Usually with a piece of insulation fitted between the joist, top of the foundationand the floor.
sit that is the only word i can think of "Don't miss the floor joist and fall all the way into the basement"
it is the board that is put on the top of the basement wall and then the side wall is built above that.adding foam to this joist helps to reduce air infiltration up to 25 percent.
30 degrees
The rim or band joists in the basement are a bad place to insulate because it will cause the floor above to always be cold. Heat rises, and any heat in the basement from the furnace unit will rise and help warm the floor. Insulating will trap heat in the basement.
There are several ways, but probably the easiest way would be to temporarily buck under the afflicted ceiling joist with a 2x6 temporarily, until the joist is in line with the others. Then go into the attic and cut and attach a 2x6 to the joist and vertically to the roof ridge. Remove the buck. The joist should stay in place.
Not knowing if the joist are in need of repair from rot (deterioration) or broken/damaged then replace ment of joist may be necessary. First get a replacement joist of the same or better species and treatment content and dimensions as the existing joist. Then cut the joist to the same length. You may have to cut a small angle on the bottom end of the joist to aid in working it over and between the girts and decking boards. Work the joist within a few inches of the joist to be replaced. Use a short 4x4 to drive the joist or a wood block to strike with a hammer. Take a couple of scrap 2x's and temporarily fasten to the girts and new joist to prevent movement. Then you may try a couple methods to remove the old joist. If the decking is fastened with screws then simply backout the screws. If it is nailed, then a 10 lbs. hammer can often remove most anything you need and is a great stress reliever but I recomend you use a reciprocating saw to cut the fasteners between the joist and decking. Usually the vibration of the saw and nails being cut will loosen the deck side of the fasteners and allow you to go top side and pull the old nail halves out. Once the old joist and fasteners are out you can carefully work the new joist in place. I recommend fastening the old decking to the new joist with properly coated screws or a hotdipped galvanized rink shank nail. Repeat joist replacement as necessary on other joist.
Floor joist or ceiling joist? Floor joist have a board on the end all the way along the side of the building called a rim joist. Like the cross bar on the top of a T. Ceiling joist are nailed down into the top plate of the wall and to the rafters where possible.
A joist is a beam, a supporting structure in a building. The roof joist was riddled with dry rot and had to be replaced.
it depen on the size of the joist
If a shim is required that means there is a gap somewhere. Cut a piece of wood which fill the gap. Nail it in.
No. You need to support it, cut it and use 2 x 2x8s to tie back into the two joists next to it on each end. Use double joist hangers. By code you would also have to double the joist (s) you installed the hangers on... That is not always possible.
