Both of those the Florida Photo voltaic Electricity Center and Texas A&M College assessments reveals for homeowners in sunbelt states are better off to put in radiant barrier over incorporating far more mineral insulation. The two experiences condition that R-19 and radiant barrier is definitely the equivelent of R-30 or much better. The US Dept of Electrical power efficiency and Renewable Power states the following."
