15mm DBX PRO Acoustic Board
Tecsound 100 membrane layer
Resilient tape for perimeter isolation
This system is designed for floors where you need a dense, stable acoustic board build-up above an existing timber floor structure.
Helps reduce airborne noise
Helps reduce impact noise
Improves mass and floor isolation
The combination of acoustic board, membrane and insulation helps reduce sound transfer through the floor construction.

This solution is best used as a complete system rather than as individual products used in isolation.
Acoustic performance can vary depending on the existing floor construction, joist depth, gaps, flanking paths and installation quality. For best results, all boards, membranes and perimeter junctions should be fitted carefully with minimal gaps.
The DBX Board floor system works by adding mass, damping and isolation to the floor build-up. Rockwool RW3 100mm is fitted between the joists to reduce resonance within the floor void. Tecsound 100 Non-Adhesive Membrane is then used as a dense acoustic layer over the existing floor.
The 15mm DBX PRO Acoustic Board creates a strong finishing layer above the membrane, helping reduce sound transfer through the floor. Resilient Tape 50mm is used around key contact points and perimeters to help reduce rigid connections where vibration can pass through.
This system can be upgraded by combining it with ceiling soundproofing below, especially where noise is travelling through the full floor and ceiling structure.
For higher performance, consider treating the ceiling beneath with a resilient bar or resilient clip ceiling system. This helps create separation below the joists and can improve results where airborne noise, footsteps or vibration are still noticeable.
The DBX Board system is suitable for timber floors where you want to reduce sound transfer from above to below, or improve acoustic performance between rooms, flats or office spaces.
It is commonly used in bedrooms, living spaces, rental properties, flats, offices and other areas where sound is travelling through an existing floor structure.
Start by exposing the floor area and checking the condition of the existing floorboards or deck. Rockwool RW3 should be fitted neatly between the joists, with gaps avoided where possible.
Lay the Tecsound 100 membrane over the existing floor surface, keeping joints tight. Apply resilient tape where required around the perimeter and contact points, then install the DBX PRO Acoustic Board over the top. Boards should be fitted tightly and staggered where possible to reduce weak points.

Contact usSound can still travel through adjoining walls, especially in terraced houses, flats and rooms that share a party wall. Wall soundproofing can help complete the room treatment.
If noise is travelling between floors, the ceiling below may also need treatment. Ceiling systems can help reduce airborne sound, impact noise and vibration transfer.
The DBX Board floor system is a floor soundproofing build-up that combines 15mm DBX PRO Acoustic Board, Tecsound 100 Non-Adhesive Membrane, Rockwool RW3 100mm and resilient tape.
It is designed to add acoustic mass and reduce sound transfer through timber floor structures.
Yes, this system can help reduce impact noise such as footsteps, movement and general floor vibration.
Impact performance depends on the existing floor construction, how the products are installed and whether sound is also travelling through walls or ceilings.
Yes, the combination of Rockwool, Tecsound and DBX PRO board helps add mass and absorption, which can reduce airborne noise such as voices, TV noise and music.
For stronger airborne performance, the ceiling below may also need to be considered.
Rockwool RW3 is used between the joists to reduce resonance inside the floor cavity.
It is an important part of the full system and should be fitted neatly between joists where the floor void is accessible.
Tecsound 100 is a dense acoustic membrane used to add mass to the floor system without adding a large amount of extra build-up height.
It sits beneath the DBX PRO Acoustic Board as part of the acoustic floor build-up.
Yes, this can be used as a floor-only system, but the final result depends on the property and where the sound is travelling.
If noise is also moving through walls, ceilings or structural junctions, those areas may need to be considered as part of the full soundproofing plan.
