Closed-Cell Polyurethane Foam

Closed-cell polyurethane R thermal resistance: approximately 4.7-5.2/10 cm.
Application: outdoor and indoor walls, ceilings, roofs, foundations, window installation
Closed-cell foam is characteristic of twice higher thermal resistance in comparison to cheaper insulation materials such as mineral wool, cellulose, polystyrene, or open-cell foam.
Low thermal conductivity of this foam enables saving the useful space, because the thermal insulation layer can be twice thinner in comparison to heat-insulation using alternative heat-insulation materials. If sprayed on correctly, it ensures excellent tightness, moreover, it does not absorb moisture and can serve as moisture and vapour insulator. Thanks to high density, closed-cell foam adds structural strength to walls or roof. This foam is particularly useful for insulation of complex structural units, joist junctures, roof and overlay joints.
