The sound-absorbing benefits of underfloor insulation

Along with great thermal performance, the Retrovive cellulose-fibre insulation system has excellent acoustic properties.
Our blown-in cellulose-fibre insulation has a high density when installed (around 50 kg/m³). Together with the randomness of the fibre directions, this makes it very effective at absorbing sound.
Using it underneath traditional suspended ground floors makes a very noticeable difference when floorboards are left uncovered, a characteristic that most customers remark on – it is much quieter walking across the room and the atmosphere feels much more calm generally.
In fact, we have also used it in intermediate floors for this benefit, significantly reducing noise between upstairs and downstairs.
We all need a little peace and quiet sometimes - particularly when working from home. Speak with our team today to find out how we can make your living environment more comfortable.
