THERMAL INSULATION AND WATERPROOFING

The PU foam is suitable for sealing against moisture or water. Its applications range from construction through foundations pools up roof waterproofing.

The polyurethane ( PU) foam is an extraordinary efficient heat insulation material , which can also be used as a seal. Due to its closed cell structure throughout the cross-section water-resistant and rot-proof, so it can also be used simultaneously as a waterproofing layer and insulation. The foam can be applied directly to gravel pebbles or foil and on the hardened concrete surface equal . The result is a fully enclosed tub with two functions, insulation and waterproofing.

Pitched roofs usually have the requirement to install a moisture barrier. This usually is a special film, which the moisture out and is vapor permeable from below. The closed cell structure of the PU in situ foam ensures continuous surface, which meets this requirement perfectly . This structure also functions as a vapor barrier. One can dispense with auxiliary barrier installation.
