Polyethylene insulation is presented in the company’s assortment under the brand name Stenophone 290. This is a rolled material based on extrusion foamed polyethylene with a density of 35 kg/m3-40 kg/m3. The structure has an even fine-mesh structure with a closed pore. The color of the material is BLUE. Thanks to a special foamer and increased density, the material acquires unique physical, mechanical, thermal, and acoustic properties.

«STENTOFON 290″ is a unique material for its acoustic properties, which makes it irreplaceable in the production of “floating screeds» in the residential and industrial premises construction. The main indicators for the calculation of «floating screeds» are the index of improvement of impact noise insulation, the dynamic modulus of elasticity and the material durability when used under a layer of concrete.
