The 30mm insulation has a diverse range of applications, including use in solid concrete ground-based floors, beam and dense block floors, suspended timber ground floors, and timber floors on battens.
During the manufacturing process, Kingspan 30mm PIR is bonded with a low emissivity composite foil on both sides, which serves as a reflective surface to enhance the thermal resistance of any unventilated cavity next to the board.
30mm Kingspan Thermafloor TF70 core is made using Nilflam® technology, which is a top-quality fiber-free rigid thermoset polyisocyanurate (PIR) insulant. The manufacturing process uses a blowing agent with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
When tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 30mm Kingspan PIR insulation usually surpasses a compressive strength of 150 kPa at 10% compression.
Under BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties) testing, this product typically achieves a resistance significantly exceeding 100 MNs/g.
The durability of 30mm TF70 Floor Insulation depends on appropriate installation, supportive structure, and usage circumstances. If installed correctly, it has the potential to last indefinitely.
30mm Kingspan Insulation TF70 has an F Euroclass rating under System 4 AVCP. When utilized in pitched roof constructions and placed under a suitable roof covering, it can fulfill national criteria for external fire exposure.
