Hey Steve Quick Question

[Hi Def]

Hey Steve, I read your mention of materials that you would use for the ideal floor layers on a control room. It was OSB, MDF then Plywood. Your reasoning was for adaquate support for the walls. Heres my question...I used 7/16 OSB, 5/8 Sheetrock and then another layer of 7/16 OSB. The floor joists are 2x4 floated with insulation overstuffed between. Do you see this combination causing any support problems down the road? While walking around on the floor, its very very solid, doesn't ring and has little to no flex under my 210 pounds! Sorry, just read other topics and it sparked the concern. Thanks.

M, I'm just getting too old to want to do things like this over - for that reason, and because I don't want to recommend anything to people that may cause problems, even 20 years down the road, I tend to stay on the caution side. I've known of several floors built just as you mention, and so far none have had problems.

I'm still not sold on the idea of anything as frangible as gypsum being used as load bearing material, especially a fully floated room and ceiling - if it were me, even if I DID decide on the gypsum core I would stop the gypsum about 6" away from the edge of the floor and continue with something less compressible, such as MDF - for the main portion of the floor, I'm all FOR using an inner layer of gypsum. It's high mass, relatively cheap, easy to trim, and more damped than other wood - I'm just not willing to "bet the farm" on it... Steve
