This is a superb acoustic floor system designed to reduce both the impact and airborne noise transfer through floors. Adapted from an industrial product that was originally designed to greatly reduce the sound transfer of plant machinery noise through floors.

Probably one of the most environmental composite flooring products available. Made from 100% recycled PVC polymers and recycled foam. This makes the product 'greener' and reduces the amount of material going to landfill and is 100% manufactured in the UK. Unlike inferior low quality 'copies' imported from China, the laminate is firmly and uniformly bonded together, the sheets are die cut for easy installation and it does not give off toxic fumes.

The virgin PVC has a low carbon footprint and can be melted and reformed. It is sourced from the chlorine found in common salt and extracted fractions from oil. For every tonne of PVC polymer over half (57%) will have chlorine derived from an abundant source: seawater. The dependence of PVC on the non-renewable resource of oil based derivatives is considerably less than most other polymers used for this type of insulation product.

General Physical Data
Sheet Size 1200mm x 1000mm
Thickness 15mm
Weight Approx. 16Kg/m²
          Foam (FMVSS 302) - Self-Extinguishing
          Barrier (FMVSS 302) - Self-Extinguishing


Carbon Footprint

PVC is a proven material with minimal environmental load in terms of CO2 emissions. Studies have shown that the energy used to produce this PVC compared to other major polymers uses typically 20% less energy.

The laminated composition provides maximum performance for minimum thickness and combines excellent sound insulation with all the qualities of a good carpet underlay. It is quick and easy to install and is easily cut and shaped. Overall thickness is just 15mm so it minimises the increase in floor level.

This product comprises a 10mm layer of chipfoam bonded between 2 layers of 7.5kg/m² mineral loaded acoustic barrier matting. The base layer of barrier mat seals and damps the sound coming through the floor, the isolated top layer of soundproofing mat blocks the sound both ways and the chipfoam core dramatically reduces impact noise transfer.

This product also gives superb performance when used as floating floor isolation under a T&G chipboard wooden topfloor.

Before laying Quietfloor you should examine the existing floorboards and firmly secure any that are loose. It would also be wise to replace any sections that are damaged or broken. It can also be beneficial to seal the gaps between the floorboards and overlay with Tecsound Acoustic Membrane for improved performance first.


Quietfloor can be simply laid, or bonded, to the floor. It is essential that the sheets are laid in a staggered, brick type pattern, and that they are butted tightly together, and up to the perimeters of the room. Due to the 15mm thickness it is best to first run a 9mm thick timber batten, the same width as the grippers (about 25-30mm wide), around the room perimeter. The grippers can then be nailed into this raised batten.

Please note: If your subfloor is not level then you will need to bond the sheets down to prevent any subsequent lifting due to bowed flooring. In older properties even if you have leveled out a floor using chipboard it is still possible that the small irregularities are dealt with but the overall floor may rise and fall in line with the old joists. Small sheet material may want to 'lift' in certain areas if it is not bonded down.
