20mm PIR

20mm PIR insulation is a versatile material widely used in construction projects. These insulation boards are made using polyisocyanurate (PIR), with each board measuring 20mm in thickness.

What is 20mm PIR insulation?

PIR insulation 20mm is made from polyisocyanurate foam, a type of plastic. The chemical processes that occur during manufacture create a sturdy foam characterised by closed cells. This structure ensures excellent heat and moisture resistance. This foam is then spread between a pair of foil facings, where it’s allowed to expand up to 20mm, before being further processed and sized into the various boards you see on our website.

What are 20mm PIR used for?

20mm PIR boards are used to insulate roofs, floors, and walls in residential and commercial construction projects. You can use them in internal walls, different types of floors, and roofs, including pitched and flat roofs.

Types of 20mm PIR

Most 20mm PIR insulation sheets have a foil-facing on each side, with manufacturers designing specialised facings for each category of 20mm PIR board. These facings have low emissivity, meaning they reflect heat generated in a room back into the room, minimising heat loss.

Benefits of 20mm PIR insulation

• They have high thermal resistance — At 0.022 W/mK, 20mm PIR boards have low thermal conductivity, which means they resist heat very well.
• They are light — Two factors make 20mm PIR sheets light in weight:
• They are made using polyisocyanurate foam, which is lighter than comparable insulation materials.
• They have a slim design and are therefore not bulky. This makes the boards easy to move around and work with.
• They are ideal for small spaces — Because they have a thin profile, 20mm PIR boards are perfect for use in areas with limited space.
• They are easy to install — Being so slim, 20mm PIR insulation is easy to cut, resize, and install.
