Best Wall Soundproofing Material

Do you live in a noisy neighbourhood? Your next-door neighbours making a racket? Or, you need your walls soundproofed for your music? All these scenarios, require some serious soundproofing.

Below we can examine the best wall soundproofing materials you can use to soundproof your walls and reduce the impact of noise.

Acoustic Soundproofing Sealants

Soundproofing sealants are used as adhesives with other soundproofing materials like acoustic foams and tiles. They double up as soundproofing materials, by covering spaces that might let in noise. Below are two best acoustic soundproof sealants you can use to soundproof your wall:

Like other sealants, the AC50 sealant is a strong adhesive and can be used with other wall soundproofing materials. It can be used to bond wood, plasterboard, and other kinds of insulation boards. They can also be used over cracks and gaps.


  • It is a permanent adhesive. It will hold plasterboards, wood, and the likes, permanently. It will also hold acoustic foams and tiles permanently.
  • It is non-flammable. It is very fire resistant.
  • It can stick to moist surfaces. Water doesn’t affect its capability. It is also water-resistant. It can be used to cover moist cracks and gaps on walls.
  • Being water-resistant, it is also resistant to mildew. Once cured, the sealant can be painted over. Curing involves allowing the sealant to toughen. This might take some hours.


  • The size of the sealant tube is just 380ml. If you plan on doing a lot of work with it, then there are bigger sizes.
