Kay-Metzeler EPS70 30mm Polystyrene Floor Insulation Board

The Kay-Metzeler Kay-Cel 30mm EPS 70 Expanded Polystyrene Floor Insulation Board delivers outstanding thermal performance and durability for residential flooring applications. This cost-effective solution is completely free from CFCs and HCFCs, making it an environmentally responsible choice for ground-floor construction projects.

Engineered for installation beneath concrete slabs and precast concrete floors, this 30mm EPS 70 board (2400mm x 1200mm x 30mm) pairs perfectly with chipboard to achieve Building Regulations U-value compliance. The material resists moisture, rot, bacteria, mould, and fungal growth whilst remaining non-toxic, odourless, and compatible with most standard building materials.

Kay-Metzeler Kay-Cel Polystyrene comes in multiple grades—EPS 70, EPS 100, through to EPS 500—with both EPS 70 and EPS 100 delivering premium thermal insulation performance.
