Kooltherm K5 60mm (8 Boards Per Pack)

Kooltherm K5 is an advanced external wall insulation board for masonry walls. A thermal conductivity of as low as 0.021 W/mK provides unrivalled thermal performance and 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.
