Improve Your Home's Energy Efficiency With Blown-In Wall Insulation
People often focus on attic insulation when they want to improve the energy efficiency of their homes. However, wall insulation is important too. If you have an existing home, you may not know what kind of wall insulation you have or what condition it is in. Fiberglass batt insulation is a popular choice for walls, but if you want to add more batt insulation, you'll have to rip out the drywall.
