Kay-Metzeler 100mm EPS70 Polystyrene Floor Insulation Board

The Kay-Metzeler Kay-Cel 100mm EPS 70 Expanded Polystyrene Floor Insulation Board delivers outstanding thermal performance and durability for residential construction projects. This cost-effective solution is completely free from CFCs and HCFCs, making it an environmentally responsible choice for a wide range of building applications.

Engineered for installation beneath concrete slabs and precast concrete floors in domestic ground-floor construction, these 100mm sheets work perfectly when topped with chipboard to achieve Building Regulations U-value compliance.

The EPS 70 boards measuring 2400mm x 1200mm x 100mm provide excellent moisture resistance, rot protection, and resistance against bacteria, mould, and fungal growth. Non-toxic, non-irritant, and completely odourless, they integrate seamlessly with virtually all standard building materials.

Kay-Metzeler Kay-Cel Polystyrene comes in multiple grades ranging from EPS 70 and EPS 100 through to EPS 500, alongside the premium Kay-Cel Super-Plus variant. Both EPS 70 and EPS 100 represent top-tier 100mm expanded polystyrene options, delivering superior thermal insulation performance.

Characteristics

• Expanded polystyrene (EPS) resists moisture and works well alongside most building materials, except those containing solvents.
• 100mm EPS provides rot resistance, protection against bacteria, mould, and fungi, whilst remaining non-toxic, non-irritating, and odourless.
• 100mm EPS contains no CFCs or HCFCs; however, it is combustible under BS476: Part 4 testing and will burn when exposed to flame.
• Store the material in a covered location, shielded from direct sunlight and ground moisture exposure.

Certification

100mm EPS70 foamed polystyrene boards meet the requirements of Standard PN-EN 13163:2009.
