AKUFLEX
AKUFLEX is a soundproofing roll material made of polyester fiber, developeed specially for floor soundproofing. Request PriceAKUFLEX material is used as an elastic underlayment under finished floor coverings: laminate, parquet, linoleum, as well as under leveling screed to reduce impact noise under the floor slab in the room below.
The material is approved for use in construction in the Republic of Belarus (TS 05.1836.17) and the Republic of Kazakhstan.
Composition
Polyester fiber treated using a special technology to achieve stable and durable elastic properties.
Distinctive features
- Versatile application: for finishing coatings and leveling screeds;
- Increases the service life of floor coverings by allowing air and moisture to circulate;
- Fibrous structure guarantees stable acoustic performance throughout the entire service life;
- Allows for thin and effective additional impact noise insulation (ΔL'nw = 21 dB) without the need for a leveling screed.
