With a low thermal conductivity of 0.021 W/mK, Kingspan Kooltherm K5 offers premium performance external insulation for masonry walls.

Kooltherm K5 is made with a fibre-free rigid thermoset phenolic core that is faced on both sides with a glass tissue based facing bonded to the insulation core. It is also highly resistant to water vapour and has a thin design for optimal use in applications where space is limited.

These easy-to-install boards are ideal for upgrading existing properties and work perfectly behind both traditional and lightweight polymer-modified renders and dry cladding systems.

Kingspan Kooltherm K5 external wall boards can be applied from the outside, reducing disruption to those inside the building. It also offers low environmental impact, as it is CFC and HCFC free with an ODP (ozone depletion potential) of zero and low GWP (global warming potential).
