Where: l is the thickness of the material in metres and. λ is the thermal conductivity in W/mK. The R-value is measured in metres squared Kelvin per Watt (m 2 K/W) For example the thermal resistance of 220mm of solid brick wall (with thermal conductivity λ=1.2W/mK) is 0.18 m 2 K/W.

Polyisocyanurate - Wikipedia Polyisocyanurate, also referred to as PIR, polyiso, or ISO, is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. The starting materials are similar to those used in polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol.
Kingspan Kooltherm K108 Cavity Board is a premium performance insulation with a fibre-free rigid thermoset phenolic core. As part of our Kooltherm K100 range, it provides a level of performance that is unrivalled in the world of rigid thermoset insulation materials with a thermal conductivity of just 0.018 W/m·K across all thicknesses.
