Using the recommended level of insulation in your attic, walls and floor is your primary defense against heat gain in the summer and heat loss in the winter. Having the prescribed amount of insulation increases your home’s thermal performance while decreasing heating and cooling costs, improving comfort and reducing noise levels.
What most contractors and homeowners are not aware of is that there is a direct relationship between insulation and other components of the home such as: framing, plumbing, electrical and architectural design. When this relationship fails, which is extremely common, the effectiveness of the insulation is compromised. A failure rate of just 5% will reduce the effectiveness of your insulation by half. Due to such failures and other instances where insulation quantity is insufficient, the U.S. Department of Energy has estimated that 99% of all homes in America are not properly insulated.
