Converting a shed into a home office doesn’t take a lot. The space is small so foam board insulation is a great option. Fill all gaps with spray foam and you’re good to go. You could also go with a she shed or man cave.

Does it matter what’s side you place outward? R-TECH or silver?

Should have installed them the other way or left an air gap so the radiant barrier could work.

Thanks for the feedback. Per manufacturer guidelines, the metallic side “may” provide additional “R” value if facing a dead air space. I chose to put the metallic side facing the exterior wall to assist as a moisture barrier. I’m sure an argument could be made either way. With foil tape and spray foam in all gaps, this will be a solid insulator.

Isn’t foam board very combustible? I read that you have to paint it with a 15 minute thermal barrier.

Most insulation is not flame resistant unless specified.

I bought myself a small 4 x 8 wooden shed recently. It’s a lean to Shed. I’m going to use the same brand, Rtech and it’ll have an r value of R.5.78. Right now during the daytime in the summertime it gets super hot inside my shed. I hope that adding all these on the walls and the ceiling will make a dramatic difference during the middle of the day. Also, what about winter time? I live in Northern California so it gets kind of chilly but it doesn’t ever get freezing cold. I assume in the winter time, it will be comfortable inside the shed?

Thanks for reaching out. It is tough to say how effective the insulation will be on its own. I doubt it will help much without a heater or a/c unit. Insulation is meant to help maintain a controlled temperature rather than regulate it. Also, sheds are not usually “air tight”. If I were to convert a shed to be a temperature controlled space, I would insulate, spray foam all gaps, and install an exterior door.

So i'm planning on doing this in my ceiling (no attic) in my office, and I was going to do about a 1 inch air gap, then 1 inch foam board with the shiny side facing up towards the roof, and follow that with R13 rolled insulation then drywall. Any issues with that? I'm just a DIY guy.

Sounds like a pretty solid plan.

@brandonnguyen1486 12 дней назад

Can you break this down for me? Did you use the foam board instead of the pink for mold reason being outside, or simply because foam board works better than the pink? Also can you please reference this to a house application with sheet rock

@projecthammer8134 6 дней назад

I use foam board insulation for sheds due to ease of installation and reduced costs compared to standard batt insulation or “pink” insulation. For a home application, this is not sufficient. For small accessory buildings, it works great.

@@projecthammer8134 wanting an affordable shed option for a home office. what if I were to use this and put up the drywall and use a space heater or a window unit. Would it do anything when it comes to temp control or will I freeze to death in Michigan winters?

@projecthammer8134 3 дня назад

For Michigan winters, go with a 1.5” or 2” foam board then you should be good in a small space. Having said that, 2” foam board isn’t much of a cost difference than fiberglass insulation. If you’re looking to maximize your insulation rating for the money, I’d stick with fiberglass if it is compared to the thickest foam board.
