Ceiling insulation might not be the most glamorous topic, but it’s one of the best home improvements for indoor comfort and energy efficiency. If you live in the Greater Chicago Area, you know the winters are frigid, and the summers are hot and humid. Ceiling insulation curbs the effects of both. Find out how, plus tips for choosing the best type of ceiling insulation for your home. How Does Insulation Work? Home insulation acts as a powerful thermal barrier, no matter where it’s installed. Its job is to keep the indoor climate steady, regardless of the weather. Without proper insulation, heat flows freely between your living space and the outside, making your home hotter in the summer and chillier in the winter. Insulation traps heat where you want it, reducing the strain on your HVAC system. Ceiling insulation is particularly crucial because heat rises. Without it, the heat you pay for in the winter escapes into the attic, which doesn’t do you any good. Then, in the summer, attic heat seeps through the ceiling and makes the upper floor of your home unbearably hot. Add a thermal barrier to the ceiling, and these issues disappear. Insulation is also important between floors to reduce sound transfer. You might install it above the home theater in the basement so you can crank up the bass without bothering your family. Ceiling insulation also reduces noise transfer between units in multifamily housing.
