100mm Kingspan TF70 ThermaFloor PIR Insulation Board 2.4m x 1.2

100mm Kingspan Thermafloor® TF70 pulls double duty: a strong single layer for new build floors, and the base layer when a two-layer build-up is specified. Its 4.50 m²K/W thermal resistance, from a 0.022 W/mK PIR core, reaches low U-values on its own, and where more is needed it takes a second offset layer on top. Low emissivity foil faces both sides, and each sheet covers 2.88m². A round-number workhorse for demanding floor specifications.

Benefits

• 4.50 m²K/W thermal resistance
• Works as a single layer or the base of a two-layer build-up
• 0.022 W/mK conductivity across the range
• Low emissivity composite foil on each face
• New build and renovation applications
• 120 kPa compressive strength for floor loading
• Compatible with underfloor heating
• Quick to cut and position on site
