Insulation and Radiant Barrier

[cyndyt99]

is it beneficial to have both insulation and radiant barrier done?

[inspector57]

It depends on the situation, but yes there should be both insulation and a radiant barrier if a radiant barrier is used at all.

The correct answer is to run the numbers for pay-back to make an informed decision.

Depending upon the attic structure and access installing radiant barrier under the roof decking (between the rafters) is very easy/simple.

I did my attic (~2000 s.f. home) in a single-story home about a year ago.

I used Polar Ply ( http://www.polar-ply.com/ ) and spent only about $300 for the product.

BTW - I see you are in Katy and you can get the product from the regional Polar-Ply offices/warehouse in Spring near Beltway 8 and Hwy 290.
