Installing the right insulation for your home and climate can result in reduced utility bills and perhaps, most importantly, better comfort. However, how do you know what the right insulation is for your home? There are many different types of insulation commonly used in residential homes, and you may be wondering which one is best if your home is in Virginia? In this article, we are going to discuss why choosing the right insulation is important, how to determine the quality of insulation, and which material is best for your home in Virginia.
Why is it Important to Insulate Your Home?
This may or may not come as a surprise, but heating and cooling accounts for almost 50% of energy use in an average United States home. Research from the Department of Energy revealed that heating and cooling makes up a significant 48% of total energy use. However, while utility bills continue to rise and household budgets face increasing strain, there are basic things you can do around your home to not only beat the winter chill but also save money.
Installing the right insulation for your home can significantly help reduce your utility bills and keep you comfortable throughout all four seasons. Insulation essentially works by stopping the transfer of heat. During the cooler months, insulation inhibits the cold air outside from coming inside. When the weather heats up, insulation helps trap cool, conditioned air inside your home, while stopping the heat from outdoors penetrating indoors. Insulation is one of the most important features of any energy efficient home.
Determining the Quality of Insulation
The quality of the insulation you need will depend on where you live. The climate of Virginia is relatively mild, which means if you are a resident there, your needs for heating and cooling will be moderate. However, you need to ensure the insulation you choose follows the minimum R-Value guidelines.
While improving the insulation around your home can offer significant returns on investment and improved comfort, it is important to know all your options and the potential benefits and disadvantages of each.
The Best Insulation for Homes in Virginia
There are four types of insulation commonly installed in homes in Virginia: fiberglass insulation, spray foam insulation, cellulose insulation and mineral wool insulation. Each insulation material has various pros and cons in terms of price, effectiveness, sound protection, how easy it is to install and some other factors. As we mentioned before, it is important you adhere to the Energy Star Insulation Recommendations for Virginia, which are:
- Uninsulated attic: add R38 to R60
- Existing 3-4 inches of insulation: R38
- Floor: R25 to R30
- Uninsulated wood framed Wall: R5 insulated wall sheathing
- Insulated wood frame Wall: R5 insulated sheathing
