Kooltherm K10 phenolic core insulation sheet have the lowest thermal transmittance of any commercially available insulant; twice the R value for thickness of glass wool and expanded polystyrene, and 50% higher than extruded polystyrene.
Kooltherm is highly resistant to water vapour (with over 96% closed cells) and moisture absorption of less than 2% so can be installed in almost any weather. Further, with a surface compressive strength of 175kPa, it is highly resistant to impact damage during installation and also in use.
Kingspan Kooltherm is the best choice for any Greenstar rated building; it is BRE certified in the UK and Europe as well as being EnviroSpec certified here in New Zealand. Kooltherm K10 contains no CFC’s, HCFC’s or ozone depleting chemicals, and provides higher R values than any other commercially available material of the same thickness, reducing the on-going energy/running costs of the building.
