Insulating a shop ceiling
 

Hi everyone
I have a shop with OSB sheeting looks like (wood chips glued together) on the ceiling with pole barn tin coving it.
It needs insulating and not shure on what to use blow in,foam,unfaced,faced insulation.
I heat it in winter and ac in the summer if that helps
thanks brian

Is your roof vented. If it is, I would just use blow in to the correct R-value for your area. Most likely it will be R-45. The blow in stuff is as easy as it gets. You could do batt insulation, but you'd have to move around the area and that might not be worth it.

yes it is vented would I have to put plastic down first then blow it in thanks for the info

Right good catch - the plastic is necessary as a vapor barrier to keep the insulation dry.

could I use faced insulation and not use plastic as a barrier thanks to all for the info

Yes, barrier goes to the warm side (facing down).
