Applications

This 80mm insulation product performs well across numerous floor types, including concrete slab foundations, beam and block constructions, suspended timber ground floors, and battened timber systems.

Foil Facing Details

The manufacturing process applies a low emissivity composite foil facing to both sides of Kingspan 80mm PIR boards. This reflective layer boosts thermal performance by enhancing resistance within unventilated cavities adjacent to the board surface.

Core Material

The 80mm Kingspan Thermafloor TF70 core utilises Nilflam® technology, delivering a premium fibre-free rigid thermoset polyisocyanurate (PIR) insulation product. Manufacturing employs a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP) impact.

Compression Performance

Testing to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior) demonstrates that 80mm Kingspan PIR insulation typically achieves compressive strength exceeding 150 kPa at 10% compression.

Moisture Resistance

Under BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties) testing protocols, this product consistently delivers water vapour resistance well above 100 MNs/g.

Long-Term Performance

The lifespan of 80mm TF70 Floor Insulation depends on correct installation, adequate structural support, and appropriate usage conditions. When properly fitted, the material can maintain performance indefinitely.

Fire Safety

80mm Kingspan Insulation* TF70 achieves an F Euroclass rating under System 4 AVCP. When installed in pitched roof applications beneath suitable roof coverings, it satisfies national external fire exposure requirements.
