The Bronze Floor Cavity System reduces airborne noise
when installed under the floorboards and is particularly useful if any increase in the existing floor height is not desired.
This Bronze Floor Cavity System is designed to improve the sound insulation of timber suspended floors so is not suitable for concrete floors. It is particularly useful if any increase in the existing floor height is not desired and will help reduce airborne noise from above and below. The system is also a very good prelude to further soundproofing that may be required on top of the floor to enhance the soundproofing properties of the insulated floor. This system is unlikely to reduce any footfall or impact sound that is made on the floor.
The main products used are our SoundBlocker Membrane and Acoustic Mineral Wool and installed as a sandwich (See Below).
SoundBlocker Membrane
This innovative material utilises synthetic rubber and special fillers producing a revolutionary acoustic membrane.
This product is only 1.2mm thick and weighs just 2Kg/ m²so it’s easy to handle and carry.
Acoustic Mineral Wool
Our AMW boasts more than twice the density of normal loft insulation and so is very efficient at absorbing noise. Acoustic Mineral Wool (AMW) is used extensively in buildings and throughout industry to give acoustic, thermal and fire insulation. It is particularly useful as a sound absorbing infill for the reduction of airborne sound between flooring joists.
It is non-flammable, chemically inert and is not adversely affected by any substance it may come into contact with. The panels are Zero ODP and Zero GWP in the terms of the code for sustainable homes. Each slab is made from 22 % recycled raw materials.
Random arrangement of fibres ensures no water penetration in any direction. It is rot-proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, moulds or bacteria. It will not react with wired plastic or metal wall ties, brickwork or masonry.
The system is supplied with the following products included;
A layer of SoundBlocker Membrane - (10m x 1.5m and 1.2mm thick) per roll
2 x Layers of Acoustic Mineral Wool - (1200mm x 600mm x 50mm thick) per slab
If you have experience of lifting floorboards then the system will be easy to fit otherwise a local handyman or second fix carpenter could undertake the work.
Once ordered the products are all delivered to your door (Access Permitting) with full step by step install instructions.

PLEASE NOTE: The figures above are based on the whole floor area and do not allow for the joists widths. This may mean the figures quoted for Acoustic Mineral Wool maybe slightly higher than needed and as we don't know many floor joists your floor has the figure given for SoundBlocker Membrane may be not enough as the product goes up and over the joists. We advise you check this yourself before ordering.
We advise to always add a few extra of each product to allow for wastage from offcuts.
Please note: This system is effective at reducing normal noise levels, that should not normally be heard, for example talking, radio sound. We suggest you also use a suitable system on top of the floorboards as well. Music and bass noise will always be audible although its intensity should be reduced.
