Attic Insulation Installation Guide
Homeowners who install insulation properly can reduce energy waste, feel more comfortable and save money on heating and cooling costs. However, attic insulation is a fairly labor-intensive and technical project that requires some level of DIY expertise. Here’s a guide to making the process easier and avoiding common errors.
Before starting an attic spray foam insulation project, clear the space of storage items and other clutter. This can help you see what you’re doing as you work. During the installation process, you don’t want to compress or bunch the insulation, as this will significantly reduce its insulative capacity.
Best Insulation Options for Different Climates
Once you’ve cleared the attic, it’s time to begin insulating. First, make sure to wear personal protective equipment (PPE). Read the bag instructions and determine how much blown-in insulation you’ll need for your attic. Generally, it’s best to err on the side of buying too much insulation and returning what you don’t use.
When the attic is clean and ready for insulation, a worker can remove the plank floor boards in sections to blow loose-fill insulation into the spaces between the attic joists. When working in an attic with a blown-in insulation system, it’s important to be careful not to get insulation near electrical wires. Homes built before 1950 often have wiring that uses porcelain cylinders or tubes inserted in holes in the wood attic floor joists, called knob and tube wiring. This type of wiring is a fire hazard and should be replaced before installing insulation.
