ATTIC INSULATION AND AIR SEALING
If you want to save money on your energy bills and increase the comfort of your home, start at the top. Did you know that 70% of energy loss is up, not out? By increasing the efficiency of the attic, a homeowner can begin to see a reduction in energy bills almost immediately.
Energy efficiency is about more than insulation. An efficient attic includes air sealing. According to the Department of Energy, having your home air sealed by a qualified contractor can save up to 20% on heating and cooling costs.
Air sealing prevents airflow. Proper air sealing of a home prevents airflow between a home and attic, helping heated or cooled air stay inside the home by closing the gaps that leak air. Think of air sealing like closing a window before running air conditioning – why condition the interior air if you are going to let it sneak out through a gap in your home’s envelope?
Your home may have leaks that are easy to see through a simple visual inspection. Your home also has many air leaks that can’t be easily seen. These are commonly found around areas such as light boxes, plumbing stacks, soffit drops and basement box sills. Having your home professionally air sealed and adding proper mechanical ventilation can help keep conditioned air in, pests and allergens out and ensure your home has proper air exchange.
Many times when upgrading insulation in existing homes, blown-in fiberglass is added on top of existing insulation. This adds R-value to the home and creates a fresh new blanket of protection.
Even newer homes can benefit from upgraded insulation. As building codes increase, nearly all homes need more insulation to ensure they are meeting current standards.
