Best Practices for Attic Insulation

Best Practices for Attic Insulation
When it comes to attic insulation energy bills and keeping your home warmer in winter and cooler in summer, proper insulation is key. The good news is that attic insulation is relatively inexpensive and easy to install, even for DIYers. However, the type and installation technique can make a big difference in its effectiveness. This article outlines several best practices for attic insulation that can significantly improve energy efficiency and comfort.

1. Clear the attic of storage items and clutter.
A clean attic is essential to ensuring adequate attic insulation. During this time, it’s also a great opportunity to repair damaged or rotting attic components such as attic hatches and pull-down stairs. Additionally, a clear attic space allows you to properly examine the area and seal leaks that compromise insulation.

2. Choose a material that fits your attic and home.

There are many different types of insulation available for your attic, including batts, cellulose and foam boards. Each has its own pros and cons, but each provides excellent energy efficiency and is easily installed in an attic. For example, blown-in cellulose insulation is highly effective and is especially helpful in tight attic spaces. However, if not installed properly, cellulose can become damp and susceptible to mold and moisture damage. In this case, a vapor barrier may be required to prevent a buildup of moisture that can impact the quality and longevity of your attic insulation.

It’s important to note that standard recessed light fixtures should not be covered with insulation. The constant air flow produced by these fixtures can cause them to overheat, which could ignite the insulation and lead to a house fire. This can be avoided by installing insulation at least 3 inches away from the bottom of recessed fixtures.
