Ballycotton House
This project used four of our advanced insulation products in its floor, wall and roof.





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.
