 Trustindex verifies that the original source of the review is Google. I ordered 18 of the 40mm Soprema  PIR Insulation Boards (1200 x 2400mm), and I couldn’t be happier with the service.

Delivery was super fast, and everything was delivered with great care. The online ordering process was easy and straightforward, and the communication afterwards was absolutely fantastic.

I honestly cannot fault anything. Excellent service, great communication and a smooth, hassle-free experience from beginning to end.

Highly recommended! I would definitely order from them again.

 Trustindex verifies that the original source of the review is Google. Outstanding service from Trade Insulations. Ordered Rockwool slabs for a floor/ceiling project, and the delivery was bang on schedule.
The insulation density is so impressive I’m tempted to line my entire life with it. James messaged to check in on the delivery, proving they care as much about customer satisfaction as they do about acoustic decibel reduction. Absolute legends. Don't bother looking anywhere else
