Attic insulation is essential for improving the energy efficiency of your home. Its importance often gets overlooked in comparison to other home improvements, but adding or upgrading insulation in your attic can significantly reduce your heating and cooling bills. It also pays off in the long run, with returns on your investment that can range from 10 to 40%, depending on the type of insulation you use.
So, how does attic insulation work? By trapping air inside of your attic, insulation slows down the process of air escaping from your home. By keeping the air inside, insulation helps to regulate the temperature in your home, keeping it comfortably warm in the winter and pleasantly cool in the summer. The slow but steady process of air escaping from your home can cause a never-ending battle between you and your energy bills, but proper attic insulation is a great way to reduce that battle.
As you can imagine, the type of attic insulation you choose makes a huge difference. Different insulation materials offer different benefits. Fiberglass, for instance, is one of the most common and cost-effective choices. It’s made up of tiny fibers of glass and nylon that create a thick layer of insulation that reduces sound transmission, in addition to providing protection from heat and cold. As with most insulation types, fiberglass breaks down over time, so it’s important to replenish it every 15 to 20 years.
Cellulose insulation is another popular option. It’s made out of recycled newspaper, paperboard, cardboard, and other fibers that have been treated with fire retardants, making it one of the most eco-friendly solutions. Cellulose is particularly effective at preventing heat from escaping during the winter, and since it doesn’t contain any harmful chemicals, it’s great for those who suffer from allergies.
But perhaps the most effective insulation you can use in your attic is spray foam. Several different types of foam are used, each designed to fill in almost any nook and cranny, creating a tight seal that’s almost unmatched. Spray foam is most effective at regulating temperature, and it’s so good at preventing air leakage that it can even help decrease the energy used to run your home cooling system.
No matter which type of insulation you choose, proper installation is key. It’s important to have an expert come in and assess your attic to determine the best type and amount of insulation needed to make the most impact. Leaving your attic without proper insulation could cost you hundreds of extra dollars in energy costs each year, so it’s best to make sure everything is done correctly.
