Soundproofing membrane specially for lightweight slabs
U-Boot® Silence is the sound insulation mantle specifically designed to be used on slabs lightened with the U-Boot® Beton system, which “silences” for good the annoying airborne noise and by impact.

The application of U-Boot® Silence on these lightened slabs delivers excellent insulation performance by placing the building into Class I (UNI 11367:2010) for the airborne noise and impact.

In recent years the awareness of home comfort has become increasingly widespread. Developers and end users require outstanding performance and quality characteristics, appropriate to their expectations and demand specific warranties from the manufacturer and the designer.

While on the subject of energy saving leaps and bounds have been made in recent years, the problem of acoustic comfort is still underestimated. Recent studies have also shown that people who live in areas not adequately insulated acoustically have trouble sleeping, irritability, reduced productivity at work.
For these reasons, non-compliance with minimum noise insulation performance may compromise the very validity of the certificate of habitability and produce a considerable loss of property value.

ADVANTAGES

  • Excellent performance of sound insulation from airborne and impact noise.
  • Acoustic requirements exceeded minimum DPCM of 12.05.97
  • Classification of the building in Class I (UNI 11367:2010) for airborne and impact noise.
  • Excellent relationship between mechanical strength and dynamic stiffness.
  • Guarantee of durability.
  • Cheap, quick and easy to install.
  • Great elasticity and dimensional stability even under permanent loads.
  • High capacity for shock absorption.
  • Strong resistance to abrasions and lacerations.
  • Waterproof, rot proof and resistant to microorganisms.
  • Excellent resistance to foot traffic and perforation.

U-Boot® Silence Laboratory Tests

Empirical evidence on the level of sound insulation have been obtained by laboratory tests, carried out according to UNI EN ISO 1403:2006, 140-6:2000, 717-1:2007, 717-2:2007 standards, on a plate slab lightened with the construction system U-Boot® Beton.
The results of unfinished slabs, are better than traditional masonry systems both in terms of airborne noise and by impact.
Even more important is the outcome of the acoustic tests of the slabs lightened with U-Boot® Beton on which was created a floating floor with a soundproofing mantle U-Boot® Silence, which showed values ​​corresponding to Class I .(UNI 11367:2010)

U-Boot® Silence is made of 100% closed cell polyethylene, density 35 kg/m3, low elastic module. The mantle is yellow, with a smooth surface.
The chemical cross-linking gives it a particular elastic structure, which is essential for optimum sound insulation.
The unique mechanical properties make it suitable for medium loads different elasticity depending on the weight.
