Bronze cavity soundproofing system between floor joists and ceiling joists...

Go to bottom of page to order

This Bronze Floor Cavity Soundproofing System is designed to improve the sound insulation of timber suspended floors and not concrete floors. It is particularly useful if no increase in the existing floor height is required and will help reduce airborne noise from above and below. The system is also a very good prelude to further soundproofing on the floor or ceiling to enhance the soundproofing properties of the upgraded floor.

This system is unlikely to reduce any footfall or impact sound that is made on the floor.

The main products used are our excellent soundproofing products SoundBlocker Membrane and our AMW type Acoustic Mineral Wool installed as a sandwich (See Below).

SoundBlocker Membrane

Acoustic Membrane as used in the Bronze Floor Cavity System

This innovative material utilises the latest technology incorporating synthetic rubber and special fillers producing a revolutionary sound blocking membrane.

The product is nominally 1mm thick and weighs just 2Kg/ m².

Acoustic Mineral Wool

The AMW Acoustic Mineral Wool is produced to a specific density to give the best sound absorbing performance. . AMW is used extensively in buildings and throughout industry to give additional acoustic, thermal and fire insulation between floor joists and cavities of stud partitons. It is particularly useful as part of any soundproofing upgrade to assist in the reduction of airborne sound.

It is non-flammable, chemically inert and not adversely affected by any normal substance. 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 the fibres resist 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 and 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 - (12m x 1.25m and 1mm thick) per roll

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 street address (Access Permitting) with full step by step install instructions.

This system is effective at reducing normal noise levels, that should not normally be heard, for example talking and radio at normal sound levels. We suggest you also use a suitable system on top of the floorboards as well. Loud music and bass noise will always be audible although its intensity should be reduced.

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.
