8,5mm DBx PRO Soundproofing Board - Acoustic Panel

Cutting
When cutting the DBx Boards please ensure they are kept flat at all times. This keeps the sand within the boards before taping up.
The DBx Boards can be cut using :
• Utility Knife• Jig Saw (Metal Blades)• Circular Saw
Taping Boards
After cutting the boards , use the DBx tape to reseal the boards before installation.

Walls and Ceilings:
For walls and ceilings DBx Boards should ideally be mounted onto resilient bars or furring channels for best decoupling results. Dry wall screws are recommended
DBx Boards can also be glued to walls with High Grab Contact Spray Adhesive
It is highly recommended to install dBX Pro board in portrait orientation on walls. This will make installation of sockets easier without excess sand lost whn cutting into boards for services.

 

GUIDE TO FITTING FLOOR FINISHES OVER DBX BOARDS

Fitting Solid Wood, Engineered Wood, Parquet, Laminate and Rigid core LVT Floors Directly over DBX Boards.

• All flooring must be fitted and acclimatised as per manufactures instructions
• It is essential to ensure the expansion gap is carefully adhered to, as this is also necessary to prevent the transmission of sound from the wood flooring to the adjoining walls which in turn would transmit flanking noise. This gap is usually 6mm (12mm when floating) around all fixed vertical objects and the whole perimeter of the room. This will ideally be filled with a flexible acoustic sealant.

Mechanical Fixing

• Solid wooden flooring must not be nailed directly to DBX Boards or through to the sub-deck, which would cause a sound bridge. For a secret nail installation, glue 9mm (minimum) plywood, OSB or chipboard on top of DBX Boards with wood flooring glue. Leave a 6mm gap between the sub floor and the walls and any other fixed structures to reduce vibration and flanking noise.
• Fix the timber flooring directly into 9mm top layer only, leaving expansion gaps as per manufacturer’s instructions. Leave a 6mm gap between the flooring and the walls and any other fixed structures.
• The gap at the perimeter can be sealed with flexible acoustic sealant.

Bonding (usually 6mm expansion gap):

• If the installer requires the option of being able to remove the wood flooring at a much later date without damaging the DBX Boards, then a wooden overlay must be laid and Glued to the DBX Boards - 3mm to 6mm thick plywood is common. It is important to leave a 6mm expansion gap around the fixed objects and the whole perimeter of the room.
• For fully stuck wooden flooring, use the wooden flooring adhesive as recommended by the flooring manufacturer which should be spread evenly on the floor with a medium notched trowel, as per the flooring manufacturer’s instructions.
• Always check for an adequate adhesive bond before proceeding.

 Floating Floors

• Flooring suitable for fitting as a floating floor, as per manufacturer’s instructions, should be laid directly over DBX Boards with or without underlay for the best acoustic performance.
• It is important to leave a 6mm - 12mm expansion gap, as recommended by flooring manufacturer, around the fixed objects and the whole perimeter of the room. For laminate use the manufacturers recommended 6mm gap.
• Joint Sealant for Laminate Flooring can be used to permanently protect laminate from moisture effects, if necessary.

Fitting Fully stuck LVT (Luxury Vinyl Tiles) on to DBX Boards

• Lvt can be fully Stuck directly to the Dbx board using the manufacturer's recommended adhesive, Most LVT Manufacturers will recommend a 6mm Flooring Grade Ply to be Glued Directly to the Db board using a high grab adhesive, with the LVT fitted using the manufacturers guideline
• FULLY TESTED WITH F BALL FOR F44, F46, F48 PLUS, F49, F60, F66, F73 PLUS, FIND US IN THE RAG GUIDE.

Fitting Ceramic Tiles Directly over DBX Boards

• It is recommended to use marine ply as your sub floor, if possible.
• If floor height is not an issue it is recommended to lay a Tile Backing Board or  6mm Plyboard over DBX Boards which is glued to the DBX Boards using a grab adhesive. This will protect the DBX Boards should you wish to change the tiles in the future. It is critical to leave at least a 6mm expansion gap between the tile backing board / plywood and any fixed objects, as well as the whole perimeter of the room, and fill the gap with a flexible waterproof sealant, to reduce flanking noise.
• If floor height is an issue, place a 100mm wide fibre glass mesh ‘scrim tape’ over all SBX Boards joints. Then lay the tiles in a thin bed of rapid setting flexible cement-based tile adhesive, suitable for wooden floors. The scrim tape ensures no movement will take place due to vapour in bathrooms and kitchens.

Fitting Ceramic Tiles Directly over DBX Boards in Wet Rooms

• It is recommended to use a minimum of 18mm marine ply as your sub floor, if possible. DBX Boards are moisture resistant, and its performance will not deteriorate in these applications. Do not knock boards tightly together - simply lay lightly butted allowing for minimal expansion.
• In high moisture areas it is important to lay a vapour barrier, or else it is recommended that a Tile Backing Board or a 6mm Marine Plyboard should first be laid and bonded over DBX Boards using a grab adhesive. It is important to leave a 6mm expansion gap between the tile backing board and any fixed objects, as well as the whole perimeter of the room, and fill the gap with a permanently flexible and waterproof sealant, to reduce flanking noise.

Fitting Carpet straight to DBX Boards.

Carpets requiring a separate underlay.

• DBX Boards are not an underlay, a good quality carpet underlay is still required to protect the carpet and DBX Boards.
• Carpet grippers can be bonded to DBX Boards in the same manner as for solid concrete floors; using a rapid set gripper adhesive The nails are hammered through the gripper and into the DBX Boards-. Common carpet gripper nails are insufficient length to pass through the 15mm DBX Boards, but it is the installer’s responsibility to confirm this on site.
• Carpets with a pre-bonded foam or felt underlay, (not using underlay)
• The carpets usually incorporate a thin foam or felt backing, insufficient to spread point pressure load, and therefore require a 3mm to 6mm plywood bonded to DBX Boards prior to fitting the carpet
• The plywood is glued to the DBX Boards leaving a 6mm expansion gap around all fixed objects and the whole perimeter of the room, which can be filled with flexible acoustic sealant.

Fitting Linoleum & Vinyl Directly over DBX Boards

• Linoleum or sheet Vinyl cannot be fitted directly on the surface of DBX Boards.
• For commercial applications use a hard Linoleum and Vinyl subfloor system floating over DBX Boards or a minimum of 6mm plywood bonded to the DBX Boards.
• For domestic applications, bond 3mm to 6mm plywood or similar to the DBX Boards.
• The plywood is Glued to the DBX Boards using a grab adhesive, leaving a 6mm expansion gap around all fixed objects and the whole perimeter of the room, which can be filled with a flexible acoustic sealant.
