Kooltherm K5 is a premium-performance external wall insulation board for masonry walls. With a thermal conductivity as low as 0.021 W/mK, it allows for extremely thin wall constructions. The boards are suitable for use behind traditional and lightweight polymer-modified renders and can be retrofitted externally to existing properties without disturbing the occupants as all work is done from the outside.
