PIR Insulation Board 25mm - 400mm x 1200mm for use in Roofs, Walls and Floors (18)

"I bought a 6-pack of these 25mm PIR boards to insulate the walls of my garden office. The 400mm width was perfect for my stud work, requiring minimal cutting. They are incredibly lightweight and easy to cut cleanly with a sharp knife, much easier than dealing with mineral wool. I sealed the joints with foil tape, and the difference in heat retention is already noticeable. They offer excellent thermal performance for such a thin board. Highly recommended for any small or specific insulation projects."

Great product using it for van to camper conversion it’s perfect for what I need it for. Just ordered a 2nd load will probably need at least 3 more after this thank you

Very light to handle. Easy to install even for single female. You can secure to rafters just with some pressure and cutting just right. Will make some difference in my attic rafters in both summer and winter ❄️🌞

Easy to cut with sharp knife.

Used to insulte the viv for my tortoise. Keeping her warmer for longer and cheaper 👌

Good boards, already cut to required size
