Do I need to cover it up?

[edcantu9]

Hello all. I am insulating my garage. I just finished up the ceiling it is cathedral style. I put in baffles from soffit to ridge vent, and then the insulation with the paper facing towards the inside of the garage. The walls I did cover with OSB after insulating it. I also installed garage door foam insulation and also installed a Snirk It under the door to seal gaps.

I am looking for advice on what to use to cover up the ceiling with, or can I leave it like that for a while? I do plan on heating it, and I did install a through the wall AC already and it cools down really fast and its nice to work in. I will be installing a 5,000 watt small heater for the winter.

OSB is too heavy to be lugging up to the ceiling, I tried foam board but unless I cut it into small 2'x2' sections it will be difficult due to so many obstacles to fit around that it would take a while to fit it piece properly.

Is there something easy that will work around most obstruction to make installation easy, or like I stated I am not opposed to leaving it open if it would not cause any issues, but I know that it would help to keep it more insulated if I add something else up there.

All advice welcome!

When I finished the ceiling in the single bay side of my garage I used 7/16" OSB and rented a drywall lift. Rental was about $25. Picked it up Saturday afternoon and returned Monday morning.

depending on your humidity and how well you stapled the ceiling insulation up there, it is a matter of when it will start coming down, not if.

Thanks for the tips! I could add more information. It is a detached garage 22'x24'. Located in Iowa.

Another question to add in if I add this type of foam board up cover studs and insulation is it okay or Do I also have to add drywall to it?

That foam is pretty stiff - it would work. Just $$ compared to OSB. And FWIW, my olf 20x24 shop has exposed kraft backed insulation on the ceiling, never got around to putting anything over it. We were there 13 years, never had to re-staple or do anything to it.

I'd still do as duck mentions above. It will look great.

That said, if you're not generating sparks that could catch the ceiling on fire, rigid foam seems like it would work.

That would be my only concern as well. if you're not welding/grinding it will be fine.

How about corrugated metal siding/roofing. Light weight and it goes up easy. Color of your choice too.

Falcon67, i am surprised and glad that the insulation stayed up. i have seen them coming down. i think it really depends on how well they were stapled up.

Give this product a look - AtticFoil® is tear-proof and will not tear when you are stapling it up.

I put thick plastic up and used 1" cardboard squares to staple through. I had a couple of hard rains that were literally blowing sideways and forced water under the shingles causing leaks. The plastic held everything, including about a gallon of water.

I'd personally want the foam covered. They make spray or roll on coatings that brings foam up to required fire rating code.

You could put the same coating over your OSB walls if you're worried about it.

Many guys on the board have gone with metal coverings on the ceiling recently. Looks simple enough to install, is very fire resistant, is probably lighter than drywall and requires no finishing once hung. In your area you could find it at Menards (Pro-rib steel panels) sold at 16' lengths.

The only cons I can see are that they don't insulate sound very well and hold/transfer heat as opposed to a more neutral wood or drywall. Although, if you insulate above and seal the seams I think that wouldn't be very much of an issue.

Wow thanks for all the advice! Will definitely be able to come up with something after all these ideas!

Voi-Have any idea what the coating is?

also he said above he had a lot to go around. so I wouldn't. on a straight shot ceiling it would be great besides the price. goes up very quick with no obstructions

There are several. I would Google [foam coat fire rating] without the brackets as a start and see what's out there. They have been discussed here on GJ but I suspect it's a hard subject to search.

I HAD to use 5/8" Sheet Rock on mine because there is a living space above and that is what the code required. I did use the garage before it was finished. One thing to keep in mind if it is left open is the amount of dust and dirt that can accumulate on the insulation. Especially if doing a lot of cutting, grinding, etc.

My ceilings are over 10' high. We did two sheets by hand and it was a major pain in the ****. We then got hold of the sheet rock lift and it became quite a bit easier. That would be my choice. It's durable, easy to paint and easy to clean and cheap. I would go with 1/2" if there is no living space above thought to make it even easier to install.

Good luck.

I used 1" foil faced styro with foil tape on the seams (detached garage). Looks like a chrome ceiling. Went up quick and easy. Blew cellulose on top of that.
