Soundproofing a concrete floor
How to soundproof a concrete floor to ensure sound does not transfer between this type of flooring. Most buildings with a concrete sub-floor have sufficient mass and density to block the transfer of airborne sound. Conversation and TV noise would not normally pass between the floors of buildings that use concrete as the sub-floor. The main noise issue that you would expect for concrete flooring is impact sound. This type of sound would include footfall and movement of objects across the floor.
The best way of soundproofing concrete floors to reduce impact sound is to use a resilient layer over the concrete flooring. The soundproof layer is installed over the concrete and below the floor finish. The type of soundproofing you use to block impact sound through the concrete is made from materials that absorb impact sound before it transmits into the concrete. There are several products available for soundproofing concrete floors. Which you chose is often determined by factors including restrictions on floor height and what the desired floor finish will be. Noisestop Systems have a range of concrete floor soundproofing solutions suitable for use with concrete and precast concrete floors.
Solutions for soundproofing concrete floors
Noisestop Systems provide a range of flooring products suitable for use over concrete flooring. Soundproof membranes and floating floors are the two main floor soundproofing solutions for concrete flooring.
Acoustic membranes for soundproofing concrete floors
Acoustic membranes are normally rolls or sheets of acoustic matting bonded to the sub-floor, this type of solution ranges in thickness from as little as 3mm to 9mm. Thicker Soundproof underlays are available, but they often incorporate airborne noise reduction. A floor constructed from concrete would not normally require additional insulation to reduce airborne noise.
Soundproof a concrete floor with a floating floor
Floating floors consist of membranes bonded to the back of interlocking flooring. This type of product will block impact sound before it transmits into the concrete floor. Install this type of floor without fixing directly to the concrete sub-floor to avoid sound transfer through the fixings.
Reduce flanking sound through concrete flooring
Most buildings constructed using concrete flooring normally have steel and concrete support structures. This type of construction can cause sound to transfer if there is a direct connection between the floor and walls surfaces. It is important to isolate the flooring from the walls to reduce the possibility of flanking sound.
The flanking sound transfer associated with the concrete building travels across the floor and into a wall. The sound can then transfer into other parts of the building. The best way of reducing flanking sound is to isolate the flooring from the walls. Ensure the flooring does not come into direct contact with the wall that forms the room’s perimeter. Using isolation tape around the room’s perimeter will reduce the possibility of impact sound transferring into the wall.
