Available from Kingspan Insulation , these wall boards are made from fibre-free thermoset material rather than thermo plastics, and they have a Group 1 BCA fire classification.

MasterWall’s Innovative Exterior Insulation and Finishing System (EIFS) K-Series is powered by Kooltherm® K5, and it delivers the highest performance available in external rendered insulation systems.

Said to deliver almost double the thermal performance of conventional polystyrene of the same thickness, the wall boards can achieve R4.0 in 80 mm.

They have a closed cell structure which makes them resistant to the passage of water vapour, and are suitable for installation in domestic and commercial buildings.
