The 60mm insulation suits a broad spectrum of applications, from solid concrete ground-based floors through to beam and dense block construction, suspended timber ground floors, and timber floors laid on battens.
Throughout manufacture, Kingspan 60mm PIR receives a low emissivity composite foil facing on both surfaces. This reflective layer boosts the thermal resistance of any unventilated cavity positioned adjacent to the board.
60mm Kingspan Thermafloor TF70 utilises Nilflam® technology at its core, a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. The manufacturing process employs a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).
When assessed to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 60mm Kingspan PIR insulation typically achieves compressive strength exceeding 150 kPa at 10% compression.
Under BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties) assessment, this product typically demonstrates resistance well above 100 MNs/g.
The lifespan of 60mm TF70 Floor Insulation depends on correct installation, adequate structural support, and appropriate usage. When properly installed, it can perform reliably for many decades.
60mm Kingspan Insulation TF70 achieves an F Euroclass rating under System 4 AVCP. When deployed in pitched roof applications with suitable roof covering, it meets national standards for external fire exposure.
