What are the pros and cons of various 3/4 inch wood subfloors over joist spaced 16 oc?
Years ago I helped to build a house with straight up 3/4 plywood. It was covered with 5/8 inch partical board also. Never had a squeak or bounce or springiness anywhere.
Today it seems everyone is talking about T&G plywood. Why? Is it really necessary?
Then people talk about Advantec (spelling). I understand it is a protection against water during construction. Is that necessary if you are not building under very rainy conditions? Is it T&G as well? What is a rought estimate of cost differentials here?
