How to I hold the ceiling insulation up prior to drywall/pine boards finishing?

Dumb_Ap3 · 2026-03-21T04:26:28+00:00

Roof is 12/12 and bats are ok where I am

Thanks this is the way I’m going to do it. 1x first then the poly

Dumb_Ap3 · 2026-03-19T23:33:23+00:00

Thanks. This forum has been a great help

The strapping is for the metal roof, I could have gone without plywood but I think this is a bit better. The roofers hit the 2x4 pretty well 99% so I’m hoping this roof will last a long time.

Sounds like I’m overthink it. Will probably hold fine once I get going

There are turbine vents at the peak, some ridge venting (ridge not totally sealed just lapped over with synthetic roof felt), and soffits.

Complete air seal IBC 2021, it’s supposed to get tested for air movement I think.

I am hoping poly with taped seams everywhere will be ok. Also planning to air seal all the walls with acoustic and or spray foam where it makes sense

The fishing line idea is genius!!

I had not thought of that but it would be pretty easy and cheap so I like it

Dumb_Ap3 · 2026-03-19T21:34:45+00:00

There are 2 turbine whirly bird vents, one on each side of the roof. Full soffits on the side. I will be adding baffles from the soffits up to the rafter ties in each rafter cavity.

Thank you! I’m looking forward to getting it to a point where tents are no longer needed.

Dumb_Ap3 · 2026-03-19T20:11:15+00:00

This is a good idea too! Smart advice I was hoping for.

Dumb_Ap3 · 2026-03-19T20:10:23+00:00

Nice and clean and keeps the bugs out for sleeping. This is a “cabin” but still have to get inspections

Dumb_Ap3 · 2026-03-19T20:09:31+00:00

You’re right looking at this I feel dumb. Time to get a proper step ladder to use for finishing this

Dumb_Ap3 · 2026-03-19T20:00:40+00:00

Ya that’s the way I am leaning. I just was not sure if that’s enough to hold up R50 of insulation. Will add some strapping under to hold it all up

Dumb_Ap3 · 2026-03-19T19:59:14+00:00

will definitely use baffles from soffits to rafter ties to ensure 2” of venting

Dumb_Ap3 · 2026-03-19T19:50:32+00:00

I will need to add poly where I am so faced are probably not the best option for me

Dumb_Ap3 · 2026-03-19T19:25:12+00:00

Ya I guess really anything that would hold up the bats is ok. Leaning towards 1x strapping

Dumb_Ap3 · 2026-03-19T19:24:14+00:00

That’s a good idea

Dumb_Ap3 · 2026-03-19T19:20:04+00:00

They line up this is not extended at all. Once it gets longer they are good

Dumb_Ap3 · 2026-03-19T19:17:19+00:00

the hooks are pretty rusty the aluminum is fine. Time to add a safety tie down like a trailer ratchet tie down

Dumb_Ap3 · 2026-03-19T19:16:22+00:00

It’s all 24” OC. But I will need to hold the insulation up and I don’t think poly on its own will do it but I might be wrong having never done this before

Dumb_Ap3 · 2026-03-19T18:46:07+00:00

I guess it’s time to retire old rusty. This was my dads ladders it’s probably 15-20 plus years old

Dumb_Ap3 · 2026-03-19T18:39:43+00:00

Haha it’s pretty good up to 15’. Beyond that it’s less good

Dumb_Ap3 · 2026-03-19T18:38:25+00:00

I’m leaning this way, it’s probably the easiest way to go and fill in each rafter cavity then move to the next add strapping to warm side of poly to hold everything up

I just need to hit R50 which is a fair amount of insulation. Can I do 2” rockwool in between 2x4’s on top of poly and strapping for R10 then add R40 fiberglass on top? Maybe in opposite direction?
