Floor Solution 1
Acoustic mineral wool and acoustic membrane
If you wish to buy this solution online we can calculate the materials you need.
For a highly effective method of floor soundproofing against airborne sound we would recommend the following system. It incorporates acoustic mineral wool, and high density acoustic plasterboard below the floor boards and a layer of acoustic membrane. Typically the incorporation of the membrane hanging between the joists can uplift the airborne soundproofing by 6-8 db in addition to the other materials. Gaps should be sealed between the floor boards using acoustic mastic. The floor will now have five layers of protection. Ceiling, Acoustic mineral wool, 12.5m SoundBloc, acoustic membrane, and sealed floor boards.
In a situation where you raise the floor boards the above solution provides excellent results for the transmission of airborne sound coming from below.
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.
