The Isotex HDIII 38/17 formwork block is used to create infill walls. Inside the formwork, there is an insulating insert in eco-sustainable EPS, made of Neopor® BMBcert by BASF up to 100% recycled (Biomass).
It has a thickness of 38 cm and a continuous insulating insert of 17 cm, with a concrete cast thickness of 12 cm. Thermal transmittance U=0.15 W/m²K. The wood is mineralised with a natural mineral that makes it inert, therefore resistant to fire (REI120), parasites and atmospheric agents. Reaction to fire B,s1-d0. Excellent facade fire behaviour (Lepir2 Test).
