I am having my roof replaced and will install a radiance barrier at that time. My current roof is a 3-tab over cedar so both will be removed and plywood or OSB decking will be installed over the 1x4 nailers. Which would be more effective and cost-efficient? A TechShield-type decking or a radiance barrier paint applied to the decking/nailers after installation?

Hi Freejeff,

Before I offer an answer, I'd like to know what you're trying to accomplish w/the barrier? How was it 'sold' to you? By some Salesman, or on your own?

Can you give me a little 'bigger' picture???

Jay J,

Randiant Barriers in one form or another have become somewhat common in my area (Houston). My question pertains to the effectiveness of the TechShield laminated plywood decking where it comes in contact with the 1 x 4 nailers which will not be removed. I have since discovered that the laminated radiant barrier (TechShield)loses its effectiveness where-ever it contacts wood such as nailers, rafters, etc... so the paint-on variety will work best for me. Also, here are some links if you'd like to learn more about the subject.
