Insulation

[Sasquatch912]

Just got done with my metal building. Everyone said I shouldve gotten insulation but I didnt. It was going to cost 200-300 extra...but im a tight wad.


Since ive finished putting up the building i am thinking hard about insulation and OSB walls.

I was thinking about OSB the walls and roof. But debating about blow in insulation or the insulation rolls.


any opinions?

Looks like board insulation would be easiest. if you do the dense pack cellulose i would spray foam all the seams first to make it more air tight.

How does the board insulation go up? Never done this before
Sorry for the stupid question

I guess you could glue it to the metal. How deep of a space will you have between the outside metal and your inside finished wall?

Maybe 1-3" i think...i cant remember

not sure with your construction..I would say spray foam, but if $200-300 for blankets was out of your budget....be sure you are sitting down when you see the foam estimate.

The construction will make adding insulation tough, as the only structure to attach things to, is the steel framing, and it appears that the top steel is not weather tight. That needs to be addressed before you do any insulation of any kind.

"boards" are easy and less expensive, but need a nailer or stringer to attach to...your construction does not support that.

You might go back to your builder/installer and see what others with buildings like yours are doing and at what cost for what R- level of insulation.

Best of luck.

is your roof rated for insullation and board?...along with the snow load for your area?

$5220 for closed spray foam..

:-(


No snow load in my area..rarely get snow. Its South Georgia. It has snowed several inches but very very very rare.

My building wouldve came with insulation you put up before the metal was put on.

Called the metal building supplier.

They have rolls of insulation but they were supposed to be installed before the metal siding.

Looks like less than $500 i could use that but there will be no good way to install it.

The batts that go between post can be installed after, in fact I dont know anyone that installs it before? The stuff they are talking about is probably not truely insulation but a 1/4" thin styrofoam or foil/bubble product that is for preventing condensation.

Any way to install the large batts that hang between poles you take two 2x4s that are the same width as the space between poles. You screw the 2 2x4s together with the top edge of the blanket between them. On the side of the pole up between the header girts you put a small block of 2x4 on both side of each pole. Then it just involve poking the sandwiched 2x4/batt up at a slight angle and setting on the two blocks you installed. Some install one block before hand and the other as they set the batt.

Its insulation

Question.

Do you guys want me to cover up every crack on the roof? You can see all the spots.

I was using caulking but I am thinking about using Great Stuff Foam.

I thought i was suppose to leave a few holes so air would escape when i do decide to put up insulation.

What can i use as a vapor barrier?

Any opinions?

 

[2012Eli3]

can't see how deep/thick your steel structure is ? Spray foam won't need vapor barrier than use steel panels for interior liner and you can attach to same structure as exterior steel attached to. Might need to make sure your ridge vent(my guess) is correct to keep out blowing rain(a lot of light shining in). Spray foam, no vapor barrier, steel liner panel inside

For the board insulation you can cut panels to be a "tight fit" if you are careful and take your time. Also you could use Loctite PL300 which is a water based construction adhesive to help out. I don't know for sure if it affects the metal skin but I wouldn't think so.

The only issue if there is condensation behind the panels they won't seal out the moisture as the spray foam would (which is completely bonded).

Are you insulating to heat this or to air condition (or both?) All of the light-emitting orifices will have to be sealed to make either one effective.

Correct....no easy way to install it now. Penny saved.....pound foolish.
