Acoustic and Intumescent Sealant 900ml

Acoustic and Intumescent Sealant is an absolute essential for soundproofing. General advice for the majority of soundproofing products, especially with the use of Acoustic Plasterboard, or installing rigid materials, is to leave a 2-5mm gap from the perimeter to reduce ‘Flanking Transmission’, a negative impact of sound taking an alternative route to the direct and ‘obvious’ path, for instance through the wall and not the two adjacent walls. This form of ‘Flanking Transmission’ is where sound passes between two solid materials in contact. Acoustic Sealant acts almost like a putty, meaning that it does not set solid. Acoustic Sealant is also to be used between Acoustic Plasterboard layers to increase the air-tightness of the ‘acoustic barrier’.
