Thermo-teK GB 020-060 ALU is a Glass Mineral Wool insulation board with excellent thermal resistance, bonded on one side to a tear-resistant, glass mesh reinforced aluminium foil that acts as a water vapour barrier and ensures a closed-fibre environment (improved dust protection in the room and during installation).

It received the „Eurofins Indoor Air Comfort Gold“ award therefore its use ensures a better room atmosphere while also making handling considerably more comfortable.

Thermo-teK GB 020-060 boards are available in densities : 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60 kg/m3
