Gentlemen, first thanks very much for maintaining the forum. I’m sure it’s hard work and tries your patience at times, but it’s unbelievably helpful for the do-it-yourselfer. I just retired from the military after 30 years and bought my final resting place in Texas. Only problem is it doesn’t have a garage...so I’m building one (3-car, detached, upstairs bonus/storage room). I’m hiring contractors where necessary, but trying to do most of it myself to save money.

We finished the foundation and slab about 10 days ago and started framing today. I need your help with an issue that came up today. I just bought the OSB to sheet the new garage -- 100 sheets of regular OSB for the walls and roof, and another 50 sheets of tongue & groove OSB for the upstairs bonus/storage room floor. They had a good deal on something called "radiant barrier" OSB (foil on one side). They said it would help a little with the heat here in Texas. I bought it since it was only $1.50 more per sheet. I intended to buy it only for the roof. However, I "accidentally" ordered all 100 sheets (walls & roof) in "radiant barrier." I asked if they would exchange it, but they said I'd have to pay a 15% restocking fee and additional delivery charge.

My question is this. Can I use the "radiant barrier" OSB to sheet the walls of the garage? Will there be any electrical issues related to the foil (metal)? Any other problems using it for the walls...other than being blinded when the sun hits it? Again, thanks for your help. Tom

heck no , itll add to the "k" value of the walls. reflective though works best when there is airspace in front of it i.e. no insulation smashed up to it, or contact with the ground . it cant hurt...

Thanks for the reply MD. My main concern was the foil on the OSB and the possibility that an electric wire running through the studs could be shorted out on the foil. I understand you don't think that'll be a problem?

Also, you gave me some useful info. I had intended to insulate the walls and ceiling with the pink corning rolled insulation in addition to the radiant barrier OSB. But I understand you to say it works best with just airspace and NO additional insulation, just airspace.
