Heat loss through floors makes 20% of total heat loss rate, in case thermal insulation is poor or missing. TEPLEX material is used for thermal insulation of cold basements, slab-on-grade and heated floors. Basic requirements to insulating material at this construction stage are the following: static and dynamic overload immunity, high water repellency and heat loss resistance. A crucially relevant point here is that the ceiling height can be significantly increased by means of insulating layer thickness reduction.

Extruded foam polystyrene is laid directly on concrete floors and thus, there is no need to involve a waterproofing course in floor thermal insulation above cold basements, guard spaces and passageways. It helps cut down on expenses and reduce amount of works to be completed. However, joint matching of concrete and insulating boards should be avoided for better thermal insulation effect.

Slab-on-grade thermal insulation requires waterproofing. In this case, TEPLEX material is laid on concrete bed or sand mattress. A shiplap edge type of the board helps increase insulating properties of TEPLEX material.

The primary purpose of TEPLEX material application in thermal insulation of heated floors is elimination of heat flow towards underlying units. In addition, in rooms with higher moisture level, waterproofing is essential for heating units’ protection.
