75mm PIR
One of the most popular PIR insulation options among builders, contractors, and architects, the 75mm PIR insulation proves to be a reliable answer to general insulation requirements. This multipurpose insulation sheet finds diverse use in many residential and commercial properties.
What is 75mm PIR insulation?
The high-efficiency 75mm PIR board is derived from the plastic compound known as polyisocyanurate. This is a type of stiff foam with a low moisture absorption rate. The foam is processed as a 75mm laminate with aluminium foil at the front and rear.
What are 75mm PIR used for?
75mm polyisocyanurate insulation is best-suited for:
- Insulation of internal and external walls. As long as there is enough space, you can apply them to any interior wall insulation project. Additional use cases are cavity and timber- and metal-framed wall insulation.
- Roof insulation. They can go above or below the rafters, depending on the kind of roof. Or you can cut and fix them between rafters.
- Floor insulation. You can use your 75mm PIR sheets to insulate different floors. Manufacturers and architects typically recommend the types of floors this board is ideal for.

FAQ
How to install 75mm PIR insulation?
Typically, installation involves cleaning the surface and, if necessary, cutting the board to ensure it fits the space. Fix the board into the space and secure it with adhesive or fixings. Seal the joints with aluminium foil and a vapour barrier to keep the insulation airtight. You may need to apply an additional vapour barrier — building regulations require this in some areas.
How to cut 75mm PIR insulation?
First, measure the board to ensure it matches the area to be insulated. Next, cut through the marked line using a saw or utility knife. A fine-toothed saw with a sharp blade ensures a clean and precise cut.
How much 75mm PIR insulation do I need?
Different sizes of 75mm PIR boards offer varying coverage. Larger boards will cover a bigger surface than smaller ones. To find out how many boards of a specific size you need, measure the work area (to be insulated), then divide this by the coverage of one PIR board.
