Polystyrene formwork block B-HI40/12+24

for wallfor floorinsulating

The Hi Fixolite range meets the most stringent standards for external thermal insulation (ITE), with a thermal resistance of up to 11. The block complies with the RE2020 and passive houses and BEPOS. Technical specifications Thermal performance: R from 5.26 to 11.11 m².K/W U from 0.19 to 0.09 W/m².K (calculation of the block without concrete and without rendering or facing) Thermal insulation Lambda wood-cement: 1.104 W/m².K Lambda graphite polystyrene: 0.031 W/m².K Sound absorption > 90 % between 100 and 5000 Hz Acoustic insulation -50 dB - 20 cm plastered wall with 12 cm concrete shell -56 dB - 25 cm plastered wall with 16 cm concrete shell Flexural strength ~ 200 DaN (wall not filled with concrete) Fire resistance > 6 hours according to ISO 834 Fire classification Non-flammable, classified M1 Rot-proof Yes Dimensions Width 50 cm Height 25 cm Depth from 35 to 50 cm Concrete veil 12 or 14 cm (or more on request) Polystyrene from 17 to 34 cm Insulation with invert Place the blocks with the insulation protruding above the floor slab. To avoid thermal bridges, extend the Fixolite insulation at invert level with XPS panels. Fixolite blocks can be buried in the ground. Always place a waterproofing membrane (elastomer) in front of the blocks and the XPS insulation, possibly lined with a honeycombed drainage membrane.
