Vapor Barriers Basics
Experts recommend at least on square foot of inlet vent and one square foot of outlet vent for each 150 square feet of attic floor area. However, this can be reduced by one-half if you install a vapor barrier beneath the attic insulation.

Insulation Facts
Insulation value is commonly referred to as resistance-value or R-value. R-value is the measure of a material's ability to resist heat flow. The higher the R-value, the more effective the insulation is in reducing heat flow. Insulation should be purchased on the basis of its R-value, not thickness or weight. One brand or type of insulation may be thicker or thinner than another. But if both have the same R-value, they will insulate equally.
