Laterlite CENTROSTORICO SOTTOFONDO

Sottofondo CentroStorico is the premixed lightweight underlay with high surface compactness and rapid hardening.‎ It is a subgrade with high compressive strength (70 kg/cm²) and, thanks to its fine grain, creates a closed, compact surface that makes it suitable for even the heaviest applications during subsequent work (formation of plaster, floorboards, partitions).‎ It is ideal for allowing the finishing layer to be laid quickly.‎ With its 650 kg/m² density on site, it ensures low permanent loads by lightening structures.‎ The premixed Sottofondo CentroStorico is certified by ANAB-ICEA for Bioarchitecture.‎ ADVANTAGES Resistant with a closed and compact surface It is a subfloor with a high compressive strength (70 kg/cm²) and, thanks to its fine grain, it creates a closed and compact surface that makes it suitable for even the heaviest uses during subsequent work (formation of plaster, planking, partitioning).‎ Fast hardening Compression-resistant after just 7 days (60 kg/cm²), it is ideal for allowing the finishing layer to be laid quickly.‎ High flatness Thanks to its fluid consistency, it ensures the necessary flatness to the subfloor for laying the acoustic mat and radiant system panels.‎ Thermal insulation The certified low thermal conductivity (0.‎186 W/mK) is synonymous with insulation and therefore energy saving.‎ With only 5 cm, the two-layer substrate in horizontal inter-floor partitions is insulated in accordance with thermal regulations.‎ Lightweight Only 650 kg/m³ when installed, it ensures low permanent loads by lightening structures.‎ In roofing Suitable for direct bonding of bituminous waterproofing membrane.‎ Non-combustible Composed of Lecapiù and cementitious binders, it has a Euroclass A1 (non-combustible) fire rating.‎ Manageable and versatile Pre-mixed, it only requires the addition of water: the small sack size of 25 L (approx.‎ 16 kg) ensures easy handling even on the most difficult building sites.‎ Pumpable With standard pneumatic underfloor pumps.‎ Eco-friendly The premixed Sottofondo CentroStorico is certified by ANAB-ICEA for Bioarchitecture.‎ FIELDS OF USE Insulation layer with high surface compactness and rapid hardening for reduced thickness two-layer substrates.‎ Lightweight single-layer subfloor with fluid consistency for direct laying of floors that are not sensitive to moisture.‎ Insulation-levelling layers for substrates in "heavy" site conditions for subsequent processing (plastering, boarding, etc.‎).‎ Compact, closed-surface compensation layers for the installation of underfloor heating system panels.‎ Thermal insulation layers for slopes (max.‎ approx.‎ 15 %) and roofs suitable for direct laying of the waterproofing membrane.‎
