Product Description

Visco 17 high performance acoustic floor panels are ideal for renovations. Unlike Visco 400 or 600, theseoverlay boards can be used when there is an existing sub-floor or when there is need to increase the hieght of the sub-floor.

Visco 17 overlay boards comprise of 4 individual elements; MR MDF, Visco elastic strips, fibreboard and chipfoam. Each element plays a key role in its high acoustic performance, for example the elastic strips dampen the sound vibrations before they reach the building, reducing any airborne noise.

When testing Visco 17 in a complete flooring system including 22mm chipboard deck, 225mm solid wood joists and resilient bars,  it has been deemed fit to satisfy requirements of Approved Document E.

Visco 17 is an extremely versatile product in terms of floor finishes, for example the floor panels can be used in conjunction with carpet, tiling or wooden floors, however there are some floors that require more attention than others; for example when applying vinyl to the acoustic floor panels, 6mm plywood or hardboard should be overlaid before the flooring to prevent mirroring of the joists.


• Excellent Impact and Airborne sound performance
• Low profile and high density versions available
• T&G edge profile for ease of installation
• Laid directly on the sub-floor
• Can be used with most floor finishes



The soundproofing ratings of this product are 55dB impact and 49dB airborne.

These figures aren’t a measure of the reduction that the product gives, but is the figure that you would get following a soundproofing test after fitting, on the same or a similar full floor set-up to the one used during testing (not just the product in isolation).

Please see the product specification for more details on how these figures were achieved.
