These tips will be of great assistance when you have to patch a big drywall hole
Inspect your walls
To properly maintain your drywall at home or at your business, you have to regularly inspect it or let our experts at Calabasas inspect it for you. You may need to examine the areas where the screws are placed as well as the joints between the sheets. These are the places where dimples and ridges appear.
Pay attention to the noise absorption rating of acoustic insulation
If you plan to use acoustic insulation for soundproofing the walls of your house, our experts recommend that you check the noise absorption rating of the material. It is between zero and one. The higher the rating is, the better you will be protected from noises which come from the outdoor environment.
