Adding acoustic wall insulation to drywall can be a rather demanding process if you are not acquainted with the basics of this niche. Consider the tips below as you tackle this project.
Acoustic Wall Insulation Choice
A common method of soundproofing existing drywall is blowing insulation material into cavities. To do this, holes need to be created in the drywall for inserting the insulation material. The other method is to use acoustical foam. Here, the foam material is secured beneath the drywall panels.
Choose a method that is best suited to your requirements. Soundproofing with blown insulation material is a bit faster, less demanding but more expensive.
Cutting into Drywall
To disengage sections of the drywall, use a pry bar and hammer. Don’t throw away the drywall screws or studs as they can be used later. Use a vacuum cleaner to remove the drywall debris before inserting the sound insulation material.
Take Care Around Demanding Wall Sections
Before starting the project, remove the electrical covers, any light switches, wall decorations and other items attached to the drywall. When cutting the drywall around the electric boxes or underlying pipes, use a smaller cutting tool like utility knife to carefully carve without damaging the surrounding drywall surface.
Acoustic Material Quality
Ensure that the acoustic insulation panels are not moist at the time of delivery. If you are using blown insulation material, choose a reputed brand since this material is quite expensive.
Use Sufficient Soundproofing Material
The acoustic panels should fit snugly within the wall cavity but without exerting too much pressure on the drywall. The blown insulation material volume should be approximated as per the manufacturer’s recommendation since these materials have quite specific performance parameters.
Ensure that there are no gaps or cavities in the drywall expect the ones you make for inserting the chosen insulation material. Use acoustic caulk to cover all drywall cavities. Ensure that you spackle the drywall joints, particularly over the screw-heads. You can sand the spackled areas later to smoothen the wall’s surface.
