NO NO NO!!!! This product WILL NOT WORK with 16" on center TJI/Engineered/I-beam floor joists!!! They are only 15 1/2" inches long and you will need rods about 16 1/2" long - the space between the OSB portion of TJI beams is 15 1/2 +/- - buy the 24" type and cut each one. It's a pain but doable. These are made for dimensional lumber ONLY.
Yes
Space them about every 3-4 feet. This may vary if there are pipes, duct lines, ect. Good luck
Im no Mason but I have always called the wall ties, or just Ties.
The spacing would depend upon the weight of the type of insulation, as well as how snugly it fits into position. The ties are cheap enough, so I wouldn't go more than 2 feet apart on hung insulation lengths. Especially if it is a "loose" fit.
yes, you can as long as stud spacing is 16". But put more (about 50% more) ties than what is specified.
