Best Attic Fan Covers: Full Buyer’s Guide & Why You Need One

When you have an attic, it is important to know what insulation is in place and how well it holds up against moisture. It’s also important to keep the air circulating, so mold doesn’t start growing. If you want something that will hold up, don’t worry about choosing between metal or plastic because they both work great!

Attic fans help regulate temperature by blocking out excess heat during the summer months or trapping cool air when outside temperatures drop. You can also use Attic fan covers to ventilate a room without opening windows, which is great if you’re worried about security.

Attic fans with vents are often overlooked despite having many benefits in favor of other cooling solutions like AC units or traditional ceiling fans. Let us look at a few of the most common types of attic fan covers on the market today and provide tips for choosing the right one for your needs.

Plastic Attic Fan Covers

The best plastic attic fan cover will have a non-attached frame that can be placed on top of your fan while giving you optimal access to change or clean the air filter. This type of cover (usually made from mesh) means there is no obstruction between the fan and the elements. 

Many people prefer to have plastic fan covers during windy days or when the ground is covered in snow. Some of the best plastic attic fan covers are:

Metal Attic Fan Covers

The best metal attic fan covers will help protect your fan from the weather elements while also providing good ventilation. The product’s frame should be adjustable, so you can make sure there are no gaps or holes where air can escape.

The downside of open models is that there’s no protection against UV rays (unless you install an additional cover). You must pay extra attention to ensure the insulation around them remains undisturbed.

Louvered Attic Fan Covers

Louvered attic fan covers are a step-up from both open and enclosed models. They offer a variety of benefits by providing excellent airflow, protection against UV rays, weather damage, etc., but still have openings that you can open to allow for ventilation if you need it.

There are many sizes and types of attic fans, but they can all be categorized into three main types: whole-house fans, gable fans, and ridge vent fans.

Whole house fans

These fans are connected to the power supply of the house, and they are either controlled by a switch or by the thermostat. Whole house fans work best in homes that have high ceilings, say 17 feet or higher.

Gable fans

These are smaller than whole-house fans since they are not connected to the power supply of the house. They are placed in an open gable area and cooled by the breeze circulating the home. Gable fans work best in homes with lofts and garages, like multi-story homes or double-story homes.

Ridge vent fan

These fans do not have a blade and usually look like a metal strip. All it needs is a ridge in your home for installation purposes so that you can place it in an enclosed attic. Since they do not have a blade, they are safe to use and perfect for homes with children or pets.
