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 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.
- One of the thinnest commonly used insulants for external walls – reach the required U-value with minimal thicknesses
- Ideal for buildings that can’t be insulated on the inside
- Perfect for retrofit projects with an installation process that has little to no impact on occupants
- Ideal for refurbishment projects to improve BER or meet stringent retrofit standards
- Doesn’t reduce living space, compared to insulated plasterboard
