About Upgrade Old Attic Insulation
Upgrading insulation can make your home more energy efficient, reducing energy costs and the environmental impact of heating and cooling your house. It can also reduce the risk of mold growth inside your home by blocking air leaks that allow moisture to enter the walls and ceilings.
There are several signs that you may need to add or replace attic insulation. The most common are drafty areas in the living spaces and high energy bills that are disproportionate to your heating and cooling use. Degraded or missing attic insulation can also cause the formation of ice dams, which prevent water from draining off the roof when snow and ice melt.
Insulation can be added in the form of fiberglass batts, which are typically a combination of cellulose and fiberglass and can be purchased at any hardware store. However, many homeowners choose to install spray foam insulation, which is more expensive but creates a more effective air seal that can help keep your home healthier by preventing pollutants and allergens from circulating in your living spaces.
Before you decide to hire a contractor, check their references and qualifications carefully. Look for someone who is licensed and insured in your state. Some states offer rebates and tax incentives for homeowners making energy-efficient upgrades, which can help offset the initial cost of installing new insulation.
Depending on the condition of your attic and its accessibility, it may be necessary to remove some or all of the existing attic insulation before installing spray foam. This can be a tricky job, as fiberglass can contain tiny glass particles that can embed in your skin, lungs, and eyes.
