Specially shaped porous outer surfaces additionally protect against heat loss, protect against moisture and level out substrate irregularities. The insulating tape uses a permanent combination of two thermoplastic materials with different physical and mechanical properties and, in particular, different density and hardness, where at the interface of the plastics there is dispersion and suppression of vibrations. Product use: underlay for floor joists,underlay for masonry, spacer for wooden grate in wooden ceiling construction,underlay for metal structures in G-K drywall system
