How to cut 25mm PIR insulation?
You’ll need a saw or knife to cut a 25mm PIR insulation board. Experts at insulationwholesale.co.uk recommend using a sharp cutting tool to achieve a clean cut. Before cutting the board, measure the space where you will install it. Next, measure and mark the board to ensure you get a tight fit. Then go ahead and cut along the markings to get even results. Make sure to wear gloves, a mask, and goggles to protect yourself from the resulting debris, which can irritate the skin or affect the respiratory system when inhaled.
How much 25mm PIR insulation do I need?
This depends on the size of the space to be insulated. To determine how many 25mm PIR boards you’ll need, measure the space you plan to insulate. Add 10-15% for cuts and the bits you’ll fit around obstacles. Divide this by the PIR board coverage, which is determined by the size of the board. Many of the 25mm PIR insulation sheets on our website are 2400mm (L) by 1200mm (W).
