Akufloor-S20

Akufloor-S20 floor soundproofing boards are fabricated from using a special technology from fiberglass with low shrinkage under load and low dynamic modulus of elasticity. Coupled with high mechanical stress resistance, the soundproofing floor structure based on Akufloor-S20 boards is a highly effective single-component floor soundproofing system with protection from impact and airborne noise.

Applications

Akufloor-S20 fiberglass boards for impact noise insulation are used in soundproofing floating floors as a working elastic layer under a leveling concrete or cement-sand screed.

Physical and Technical Properties

• Useful dimensions: 1200 х 600 mm
• Board thickness: 20 mm
• Density: 90 ± 10% kg/m3

Relative compression under load:

• 0,05 at 2000 Pa
• 0,08 at 5000 Pa

Floor structure impact noise reduction index

• at thickness 20 mm – ΔL n,w = 36 dB
• at thickness 40 mm – ΔL n,w = 41 dB

Additional airborne noise insulation index ∆Rw = 10 dB*
