Product Description
PIR (polyisocyanurate) insulation boards offer high thermal performance in a slim profile, but different ranges are optimised for different parts of the building envelope. Start by selecting the application (wall, roof, floor, or internal lining), then compare like-for-like products using the key characteristics below.
How do I choose a PIR board?
The guide below explains the key facets that usually matter when choosing a PIR board. Compare products at the same thickness and size first, then check performance and certification details.
1) Application (where it’s used)
Typical values: cavity wall (partial/full fill), pitched roof, flat roof, floor, internal lining.
Why it matters: determines facings, detailing, and the correct compliance evidence for the build-up.
2) Thickness & board size
Typical values: 200mm in 2400×1200mm boards.
Why it matters: thickness drives thermal resistance; board size affects handling, joints and coverage.
3) Thermal conductivity (λ)
Typical values: 0.022–0.022 W/mK.
Why it matters: lower λ means more insulation per mm, which helps you hit U-value targets.
4) Compressive stress
Typical values: 140–140 kPa.
Why it matters: key for floors and roofs where loads are transferred through the insulation.
5) R value (thermal resistance)
Typical values: 9.09–9.09 m²K/W.
Why it matters: higher R improves overall build-up performance; combine with other layers to meet U-values.
6) Certification & reaction to fire
Typical values: varies by range (DoP, BBA, EN standards, Euroclass rating).
Why it matters: supports specification, compliance, and assurance in regulated build-ups.
Choose PIR insulation by application
Selecting the application first helps you compare like-for-like boards at the same thickness and size.
