Laterlite CENTROSTORICO SOTTOFONDO LEGGERO NHL

Sottofondo Leggero NHL is the light and insulating underlay based on pure NHL 3.‎5 natural hydraulic lime, pre-measured with Lecapiù expanded clay (with moisture absorption of about 1% at 30'), particularly suitable for interventions on buildings of historical and artistic interest and for applications in Biobuilding.‎ CentroStorico Calce underlay is light (approximately 700 kg/m³), insulating (conductivity λ of 0.‎18 W/mk) and resistant (average compressive strength > 2 N/mm² at 28 days.‎) and is the ideal subfloor for lightening layers, even thick fillings for vaults and vaulting and for subfloors of any type of flooring.‎ ADVANTAGES Natural and eco-friendly Sottofondo CentroStorico Calce is made exclusively with pure natural NHL 3.‎5 lime and Lecapiù expanded clay: the ultimate in naturalness and sustainability, certified by ANAB-ICEA for Bioarchitecture.‎ It is the ideal product for environmentally friendly interventions on buildings of historical and artistic interest.‎ Lightweight Only 700 kg/m³ in place, it ensures low permanent loads even in large thicknesses, thus lightening structures.‎ Resistant It has good compressive strength (>20 kg/cm²), making it suitable for a wide range of uses.‎ Thermal insulation The low thermal conductivity (0.‎18 W/mK) provides good thermal insulation and thus energy savings.‎ Manoeuvrable and versatile Pre-dosed, it only requires the addition of water: the small sack size of 24 L (approx.‎ 15 kg) ensures practical handling even on the most difficult building sites.‎ FIELDS OF USE Natural product based on pure NHL hydraulic lime, particularly suitable for interventions on buildings of historical and artistic interest as well as for eco-friendly interventions in Green Building.‎ Thick fillings of vaults, vaults and old structures.‎ Insulation-levelling underlays for any type of flooring (particularly suitable for wood).‎
