Review: "Made a big difference in my garage temperature" - "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."
Review: Great product - 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
