Descripción
weberfloor LIGHT ESTRUCTURAL is a lightweight, insulating mortar for deep screeds, formulated with expanded clay, hydraulic binders, and additives, specially designed for screeds and toppings in both new construction and renovation projects. Thanks to its reduced weight, it is ideal for floor slabs with structural limitations, as it reduces dead loads without sacrificing high mechanical strength (25 MPa). Additionally, its low thermal conductivity helps reduce thermal bridges and improve the building's energy efficiency. It is suitable for indoor and outdoor applications, both manual and pump-applied.
FEATURES
