controlling sound leakage with icynene

Sound travels through buildings via the air within the building or the building fabric itself – or sometimes both. People talking in an adjacent room, flat above, outside traffic or loud music being played is sound being carried through the air. If you stop air leakage you reduce the sound transmission through that air. Icynene has excellent air sealing properties and therefore reduces air borne sound. Impact noise is different – when a door is slammed or children are running about above you then this sound is transferred through the building fabric itself  – this is a much harder problem to solve.

Icynene is used extensively as an acoustic insulation for the construction of home cinemas, music rooms, playrooms and day to day living. Every home now a days likes their own quiet space. If you are building a new house, consideration should be given to insulating soil waste pipes to avoid hearing toilets being flushed.

In 2016 JSJ was approached by a member of The Scottish Parliament. We were asked to be involved in a pilot scheme to reduce the noise within people’s properties due to airplanes flying above. Sound testing was professionally carried out before and after we insulated in between the rafters in the roof using 125mm of Icynene’s open cell spray foam. You will see from the report (attached) that the Decibel’s where reduced by 13db. This was a fantastic result for the homeowner, who now lives comfortable within her home.

Please find attached some other sound testing reports carried out by Icynene.

It’s important to note that you are aiming for sound reduction to a level which is acceptable to you, not complete sound proofing, which is very costly and difficult, if not impossible to achieve.

We have many customers who will be happy to verify that Icynene has helped with sound reduction.
