Multi-layer, heat- and noise-insulating floor - comprising concrete base, integral, insulating mortar, and rigid flooring slabs

摘要

A heat- and noise-insulating floor is made by placing an integral (i.e. monolithic, gapless) layer of mortar over concrete floor base, and then laying rigid slabs on top of the still damp mortar. The mortar contains an insulating filler esp. in form of beads of foamed polystyrene or "Perlite" (RTM) and a binder esp. a hydraulic binder. Used in dwellings, factories, schools, hospitals. The insulating layer is free from gaps which may undesirably act as heat- and noise-conductors.
