Silent Floor Ultra Acoustic Underlay - 200 Sheets - 144sqm

Dimensions - 1200mm x 600mm x 11mm thick - 200 sheets on a pallet covering a total area of 144sqm

The Advanced Acoustics Silent Floor Ultra has gone through many months of development to improve on the already effective Quiet Floor Plus.  However that hard work has now paid off.  The Advanced Acoustics Silent Floor Ultra Underlay is more effective, thinner and cheaper than QuietFloor Plus and other similar products.

Silent Floor Ultra is an acoustic underlay which will reduce both airborne noise and impact noise.  We have used the already very popular 2mm thick Soundproofing Mat as the core layer to help with reducing airborne noise.  Impact noise is reduced by use of a 25kg/m3 closed cell cross linked PE foam.  The benefit of this foam as opposed to the reconstituted foam used in other acoustic unerlays is that is will not breakdown and crumble over time.  The foam we have used in this acoustic underlay is hardwearing and yet still comfortable to walk on.  Additionally the foam as well as the sound barrier mat is completely recycleable and free from lead and bitumen.  Because it is safe to dispose of it poses fewer environmental risks and has a higher potential for recycling.  Also because the materials we have selected are durable it has a very long life span which means you won't have to replace it as often as you would other acoustic underlays.

The Silent Floor Ultra is the quickest and most effective means of reducing airborne noise and impact noise for floors.  It is very simple and quick to lay which means labour costs are greatly reduced and is simple enough to lay even if you only have basic DIY skills.  By using this product instead of regular underlay traffic noise from above is virtually elimated when used in conjuction with carpet. You will find a lot of acoustic underlays using two layers of soundproofing mat, one of the top and one on the bottom but during the development of this product we found that reduction in impact noise is greatly affected.  However performance is improved by removing the top layer of soundproofing mat and instead installing a layer of our 2mm soundproofing mat before fitting this Silent Floor Ultra Acoustic Underlay.  Of course if you prefer you can just lay this product straight on top of your floor ready for the carpet or laminate floor to be fitted.

The Silent Floor Ultra is just 11mm thick and weighs 3.75kg per sheet.
