Product information
Karma Visco 21 overlay boards are high-performance acoustic floor panels which provide exceptional acoustic performance. They are particularly suited towards renovation projects which already have an existing subfloor or floor joists in place, with requirements for acoustic performance and additional floor height.
Karma Visco 21 overlay boards are comprised 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 21 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 21 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 that other for example when applying vinyl to the acoustic floor panels the panels should be overlaid with 6mm plywood or hardboard to prevent mirroring of the joists.
• Excellent Impact and Airborne sound performance

• T&G edge profile for ease of installation

- Delivered on a pallet Flooring is heavy, so it comes palletised to the kerbside. You’ll need to move it from the roadside into the property.
- We confirm the day Choose a delivery date at checkout, or we’ll give you the earliest. It’s an estimate until we confirm it once your order is processed, and we can’t guarantee it even then: deliveries are made by third-party couriers.
- Check before you sign Someone needs to be in to sign for it. Look over the packs first and tell us within 24 hours if anything is damaged.
- Book your fitter afterwards Wait until your flooring has arrived before booking a fitter. We can’t cover fitter costs if a delivery is held up.

Rating
The soundproofing ratings of this product are 56dB 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. You can also read more about decibel ratings here.
