Roofing & Energy Contractor

Home insulation has several functions, and proper insulation is vital to energy efficiency.

If you have noticed your utility bills climbing but your energy consumption has remained steady, you are losing heat or AC somewhere in your home. Adding insulation to your home as it ages has several benefits, including helping you keep your home at a desired temperature.

For a typical house, walls allow 30-40% of heat loss, while the roof allows 25%. Windows, doors, and floors all allow heat loss, too. Filling the gaps and adding layers will help keep your Dallas area home comfortable throughout the summer and winter. Adding insulation also provides an additional sound barrier.

How Does Insulation Work?

According to the US Department of Energy, “most common insulation materials work by slowing conductive heat flow and—to a lesser extent—convective heat flow.” Air is a lousy conductor of heat, so the small pockets of air that are trapped within the insulation lessen the amount of heat that can pass between the inside and outside of your home, consequently keeping it warmer in the winter and cooler in the summer.

There are the primary four types of residential home insulation.

  • Reflective or radiant barrier: installed in attics to reduce summer heat.
  • Blown-in insulation: made from a paper-like material (white cellulose)
  • Fiberglass batts: one of the least expensive insulators and easy to install, but itchy
  • Spray foam or foam encapsulation: seals any gaps or leaks in existing walls and reasonably priced – open cell foam is most commonly used in homes.

Be a Smart Homeowner—Considering Adding Insulation

Adding insulation to your home will mean long-term energy savings. The costs will pay for themselves over time by saving on your energy bills and possibly allowing your HVAC system to have a longer life.
