Insulation is the best investment that you can make for your home. Even if you go for more expensive materials and pay a hefty price up front, you’re almost sure to recoup that money with lower utility bills over time. If you don’t have the money to upgrade the insulation in your entire home, consider upgrading one area at a time. Learn more about the types of insulation available, the areas in your home to insulate, and cost considerations involved in home insulation.
Blown-in insulation has been used for many decades in homes all over the United States. It is often made from recycled newspaper in the form of cellulose. It insulates very well and has a higher than average R-value, depending on the depth that is blown.
Spray foam insulation
Spray foam insulation seals leaks and gaps inside existing walls and is the perfect solution for those who are looking for a relatively inexpensive way to fix a larger problem, while increasing the home’s R-value.
Fiberglass batts are among the most inexpensive ways to insulate your home, especially when the walls are already open, like in an attic area. The important part about installing fiberglass batts is to pay close attention to how they are installed. One loose corner or tear reduces the R-value accrued from the installation.
Reflective or radiant barrier
Usually installed in attics to reduce summer heat and insulate against winter cold, radiant barriers are perfect for reducing heating and cooling bills, while increasing your home’s R-value. Reflective barriers, though different in design, function similarly.
Since most homeowners are looking to insulate previously built structures that have drywall, blown-in insulation typically works best in the interior. A hole is cut, insulation is blown in, and the hole is sealed, leaving the room warmer and more efficient at about $1.00 per square foot.
Roofs need to be sealed prior to the installation of insulation, which means seeking out and filling gaps, closing vents, etc. This is due to the fact that, over time, water degrades insulation, rendering it completely useless. An insulated and sealed roof leads to a warmer attic in the winter and a cooler attic in the summer. Look to spend approximately $1500 to pay for a professional job, or a bit more for radiant or reflective barriers.
Insulating garage doors
If you have an attached garage, or simply want to keep your garage cooler in the hot summer months, insulating the door with foam is simple and only takes a few hours to complete. Depending on whether you opt for batts, foam boards, or reflective insulation, you will likely pay about $200 for a 9’ door.
Insulating the attic
Keeping your attic warm in the winter and cool in the summer especially is costly. Insulation is the wisest choice to ensure that your attic temperature is cool and manageable, especially in during the hot Phoenix summer. Though not considered to be a DIY job due to the dusty and cramped environment, insulating your attic brings hefty benefits in terms of savings and increasing your home’s R-value. The good news is that attic insulation can be installed correctly by a professional for a relatively low price. Estimates vary depending on the insulation type that you choose. For the most part, however, look at paying around $1300 to $2000 total.
