Acoustic insulation
The acoustic insulation process can be extremely effective in situations like upper flats in Victorian converted properties where a degree of noise is suffered from the neighbour below, and/or the owners of the top flat wish to minimize the amount of their own noise pollution suffered by their neighbours below.
There are two basic types of sound pollution that can be diminished through sound-proofing, acoustic and impact.
Acoustic insulation helps protect you and your neighbour, from the sound of voices, music and similar noises travelling through the shallow void space between your floor and your neighbour’s ceiling. In Victorian conversions, this type of noise transfer can be a significant issue as these properties were never actually intended to be split into separate dwellings and it was therefore never factored into the construction spec.
Impact sound is the noise from heavy footfall, banging of furniture etc. This is much more involved and expensive to deal with and involves lifting the entire floor as part of the process. In a Victorian conversion, we can help with the former, but to deal with the latter, it is best to employ specialist companies.

The acoustic insulation process
1. Every 5th/6th board lifted. Insulation cut to the width of space between joists.
4. During the feeding in process, we try to pack as much material as possible into the void space. There's no point in skimping on material.
2. Every 5th/6th board lifted. Insulation cut to the width of space between joists.
5. The boards are then re-fixed & we then get on with the sanding & sealing process.
3. It needs to go under all cables & pipes.
