PIR (polyisocyanurate) insulation boards are rigid, high-performance boards used to improve thermal efficiency in roofs, floors and walls. They offer a better U-value than many alternatives in a slim build-up and are often foil-faced to act as a vapour control layer.
PIR boards are commonly used in pitched roofs, flat roofs, floors, walls and loft conversions where space is limited and a high thermal performance is needed.
PIR boards are stocked in a range of thicknesses, typically from 25 mm up to 150 mm, so you can meet building regulation U-values without excessive build-up.
No. PIR is a different chemistry from expanded polystyrene (EPS) and generally gives a better U-value for the same thickness. EPS is often used where cost is the priority and space is less constrained.
