Can this be installed in the attic onto the underside of the roof?

7/16 in. x 4 ft. x 8 ft. OSB TechShield Radiant Barrier
Asked by: Anthony
why would you want all the extra weight ? just install the radiant barrior alone to the underside of the trusses. it comes in a roll just like tar paper.

Question 1: Why is a space of 1/8 in required between sheets when installed? Question 2: What are the "clips" referred in the installation instructions?
Asked by: Willy
I believe it's to allow for expansion as wood will continually expand and contract with differences in weather.

Is this 1/2 inch

Asked by: Linda
It is 7/16 inch thick, which is 1/16 less than a full half inch. For practical purposes, it should be used as if it were 1/2 inch sheathing. The reasons why the industry does it this way are complicated, and important to manufacturers and engineers, but not interesting to the rest of us. Happy Trails

7/16 in. x 48 in. x 8 ft. OSB TechShield Radiant Barrier is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Tech shield really does seem to work House uses plain 7/16" OSB decking with a standard gray 3 tab shingle, one layer, tar paper underlayment. Underside of OSB with good venting runs 120~130F in full sun, air temps in the 90s. Used Tech Shield on new detached garage with same color and type of shingle, underlayment, similar venting, exterior air temps low/mid 90s. Underside temps run mid-high 90s with only the ridge beam running 100+. New house next door used Tech shield - laser temp survey during the 2011 summer build also showed 20~30F reduced underside temps.

Rated 5 out of 5 by from You will never deck a roof with anything else again!!! Techshield radiant barrier on this OSB is a no brainer for anyone re-doing a roof or siding, or building a new home or garage. When compared to conventional OSB there must be at least 25 degrees difference between the old OSB and the Techshield. If you are not cooling your garage (I live in southcentral Texas) you will definitely feel a difference with this product. I keeps the heat out of your attic in the summer and helps hold it in in the winter.

Rated 5 out of 5 by from This stuff works I was reluctant to try this product for my roof and gables. I figured it was nothing more than Just building industry hype, but I gave it a shot on a small shed project. And what do you know, this stuff really really works. The shed is 100x cooler, (exaggeration) even in winter with this hot Deep south sun. on these "mild" days of 75 degrees or more. I was surprised. The panel is fairly cool to the touch while the rest of my OSB sheathing is warm to the touch under this sun. I am building my house and this will be used all over the roof.
