Floor Solution 5
Impact Sound - Acoustic Joist Strips Replacing Floor Boards
If your looking to reduce impact sound with minimal floor build up we would recommend acoustic caps over the tops of each joist. This option will keep to a minimum floor height increase it is typically used where a new chipboard deck is being laid over the joists and a resilient layer is required. It is unsuitable under floorboards as it is creating a floating floor.
The Structural advantage of this solution over other floating floor solutions is that can be applied direct to joist as opposed to over the floor boards.
Floor acoustic treatments compared
What do these terms all mean? We compare the following key issues.
1) Floor height gain - How much floor height will rise as a result of soundproofing
2) Labour intensity - How long will the job take? In general lifting all the floor boards will add dramatically to the time required to complete the soundproofing
3) Typical Airborne uplift - This gives you an idea about how much airborne sound your stopping coming up from below ( or from above) TV / Talking that kind of thing. The bigger the number displayed the better the performance.
4) Typical Impact Uplift - This gives you an idea about how much impact ( footfall) sound your stopping going downstairs. The bigger the number displayed the better the performance.
