Does drywall make a room warmer?
Drywall can be an air barrier One way to create a more energy efficient building is to stop air leaks through the thermal envelope. The building envelope separates the conditioned spaces (heated or cooled) from unconditioned spaces (outdoors, attics, crawlspaces, and the ground).
Is sheetrock a good insulator?
Materials that offer better thermal resistance are naturally better insulators than those with lower thermal resistance. Frankly, while drywall is a wonderful material for many reasons, it isn’t much of an insulator.
Is drywall a good air barrier?
Gypsum board drywall is, itself, a suitable air barrier material. The taping of drywall seams results in a plane of airtightness at the field of the wall. However, several steps must be taken to use this material property to create a continuous and complete air barrier system.
How far should drywall be off the floor?
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

How many screws come in a 4×8 sheet of plywood?

Is 7/16 OSB OK for flooring?
Firstly 7/16 is a roof or wall sheathing and is not for flooring. Secondly you have installed the panels with the strength axis parallel to your joist/ceiling joists. OSB stands for Oriented Strand Board and that means the wood strands are laid up so one direction is stronger than the other; the same way plywood is.
