Insulation plays a significant part in controlling the air infiltration into your home. Air infiltration is the flow of air in and out of your home through gaps, cracks, and poorly insulated areas. Sealing leakages, increasing or improving insulation and duct sealing can all help to reduce this unwanted air exchange. According to Energy Star, the benefits of air sealing your home’s building envelope include:

• Increased Indoor-Air Quality: IAQ increases because less outdoor air pollutants, such as dust and pollen, are able to enter the home.
• Lower Utility Bills: Air infiltration accounts for 25-40% of energy used to heat and cool your home. A tightly sealed home will experience lower utility bills because there will be less conditioned air escaping from it.
• Increased Comfort: These measures result in a more consistent temperature throughout the house, which means you can stop taking your sweater on and off again.
• Staying Ahead of the Game: In the future, building codes may increase insulation requirements. By taking steps to properly seal and insulate your home now you will be ahead of the game.
