hanging insulation in ceiling

[Hit-By-Thunder]

sitting back, trying to figure out how to insulate the ceiling in the garage.

What I am thinking of doing is laying the batts up while on a ladder. use the red tuck tape to hold the batts in place until I can cover the ceiling with vapor barrier. This way all the batts stay up on the ceiling and don't fall down with the weight of them, if they are just sitting between the bottom cords of the truss.

So how do you guys insulate and then install vapor barrier?

That's basically the way I did it and it worked well.

Edit - I stapled the duct tape in place as it wouldn't stick on its own.

They make 13ga galv. wires for holding the insulation in place. It is a little longer than the space between the joists and you spring it into place about 16" o.c.
Then visqueen with adhesive and staples.
Then drywall whenever you like.

Don't forget to use unfaced batts or slit the kraft paper facing if you don't, otherwise you'll have 2 vapor barriers.

My trusses are 24" apart, so I bought 24x48 insulation batts. Since I was sticking a 24" piece in a 23-ish opening, they just stuck in place and I stapled the vapor barrier up as I went along. The batts stayed in place with no problems.

I did the same thing. Put up the batts as I put up the vapour barrier. No problems.

hey thanks for the replies guys!!!!

I never thought of the wire idea, thank you.

No the insulation does not have the paper. The batts are 15 X 47 R28 (8 1/2 thick)

the electrical rough-in passed yesterday so onto the next step. brrrrrrrr -21c right now. I need to get that insulation up

Start by hanging your vapour barrier. Staple one edge along the wall, then bring it up and staple it to the first truss, effectively closing off one row and making a "trough" where you want the insulation batts. Pull it nice and tight as you staple it up. Now, lay the batts in the "trough". When finished the row, staple the VB to the next truss, rinse and repeat. The last row at the far end will be a bit tight, but usually the row by the wall holds the batt tighter anyway, so you can probably just work your way along, putting up a batt, stapling up the VB, moving back, repeating until done. Much easier and faster than screwing around with tack strips and other **** to try and hold the batts in place.

All insulated in 2 days, last Saturday and Sunday. Sure is quiet in there The R28 batts actually stayed up between the 16" center trusses. I was able to do 2 complete rows (23'X8') then put up the VB. Pulled nice and tight so no winkles in it.

Thanks guys

so if the kraft paper is VB, then why install a separate VB....Why not just use paper faced insulation and face it down? Obviously you dont want a VB surrounding the insulation.

No comment on the thread, but is that just a poster, or a live-in? Beautiful.

I don't think you can get kraft paper backed insulation in Canada. It is also not considered a vapor barrier in this climate. Earlier this week it was -30 celcius.

I put mine up with a few 1x2s for support and staples down the edges, planning to go back over it with something. 12 years, no something yet...

The kraft paper is a vapor retarder,not a barrier.
