Discover SILENT STEP ALU, the substrate that ensures sound insulation guaranteeing excellent reaction to fire and respect for the environment.
Thanks to the aluminium coating, it is suitable for use with underfloor heating systems.
As well as offering good soundproofing properties, it acts as a barrier to damp: the aluminium-coating prevents the passage of humidity (SD value > 150 m), protecting the floor. Fire reaction class Bfl - s1.
Compliant with the environmental sustainability parameters laid down by Blauer Engel, the German ecological certification body.
SILENT STEP UNI is chemically stable and does not contain harmful substances or VOCs.

SILENT STEP ALU
Supply and installation of soundproofing and waterproofing self-adhesive bituminous foil, type SILENT STEP ALU
- Thickness [mm] : 2
- Water vapour transmission Sd [m] : >150
Suitable for timber-to-timber installation to create a physical and mechanical separation between the two elements, thus avoiding the transmission of vibrations caused by impact sound. To increase the vibration absorption capacity, it is advisable to install the profile both below and above the timber floor. Install the profile on the upper section of the wall and fix it mechanically with staples every 40/60 cm. Then install the horizontal panel of the floor and repeat the operation.
