OSB w/radiant barrier question

[gnab2]

Ok. Here we go.... Who has used the OSB with Radiant Barrier on the inside of their shop? I am thinking of using it on the ceiling to reflect light and to help with the Texas heat in a metal building. I have the roof insulated however it still gets toasty. I was looking at doing the RB OSB so that it may help a bit more.

What are your thoughts?

I use it on every roof surface and western facing walls. It works great.

I use it on all roofs I do since 1995 when it was first available to me. It does make a difference in heat transfer.

I used it - the shop underdeck temp is about 20F cooler than the house which has plain OSB. IMHO, it would need to be on top to work well - like a roof deck, not under the insulation.

Falcon67 is right, it is a reflective barrier, so it has to be on the roof deck.

I have it in my house garage and the rest of the house is spray foamed. I guess I will find the same radiant barrier stuff that is used roof and glue it to the metal and then use something to like OSB and paint it bright white in high gloss to reflect light.

You can buy radiant barrier in big rolls. That might work for you.

I may use the radiant roll barrier then put the backed 4" insulation. I hope it will keep things cool here in Texas. Hell will freeze over but Texas will not.....
