Tecsound – Floor Soundproofing Membrane

Home/Products/Floor Sound Insulation/Tecsound – Floor Soundproofing Membrane

Tecsound is a high density visco-elastic polymer-based, asphalt-free, synthetic soundproofing membrane, that offers good acoustic insulation in different building elements. It has a reinforcing scrim on one side to improve the tear strength of the membrane and at the same time provide a protective finish. Available in 5kg per m² and 10kg per m² options.

Features

  • High acoustic insulation, combined with soft, flexible elements
  • Tecsound 50 weight – 5.0kg per m² @ 2.5mm
  • Tecsound 100 weight – 10kg per m² @ 5.0mm
  • Viscoelastic properties
  • Easy handling and adaptable to uneven surfaces
  • Has protective reinforcement scrim
  • Acts as a vapour control layer
  • Cold and heat resistant
  • Excellent ageing resistance
  • Rotproof

Tecsound is suggested for use as follows

  • Soundproofing against airborne noise in lightweight partition walls
  • Soundproofing against airborne noise in ceilings and lightweight roofs
  • Reduction of impact noise level in all types of floors, sandwiched between floor slabs and loose-laid flooring
  • Damping of impact noise caused by rain or hail on metal decks
  • Insulation of gutter pipes
  • Sound damping of metal sheets
  • Soundproofing of booths and machine-rooms

Substrate: Tecsound lends itself to all types of normal building substrates (renderings, gypsum board, metal, DM, plastic materials). The substrate must be even, smooth, clean and dry. It must also be free from elements that could damage the membrane. If the rendering is old, its condition must be checked to avoid adhesion problems between the Tecsound sheet and the rendering.

Installation of the membrane: When using on a floor it should be loose laid on the floor surface with joints butted together tightly. Prior to installing on a vertical surface membrane, an adhesive should be applied according to the instructions of the adhesive manufacturer before bonding the two surfaces. Pressure must be exerted on all the points to ensure correct adherence. It can also be mechanically fastened. The number of fixings will depend on the product, the support and the system where the membrane will be applied.

Installation of the membrane on metal decks: Extend the roll over the substrate, keeping the reinforcement face up so it protects the membrane. The membrane must be applied in such a way that the length of the roll is perpendicular to the direction of the deck profile. The membrane must be made to follow the profile of the metal support at all times, ensuring that there is no formation of air pockets. The thermal insulation boards are then installed and mechanically fastened.

Laps: Overlap 5 cm both vertically and horizontally. Care must be taken to always seal the laps correctly, as small openings can reduce the level of acoustic insulation required.

Yield: 1 m2 of membrane covers approximately 0.90 m2 of surface area, including overlaps.
