Cellulose insulation is an effective soundproofing element when blown into walls and floors.
- Excellent air-tightness blocks airborne noises
- The randomness of fibres in the insulation dissipates acoustic energy
Used in combination with layers of different materials and air gaps, high sound attenuation is achieved. However, complete sonic separation is almost impossible to attain with insulation alone. Cellulose fibre is most effective in blocking higher frequencies and airborne sounds in comparison to lower frequency sounds and impact noises.
Meeting Sound Regulations
Designers can specify cellulose insulation in a tried-and-tested construction to meet sound resistance regulations. Panels filled with cellulose insulation have achieved certification for Robust Details to satisfy Part E of the Building Regulations.
