40mm PIR Insulation

A versatile insulation solution for diverse building applications, 40mm PIR insulation keeps your interiors warm or cool, depending on the season. This board is used for general insulation as well as room insulation.

What is 40mm PIR Insulation?

The 40mm PIR board consists of a polyisocyanurate (PIR) core flanked by aluminium foil facers on each side. PIR, a thermoset rigid foam, has excellent insulation properties and is formed by mixing polyols and isocyanates. The resulting foam is heat-treated and expanded to 40mm, then processed and shaped into rectangular boards that are fitted into diverse spaces to improve thermal insulation.

What are 40mm PIR Boards Used for?

Most contractors rely on 40mm PIR insulation sheets for wall, floor, and roof insulation in both commercial and residential settings. These sheets are ideal for internal and cavity walls since they can fit into small spaces. You can install them in floors with underfloor heating and use them to insulate timber, concrete, and suspended floors, among other types of floors. Fix 40mm PIR insulation on your ceiling or roof to meet your roof insulation needs.

Benefits of 40mm PIR insulation boards

• Lightweight — The PIR insulation 40mm board is thin and light, making it easy to carry and use.
• Easy installation — Installing the 40mm is easy work, and not just because of its lightweight design. Its entire design ensures user-friendliness, from the even, rectangular shape to the sharp, straight, square edges that make installation pain-free.

FAQ

How to install 40mm PIR insulation?

Each PIR 40mm board comes with installation instructions from the manufacturer. Follow the recommended steps for a flawless process. Remember that incorrect installation can lead to poor heat retention.

How to cut PIR insulation 40mm?

Measure the part you want to cut and mark it. It’s best to use several markings across the length or width of the board, as this will help keep your cut straight. Cut along the markings using a hand saw or utility knife. You can use any other type of fine-toothed saw with a sharp blade.

How much 40mm PIR insulation do I need?

The number of boards you buy depends on the size of the area you plan to insulate. To find out how many PIR 40mm polyisocyanurate insulation boards you need, measure the area that needs insulation in square metres and divide this by the coverage each board offers (determined by the board size).
