AKUFLEX is a sound-insulating substrate based on polyester fiber, which is perfect for finishing (laminate, parquet, linoleum), and especially for "floating floors".
To install this substrate, it is enough to have construction tape and reinforced plastic film.
Dimensions: 1x15m. The thickness is 4mm.
Specifications:
- Surface density: 300 g/m2
- Breaking load in length and width: not less than 750 N
- Thermal conductivity coefficient (λ), W/m S: 0.036
Impact noise reduction:
- under the parquet board 15 mm: ΔLn,w=17 dB
- under the laminate with a thickness of 8 mm: ΔLn,w=20 dB
- under a cement-sand screed with a surface density of 120 kg/m2 with a separating layer: ΔLnw = 27 dB
- under a cement-sand screed with a surface density of 120 kg/m2 without a separating layer: ΔLnw = 24 dB
- under a 20 mm thick KNAUF floor element with 8 mm thick ceramic tiles laid on top: ΔLnw = 21 dB
