How Attic Insulation Works
Attic insulation is one of the most cost-effective home upgrades you can make to reduce energy waste and save money. It keeps conditioned air from escaping your home during the summer and winter, helping you avoid overworking your HVAC system. Go here https://newgenerationsprayfoam.com
ENERGY STAR recommends working with a Building Performance Institute (BPI)-certified contractor for an attic sealing and insulation project. This professional will test the effectiveness of your existing attic insulation and help you choose the right R-value for your region and home. The BPI-certified contractor will also seal air leaks to prevent conditioned air from leaking into your attic, reducing the amount of heat that is lost in your home and driving up your cooling costs.
Proper Insulation Saves Energy and Improves Comfort
The most common and affordable type of attic insulation is fiberglass batt insulation. This material consists of tiny slivers of glass fibers that were originally sand and recycled materials. It is available in a variety of thicknesses, each designed for different climates and homes.
A more expensive option is spray foam insulation, which can be applied to the attic floor or sprayed onto attic walls and roof rafters to fill cracks and gaps. This type of insulation provides high R-values and acts as both an insulator and an air barrier, helping to keep your home cooler in the summer. However, it is a messy application process and should be left to the professionals.
Other types of attic insulation, such as radiant barriers, are designed to reflect the sun’s heat rather than absorbing it. These materials are effective in hot climates where they help keep your house cool in the summer.
