Tips for working with Insulation Contractors
Ask the contractor what “R-value” of insulation they will install. “R” means resistance to heat flow. The higher the R-value, the greater the insulation power. When insulation is installed, your contractor should provide you with a written statement of the R-value as required in the Federal Trade Commission (FTC) insulation regulations.
