ISOTEX HB 20 - Формовочная система для несущих стен

The ISOTEX wood concrete formwork block HB 20 is used to build load-bearing interior walls.‎ The block has a total thickness of 20 cm, while the thickness of the concrete casting is 14 cm.‎ The massive structure made up of ISOTEX blocks and slabs, combined with the use of structural concrete, provides excellent sound insulation from both airborne and footfall noise.‎ ISOTEX has reached the highest classification in terms of acoustic insulation (Class I°).‎ For the production of all ISOTEX products, raw materials of absolute quality are used: 100% recycled fir wood, 99% pure Portland cement, iron oxide, water, to obtain a healthy product, free of additives and chemical substances.‎ The wood is mineralised using a natural mineral, which makes it inert and therefore resistant to fire, weathering and pests.‎ Theblocks are laid dry without mortar.‎ For every metre and a half (6 courses of blocks), vertical and horizontal reinforcements are inserted and filled with concrete.‎ With a single, simple and quick operation, a load-bearing wall suitable for seismic areas is obtained, with high thermal and acoustic insulation performance, considerable thermal inertia, good breathability and REI 120 fire resistance.‎ All ISOTEX products meet the CAM requirements necessary to access the PNRR and SUPERBONUS (Ecobonus + Sismabonus) school building incentives, thanks to the ANAB/ICEA Green Building Certification, VOC test and Environmental Product Declaration (EPD/FDES).‎ ADVANTAGES OF THE ISOTEX BUILDING SYSTEM: Anti-seismic safety Fire resistance (REI120 - REI 240) Fire reaction B-s1,d0 Fire behaviour of façade (Lepir2 test) Circular economy and environmental sustainability (CAM) Very low VOC emissions (Indoor Air Comfort and Indoor Air Comfort GOLD) Energy saving Class A4 / NZEB / Emission 0 (ZEB) Sound insulation (Class I°) Excellent thermal inertia Speed of installation Reduced construction costs Ready todeliver material * Calculation of thermal transmittance has been carried out according to the criteria of UNI 10355 and UNI EN ISO 6946, using a three-dimensional finite element calculation programme validated according to EN 10211/1 and based on thermal conductivity data obtained from experimental tests (see website www.‎blocchiisotex.‎com ).‎ ** Indicative two-dimensional calculation according to UNI-TS 13788, UNI 10355 and UNI 10351.‎ *** Note: Test certificates can be requested from ISOTEX or consulted on the website www.‎blocchiisotex.‎com .‎ These are in situ tests whose data were processed according to the indications provided in the new technical standards currently in force (UNI EN ISO 140 series standards and UNI EN ISO 717 series standards).‎ **** Tests carried out in the laboratory with UNI EN ISO 140-3:2006 and UNI EN ISO 717-1:2007 standards.‎ ***** Laboratory tests carried out in accordance with the UNI EN ISO 10140-2:2010 and UNI EN ISO 717-1:2007 standards.‎ ISOTEX FORMWORK BLOCKS COMPLY WITH THE GUIDELINES APPROVED BY THE SUPERIOR LLPP COUNCIL (JULY 2011)
