80mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2m

For new build ground floors chasing target U-values, 80mm Kingspan Thermafloor® TF70 often brings a single-layer solution within reach. A thermal resistance of 3.60 m²K/W, off a 0.022 W/mK PIR core, meets compliant floor U-values across many perimeter-to-area ratios without a second layer. The board carries composite foil on both faces and a declared 120 kPa compressive strength for floor loading. A compliance-minded thickness for new ground floor construction.

Benefits

• 3.60 m²K/W thermal resistance
• Reaches compliant U-values as a single layer on many floors
• Core rated at 0.022 W/mK
• Faced both sides with low emissivity composite foil
• New build and retrofit ready
• Handles floor loads at 120 kPa (10% compression)
• Manageable weight, simple to install
