Insulation keeps your home warm in the winter and cool in the summer by providing resistance to heat flow. It works just like an ice chest does on a hot summer day. The better the ice chest, the longer your drinks stay cool. That's because the ice chest slows the heat transfer from outside to in. Insulation in your home works the same way by slowing the heat transfer from your attic into your home.
Low insulation means your home can't hold it's temperature very long resulting in your AC running all day. This will also result in temperature swings where your AC has to catch up while you are uncomfortable. Unless your home was built in the last 5 years, odds are, you don't have enough insulation.
I wish I had had it done years ago. It made a huge difference in our comfort at home. The biggest impact is the amount of energy and money we're saving!â€” Bill, recent customer
of a homeâ€™s cool air can be lost due to poor insulation.
Spray foam is the newest product on the market and in the proper application, it's the best insulator but we don't recommend it. It's extremely expensive. It's made of harsh chemicals that overtime, breakdown and leak into your home. Most spray foams are extremely flammable and the fumes produced in a fire are more deadly than the flame itself.
Fiberglass insulation is just as effective as cellulose when it comes to thermal resistance, typically has a lower fire resistance, and is naturally pest resistant. Applications can include loosely blown into attics or placed in walls as sheets. It's advantage over cellulose boils down to cost.
Cellulose insulation is made mostly from recycled newspaper and has an advantage of being an effective sound barrier as well as an insulator. Its applications range from being blown into attics, filling walls, or when mixed with a glue, sprayed on a surface. It is treated with borates and boric acid which allow it to be fire and pest resistant.
When it comes to choosing which type of insulation is right for you, it really simply depends on what type of application you're using it for and what your goals are. Generally speaking, fiberglass insulation is more cost-effective when used as attic insulation and works just as well as cellulose. Cellulose is really the best choice though when it comes to sound barrier and it can be spray applied to most surfaces.
