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.
unless you got a great deal on them, it would never make $$$ sense to use a microlam in lieu of a TJI joist or dimensional lumber. . .microlam is too costly if you have them on hand, I would call the manufacturer. . .they should be able to give you the numbers or send you a book with the span charts
No gap is intentionaly left. Your squeaking will be between the subfloor and joists.
AnswerIt is a sill (sills: the horizontal timbers of a building) which rests on the foundation, meeting the ends of the joists--(a plain old "joist" is one of the set of parallel timbers beneath the floor boards that run from one side of a building to the other).
Use a longer screw and go into the joist.
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.
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.
A joist is a beam, a supporting structure in a building. The roof joist was riddled with dry rot and had to be replaced.
