Using an attic cover helps insulate your attic fan and prevents air leakage. But buying a good attic cover can be confusing as there are several options on the market.

Buyer’s Guide – Choosing the Best Attic Fan Cover
Types of Attic Fans
You can use several different fan styles to help control the temperature and humidity of attic space. They have many different features, and depending on their layout, your attic may be better suited to one of the following types:
Whole-house fans are installed directly into the ceiling of the highest point in the attic space or an upstairs hallway. When running, they pull moisture and hear from inside the house and channel it into the attic space.
Attic Venting Fans
Attic fans serve a unique function by removing moist air from the attic and leaving the areas below the attic floor alone. These fans help circulate air within the attic, pulling fresh air from the attic vents and forcing hot air outside.
Moreover, attic fans serve a year-round function. In the summer, you can reduce the attic temperature and extend the life of roofing shingles and sheathing. In colder months, attic fans help prevent the damage caused by ice dams. The fans cool the attic space and equalize the temperature in the house.
When installing an attic fan, it’s crucial to consider how far your attic is from the rest of the house. You will need to seal it properly. If your attic door or hatch is drafty, then the fan will merely pull air-conditioned air through the gaps. You don’t want to increase energy bills, so it’s best to use an attic fan cover.
What to Look for When Buying an Attic Fan Cover
The problem with a whole-house fan is that the hot air needs an outside passage. If your attic isn’t ventilated properly, you can expect humid, moist air to build up and cause mold to grow. Therefore, whole-house fans are ideal for open, well-vented attics.
Here are some helpful tips to note when choosing an attic fan cover. You may want to understand the different capabilities and functions of covers and their construction material. And most importantly, you have to keep some safety considerations in mind before installing a new attic fan cover.
Your attic fan should be constructed from sturdy materials to survive the excessive heat and humidity. Cheaper attic fan covers with low-quality foam often get damaged over time under harsh weather conditions.
Choose a fan cover with high-quality foam and reflective material. The polyester material is an added benefit. These materials are more stable in fluctuating temperatures and hold up steady against moisture. They also provide excellent insulation and prevent air leakages.
Ease of Use
If you find it hard to install a fan cover, attic ventilation is of no use. Many whole-house models now come with self-adhesive tapes, which allow you to stick the vent cover and customize its size using a sharp razor or knife. You can also find attic fan covers with magnetic capabilities that don’t require professional installation.
One very important factor to consider when deciding if an attic fan cover is right for you is safety—particularly around furnaces installed in your attic. Avoid a fire hazard by installing a high-quality attic fan cover that reduces draft and prevents air leakages.
Frequently Asked Questions
If you aren’t entirely sure how an attic fan cover or whole-house fan cover works, here are some answers that might help.
Do attic fans or whole-house fans help?
Attic ventilation fans can help cool your attic by removing heat from inside the attic and bringing in cool air from outside, preventing hot, humid air from seeping into your home. Avoid putting excessive load on your air conditioner by installing an attic fan and cover.
Should I cover the attic fan in the winter?
You should leave your roof vents open in colder months – do not cover them! During the winter, roof ventilation works to equalize temperatures. Closing your vents makes the attic too warm and dry – ideal conditions for mold as well as insects.
How can I insulate an attic fan?
You can build an open-faced box from rigid foam insulation and place it on top of the attic fan. Cut out the foam pieces with a sharp knife and attach the pieces with foam insulation adhesive tape. Alternatively, you can buy attic fan covers reviewed in this article.
Are attic fans bad?
In worst-case scenarios, attic fans can create more problems than they solve if there are not enough gable or ridge vents. A powerful attic exhaust fan can force the air from your house through the ceiling if not sealed properly.
Do attic fans prevent mildew?
You can’t go wrong with attic ventilation. Air constantly moving through your attic will help prevent mold. Old homes never had mold because they were so drafty. Water vapor was transported outdoors or evaporated before mold could grow
You don’t need to buy an attic fan cover, but it’s a reasonable thing to do. You can save up on your utility bills by installing an attic fan cover.
