Osb As Underlayment For Carpet
That would be the cheapest way to do it but not my first choice even with carpet.
Osb as underlayment for carpet. 2nd choice i might be talked into 1 2 osb to keep the price down. Your 7 16 osb is bare bone minimum too flimsy. Get 5 off when you sign up for emails with savings and tips. Please enter in your email address in the following format.
The minimum subfloor thickness is approximately 3 4 inches so the minimum thickness of osb board you will need for laminate flooring is 23 32 inches or 18 mm. The subfloor consists of sheet materials that are nailed or screwed to the joists to. I recommend 1 2 underlayment grade plywood not the cheap cdx sheathing. A typical wood framed residential flooring system is more complicated than you think.
In fact due to the problems that edge swelling creates underneath a finished floor a couple of national ceramic tile associations have discouraged the use of osb as a subfloor or underlayment. An osb sheet has a finely corrugated unfinished side and a smooth side that is often coated with a clear finish.
