Soundproofing a Home Theater Using Green Glue Or Mass Loaded Vinyl
In the past the best way to construct a home studio or a home theater was to build new wall inside the present room and then construct what is called a “Room inside a room.” Though this technique of soundproofing is yet quite effective, it is expensive and takes plenty of wall space in your theater room that is already cramped.
A better proposal is working with your present walls by adding a fresh drywall layer to the existing ceiling and walls by applying a coating of a product named Green Glue on the fresh drywall and sandwiching it amid the present wall and the fresh drywall. If this is done to all the ceilings and walls you have made significant progress in soundproofing a great home theater. Suppose the location of your home theater is on a second floor, now the ceiling becomes less of a worry and the floors develop into more of a problem. Soundproofing of floors can be done in several diverse ways based on what the completed floor will be installed. Suppose you are planning to have pad and carpet for the completed floor in your theater, subsequently an underlay for soundproof floor would be in place.
Your home theater could have other concerns such as windows and doors. For a minute let us talk about doors; suppose you are attempting to play the movie in the home theater, subsequently a door with hollow core may perhaps be your worst enemy. Majority of present doors in bedroom are hollow core and do not do much about soundproofing. The best bet would be purchasing a solid wood door or solid core MDF. You may add an automatic drop down seal to the base of the door and also a seal kit for door perimeter to seal around the door where it gets closed into the jamb. The cost of an actual soundproof door could be in thousands, with careful planning and a little time; the same results can be got at 1/4 the cost.
The final thing we have to talk about your home theater are the windows. Suppose neighbors are a worry, then it is recommended to build window plugs using the 2 inches vinyl nitrile foam mat of closed cell. For instance, suppose your window were 3 feet X 3 feet, the foam has to be cut to 3 feet 1 inch X 3 feet 1 inch hence giving the window plug an extra ½ inch around it’s full perimeter. This additional ½ inch will assist to hold the window plug firmly into the frame of window much similar to a cork in a bottle. Suppose the window is 4 feet or more on any dimension, it is recommended that you glue the window plug to a backer board.
