LIGHTWEIGHT, DRYING AND SHRINKAGE CONTROLLED, INSULATING SCREED. SUITABLE TO TAKE ALL TYPES OF ADHESIVE AND FLOATING FLOORING.
Latermix Forte is a bagged pre-mixed lightweight insulating mortar of semi-dry “damp soil” consistency for internal use as a screed, and is based on special Laterlite Plus hydrophobic expanded clay, and is ready for use after mixing with only water.
For all types of flooring: Its special formulation gives controlled drying times for moisture-sensitive finishes, and permits any type of flooring to be applied.
Ideal for large surfaces: Its extremely low shrinkage enables large areas to be laid without joints (up to 100 m2).
Lightweight: It weighs approximately half as much as a traditional or flowing screed (approx. 1.050 Kg/m3 when laid). It reduces dead loading and is particularly suitable for reconstructing existing floors and roofs or to prevent excessive loading in seismic zones.
Strong, stable, durable, and CE-marked: It has high compressive strength (16 MPa), is CE-marked to denote conformity to EN 13813 (screed materials and floor screeds), is dimensionally stable and non-deformable, and retains its properties unaltered over time.
Insulating characteristics: Because it is 6 times more insulating than traditional or flowing screeds (? =0.258 W/mK) it improves the thermal resistance of floor and roof slabs and reduces thermal bridging. Its porosity improves acoustic insulation, including in association with specific resilient layers (see impact sound, Calestop: P 21).
Non-combustible and fire-resistant: This is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is fire-resistant and safe, including in the presence of fire.
Suitable for sustainable construction: Its use of natural raw materials, its manufacturing process, which respects the environment, and the absence of harmful emissions (even in the presence of fire), make it suitable for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.
