Concrete floor impact results

Due to the high mass of concrete flooring, acoustic underlays are only used to reduce impact noise.

200mm Concrete flooring

Without soundproofing 79dB

With 9mm Acoustic Underlay 54dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear. Decibels explained.

• Laid directly over the existing sub-floor
• Loose laid no requirement to bond to the floor. Part E requires bonding for new builds and conversions.
• Butt the edges together
• Reduce movement with High Tack Tape along the joins
• Cut to size using a sharp knife or a fine toothsaw

Carpet as the floor finish

Acoustic underlays can be used directly below the carpet. When installing the underlay, you should consider using the perimeter edging strip to ensure the gripper rods are the same height as the carpet. The gripper rods and the perimeter edging should be nailed to the floor using a 30mm nail.

Hard floor finishes equal to or less than 14mm

Hard floor finishes, including laminate, engineered, and tiles, should use a resilient layer between the soundproofing and the floor finish. We recommend 9mm MDF T&G interlocking sheets. The layers are secured using a floor-grade adhesive such as Isobond floor adhesive. To prevent potential flanking sound from transmitting from the floor to the walls, isolate the flooring using isolation tape fixed to the wall.

Hard floor finishes over 14mm

Floor finishes over 15mm can be installed directly on the soundproof mats. Secure the flooring using the Isobond adhesive. Isolate the flooring using isolation tape fixed to the wall to prevent potential flanking sound from transmitting from the floor to the walls.
