yes
Insulation and sheetrock are related only in the sense that they are used in walls. When one side is drywalled insulation batts can be stuffed in the other side and then boarded up.
Some of the water-resistant versions are green on one side.
The combination of heat dried gypsum and strong paper each side gives drywall boards their strength.
Rigid insulation by DOW makes many different types of insulation, most have a foil side which should be glued to the concrete while the colored side with logos on it will face out ready for walls to be framed and sheetrock to be hung.
Usually you cut a hole on the other side of the wall behind the shower. Very often this is in a closet. If not, you can use the piece of sheetrock to make a door or put it back in place and retape the joints.
Typically 16". You'll notice on a tape measure that 16" is highlighted. This is the distance from the side of one stud to the same side of the next stud (e.g. from the left side across the existing stud to the placement of the next one.) The actual void between studs is a little less (14 1/2). This is so sheetrock/plywood falls evenly on the wall.
soap scum sticks to the side of the bathtub witch causes bathtub rings to form.
Not suggested, the exhaust and condensate would end up in the attic. There are air conditioners made for situations such as yours. They just sit on the floor, every once in awhile have to empty the condensate pan though.
Yes, but you might get hurt. Be careful.
No, it's false. Because temperature has nothing to do with diffusion.Diffusion is like this, imagine that you are pouring a water on a bathtub, if you pour the water on one side of the bathtub, the water will still go to the other side of the bathtub and then the water will be leveled inside the bathtub. Therefore no matter what temperature it won't affect the movement of water.
yes,with some duct tape connect them in a standing position the height of the space between top and bottom plate of wall. Make these tubes and stand them in the wall tight against each other, before wall sheetrock or plywood is up(it's easier with one side up to give cans a wall to hold them up). This will create dead air space, and considered one of the best insulators.
Hole the size of a quarter, just fill it with joint compound and sand smooth. Anything up to 12 inches, you can cut out the damage, cut a piece of sheetrock 2 inches bigger in both directions. On the back side, cut through the back paper only 1 inch in all the way around, break off that one inch and peal it off of the front paper. Apply joint compound on the 1 inch flange, set it in the hole and work the mud out around the edge. Finish the top of the whole piece with compound and sand. Anything bigger, go to the studs on either side of the hole, cut down the center of the stud and across to take out the damage and put a new piece in, Put a block of wood behind the rock in the middle of the space. This can be anything, 2x4 or a piece of plywood, screw through the old rock above and below the cut and after you have the piece in place screw it to the same board. It doesn't have to be solid between the studs. Finish the joints as you would any other joint.
