A pressed board of polyester fibers, based on synthetic resins, with a black layer of sandwich interlining.

Features

• sound attenuation up to 16 dB under tiles and ceramic tiles
• to reduce stress on critical substrates (e.g. old wooden floors)
• improves thermal insulation
• resistant to decay
• for service loads up to 3 kN / m ²
• very low VOC emissions

Application

• on the floors
• when laying stairs in multi-storey residential buildings and on insufficiently insulated substrates
• additional thermal insulation for electric heating mats
• a stiffening and stress-reducing layer in the renovation of old wooden substrates or ceramic cladding
• under ceramic and stone tiles
• under parquet, laminate, carpet, PVC
• stress compensation on fresh, shrink-prone concrete surfaces
• Stress compensation on screeds at risk of cracking or on mixed substrates
• improvement of thermal insulation with poorly insulated screeds or on composite screeds
• a layer of thermal insulation when renovating the above-mentioned rooms
• as a cut-off system for laying tiles and slabs in rooms in the EK-WS, EK-GS, EK-HS categories in accordance with the ZDB / euroFEN guidelines
