I believe Robert is looking to replace flooring above the room.įlooring is slightly more perminent. Went on a long vacation & came home two weeks later to find the floors in his house had collapsed into the basement.Īpparently there was also a mess with insurance because of permits & code. Several months, maybe a year after it was finished he noticed things above "slanting". While I didn't see it myself, a drummer I know has a friend who built out a basement room and had a major problem. and more weight on the floor above could lead to serious problems. But using 2 or 3 with other materials in between.
Putting up a single layer of drywall should be fine in most structures. adding mass is adding mass.Īt the VERY least you should check with an architect or master carpenter before doing anything. In other words, it makes the amps quieter but probably won't do squat for foot traffic coming downstairs.Įither way. but it also transfers vibrational energy. Going with hard materials, like tile & MDF as a subfloor sure works for adding mass. like carpet matting or sheetblok to absorb some of the impact. Ideally you'd want to go with something "soft" as a sandwich layer. Look him up on amazon or whatever and you'll see it. Reference: The ultimate book for a beginner and continuing research for me has been Rod Gervais' book. This leads to cracking and shifting later in the life of the floor. This is actually the mark of a good tile guy - you shouldn't be able to tap any of the peices and hear a hollow sound. Just make sure that your tile guy does a good job of putting in the mortar so there are no hollow spots under the tiles. This helps as well, so if you're going to put tile in that room, it would help. You are bringing up another consideration - adding to the mass on the top of the deck/floor. MDF - very dense and good if used as sub flooring. There are varying types of boards like this and if you have an option for something more dense - do it. Note some backing is filled or dispersed with styrofoam to keep the weight down. Tile - with proper wet/wonderboard backing. In terms of being effective in helping with the MASS of the floor, At ready acoustics, I bought 6 panels which were 2" thick for a total of $80. They were easy to put together, and look good. I bought their OC 703 and their DIY ReadyBags. If you are interested in room treatment, most people recommend Owens Corning 703 fiberglass board or Rock Wool. While these products make a room seem "dead", with little echo, they don't do anything for soundproofing. controlling sound reflections within the room. Both of these products can lower your decibles through a wall.Īll the foam stuff people talk about is for room treatment, ie. The other product, which I wish I knew about earlier, is GreenGlue. I drywalled my garage with it, and it works well, but is REALLY expensive. I've only found two drywall products that are easily usable for home. Room treatment and sound proofing often get confused and are two different things.įor soundproofing, besides building a "room within a room", you have to add mass.
