What’s in my attic, anyway?
If you’re like most people, you know that you probably have insulation in your home, but what is insulation anyway? What does it do and what is it made of?
- Insulation is a thermal barrier. Insulation helps maintain the internal temperature of your home – in winter and summer, by keeping the conditioned air in the home. Your insulation is rated by an R-Value which stands for the resistance to heat flow. Basically, the higher the R-Value the greater the resistance to letting that conditioned air escape your home. (IMPORTANT NOTE: Air sealing makes a difference by also stopping air flow. This is why adding insulation is just part of the solution – you need the combination of air sealing AND insulation to realize the greatest benefit)
- Insulation is an energy saver. Energy bills rise and fall based, in part, on how often your furnace or central air systems run. These systems run more when the internal temperature of a home isn’t consistent. By having adequate insulation, your home’s internal temperature is more easily maintained resulting in saving energy and money.
- Insulation is fiberglass, cellulose and spray foam. Fiberglass, cellulose and spray foam are the three most common types of insulation. Each saves energy, but each has specific benefits to offer. The type of insulation recommended for your home depends on which area of the home you are insulating as well as your budget. We typically recommend that fiberglass blown insulation be used in your open attic, dense-packed cellulose be used for “drill and fill” in your existing sidewalls, and spray foam for your basement boxsill area.
