews
Smooth order and delivery
I bought a few rolls of Loft Insulation Rolls for my garage conversion. The ordering process on the website was straightforward, no weird glitches or anything. It was easy to find what I needed and checkout. Delivery took about four days, which was exactly what they quoted when I placed the order. Everything arrived well-packaged and undamaged. I even had a quick question about installation and used their online chat; the person who responded was helpful and knew their stuff, which was a nice surprise. The insulation itself is decent quality, did the job for sure. Overall, a solid experience and I'd probably use them again if I have another project.
Celotex boards arrived quickly
I ordered some Celotex Boards for my attic project, and they got here pretty fast, like two days earlier than the tracking said. They were all in good shape, no dents or anything. Made the job a lot easier than I expected, glad I went with them.
Good quality Rockwool
Needed Rockwool Slabs. Ordered online. Delivery was on time. Product was as described and good quality. Happy with purchase.

Got a big order for a new build, is there any discount for buying a lot of stuff? Like multi-buy or bulk savings?
Is Insulation Superstore a reliable place to buy from? Never used them before.
Do these guys do any kind of trade discount? I'm a builder and always buying insulation.
Hey, wondering how long delivery usually takes to, say, Manchester? Need some PIR boards for a job next week.
Do they deliver to Northern Ireland? Or is it just mainland UK?
