When it comes to insulating your attic, there are a few factors to consider. The R-rated insulation your attic should maintain depends on the climate you live in. For warm climates, an R30 is recommended, while cold climates require an R49 and moderate climates should settle close to the middle. There are several types of insulation available on the market today, each with its own benefits and drawbacks.
Let's take a look at some of the most popular options.Fiberglass InsulationFiberglass insulation is one of the most popular types of insulation on the market today. It is made of glass fibers spun on a rug and then packed between two sheets of paper or aluminum foil. Fiberglass insulation is available in rolls, blocks, and loose shapes, making it easy to find the right type for your needs. One of its main benefits is that it is very effective at trapping heat, helping to keep the house warm in winter and cool in summer.
Fiberglass insulation doesn't encourage mold growth, making it a safe option for any home. Although more expensive than other types of insulation, fiberglass insulation is a good investment that will result in lower energy bills and a more comfortable home.
Aerosol Foam Insulation
Aerosol foam insulation has several advantages over other types of insulation, including its ability to provide an airtight seal that helps prevent drafts and pests from entering. It's also fire resistant and doesn't settle over time like fiberglass insulation. If you're looking for an energy efficient way to insulate your home, spray foam insulation is worth considering.Cellulose Insulation
If you check with the Cellulose Insulation Manufacturers Association, they will assure you that cellulose is definitely your best choice for insulation.Loose fill insulation is ideal for installation in attics with very little free space and with multiple obstructions, such as ventilation grilles and cross beams. However, when properly installed, cellulose insulation can provide an effective barrier to heat loss and help reduce energy costs. When properly installed, both types of insulation fill all the nooks and crannies of a space and form a perfect air barrier.Blown InsulationBlown insulation is usually made of fiberglass or cellulose and can be added to both attics and walls. Loose-filled fiberglass seems to dominate attic insulation in newly built homes and has an R-value of approximately 2.5 per inch.
Cellulose insulation is made from recycled paper products and is one of the most effective forms of insulation. If you live in a warm climate, you'll want to focus on attic insulation with a higher R-value to help keep your home cool in summer.Massachusetts has all four seasons of the year, so make sure you have adequate attic insulation that can withstand extreme cold and heat. The most effective way to insulate an attic does not always coincide with the most cost-effective way.
