Ventilated base floor panels

FINNFOAM is particularly well suited for constructing ventilated base floors, whether using

timber or a hollow-core slab.

FI-K600 (210, 250, and 370 mm) and FL-K600 (210 mm) products are suitable for timber-framed ventilated base floors.

The effectiveness of FINNFOAM insulation panels designed for ventilated base floors is based on high compressive strength and rigidity, which enable the special structure: a single work stage allows you to create the necessary thermal insulation, windproofing, vapor barrier, and casting mold – in just a few minutes. At the same time, you will also construct a sturdy floor surface for worksite use. Today, the ground and interior foundation surfaces within the ventilated base floor should also be thermally insulated using regular FINNFOAM insulation, as this will significantly reduce moisture stress within the base floor.
