Air leakage is the number one cause for energy inefficiency and high utility bills. Air infiltration can account for up to 40% of heat loss from a building. It is also the primary cause of moisture buildup and subsequent damage to your home's structure. Good insulation has been proven to be a fundamental solution to the long-term health of your home, as well as your pocketbook. Most residential buildings are insulated with fiberglass or cellulose due to their low cost. However, there is more to insulation than R values. Air has the ability to move through fibrous types of insulation. This air movement greatly reduces the effectiveness of the insulation. Fibrous insulations are vulnerable to moisture, which reduces their performance and increases the possibility of mold growth.
All buildings must be insulated to meet minimum building codes. Over the years, as energy supplies have been reduced, building codes have changed to require more insulation. But, more insulation does not directly relate to a more energy-efficient building. Design, quality of workmanship, additional caulking and high quality insulations are the factors that will make a building truly energy efficient. Based on the current cost of energy, building an energy-efficient home will pay for itself within 6 to 7 years. As the cost of energy continues to rise, this payback period will become shorter and shorter. As the world's supply of oil declines, demand will increase and energy rates will continue to rise.
A well-insulated house will:
• Lower Monthly Power Bills
• Improve Indoor Air Quality
• Provide Greater Comfort
• Create A Higher Resale Value
• Be A Quieter Home
• Help Prevent Moisture Problems
• Reduce Air Pollution From Power Generation
