The Isotex wood cement formwork blocks are insulated with Neopor® BMBcert insulating insert from BASF (15% recycled or 100% recycled). They are blocks with high thermal insulation suitable for the construction of external load-bearing walls with excellent performance: fire resistance, seismic resistance and energy efficiency. The supporting formwork blocks are laid dry: on each row the horizontal reinforcement is inserted into the appropriate lunettes, up to a height of 6 row (1.5 metres). At this point the walls are completely filled with concrete. The vertical reinforcement is always inserted in conjunction with the concrete casting. This type of block is standard and therefore ready for delivery. REI 120 fire resistance – Reaction to fire B, s1-d0 – facade fire reaction (Lepir2 test) Acoustic insulation in class I- Energy class NZEB/ZEB (0 emissions).
