The Best Attic Baffles Reviews In 2021

Baffles help to provide proper airflow into your attic space. If you’re thinking about installing the best attic baffles in your home, you need to ensure that you have an intake vent (soffit). This is because baffles prevent vents from getting clogged by insulation, and they also ensure a clear channel for air to perfectly move into the attic through the soffit vents.

Baffles are quite critical in the insulation process of an attic. When you install them properly, you’ll experience a wide range of benefits, especially during the winter season when homes are more susceptible to the formation of condensation. There are plenty of attic baffles out there and trying to decide the best option can be overwhelming.

Luckily, we’ve come up with a list of 6 of the best attic baffles you can buy to ensure the best performance and experience. See these reviews below.

What Are Attic Baffles?

Attic baffles are chutes that, when you install them properly can offer you a channel for air to flow from your exterior soffit vents, and up into your attic space. The main purpose of that airflow is to churn the stale air in your attic and thereby assist in removing moisture and controlling your attic’s temperature.

Baffles are designed in different materials such as plastic, cardboard, and even foam. The foam baffles are known to hold humidity while the cardboard baffles tend to absorb moisture, which causes them to fail and become ineffective. Baffles help to provide airflow in your attic and keep it insulated off your roof deck. 

Types of Attic Baffles

The most commonly used types of attic baffles include:

  • Styrofoam rafter vents – These types of attic baffles resemble egg cartons and feature extra cones to help keep the air vents open. 
  • Cardboard baffles – These baffles are cheap but now highly recommended, especially if you happen to stay in areas like Nevada and Arizona. They don’t perform well in low-humidity areas. 
  • Plastic baffles – These are some of the best attic baffles recommended out there. What makes them ideal is that they are stiffer and can withstand the pressure from the insulation that is being blown into the attic. This is especially sprayed foam insulation. They are also efficient, lightweight, and durable.

Are Baffles in Attic Necessary?

An insulated attic requires proper airflow, and you need to remember that your attic’s airflow comes from the outside and is then pushed underneath the roof and out of the vent.

The baffle is the one that provides a space for the airflow without being blocked by insulation. Baffles are normally installed in the attic to provide you with proper airflow into the attic space. 

Another thing that makes baffles necessary to have is that they prevent vents from getting clogged by insulation. When you prevent moisture buildup in your attic it helps in ensuring that there’s proper air circulation. Therefore, baffles are necessary for your attic, if you want proper air circulation.

How Many Attic Baffles Do I Need?

During the summer season, most people need to keep their attic cooler and the benefit of this is that it can increase the life of the roof, and also save money on air conditioning bills.

If you want to efficiently cool your attic, you need to ensure that outside air circulates through it. One good solution for this is using the best attic baffles. You should have at least one baffle between every rafter/truss.

As a general rule of thumb, you need to keep in mind that the total amount of attic vent space you need is at least 1 sq ft of attic baffle for every 150 sq ft of attic area. That means you need to calculate the total vent area that you need, to ensure you have accurate measurements.

How Long Should Attic Baffles Be?

The most recommended length of attic baffles is 4 feet, but you also have the option of trimming your attic baffle if necessary. Having an attic baffle comes with a lot of benefits, with the main one being the fact that it provides proper insulation and airflow into your attic space. 

When thinking about installing attic baffles, you first need to measure the area where you’re planning to set them up to ensure everything is well prepared. Baffles come in different shapes, sizes, and materials.

Therefore, it’s important to familiarize yourself with this information before embarking on the process of installing attic baffles in your space.

How Much Does It Cost to Install Attic Baffles?

This is one of the most sought-after questions regarding the best attic baffles that you can install in your home. Similar to everything else, the cost of installing attic baffles can vary from one place/expert to another.

One common factor is that the installation price may range from $0.75 to $1.20 per square foot, or even more. This price includes the material, labor costs, and profit. 

When it comes to installing roof vents, the cost can range from $300 to $650 including the labor and material. The installation costs are highly influenced by the size, type, and a number of units that you want to install.

Ridge vents can cost between $2 and $3 per linear foot. The cost of roof vents, on the other hand, can range from $10 to $500 depending on the style and size.

To properly install attic baffles, you need to directly staple them to the roof decking. This will ensure they are effective enough and perform better in reducing insulation and circulating air efficiently.

How to Install Attic Baffles

It’s not just about buying the best attic baffles, but also knowing how to install them properly to be effective. Installing attic baffles requires the utmost scrutiny or the assistance of a professional.

However, if you want to do it yourself, here are the simple steps you need to take.

  1. First, you need to find out the size of baffles you need. You can do that by measuring the space between the rafters in your attic. This will help to give you precise measurements.
  2. Take the first baffle and position it properly. If you’re completing the entire attic space, you can place the baffle adjacent to the soffit vent.
  3. Continue with the process of installing the baffles and move up the rafter bay toward the roof’s peak.
  4. Once you’re done with the third step, go ahead and seal the baffles.
  5. The final step involves installing insulation in each rafter bay over the baffles, but you have to follow the instructions provided by the manufacturer.

Attic Baffle Alternatives

Some good alternatives to attic baffles include house wrap and foam. What makes house wrap an ideal alternative to consider is that it can act as an air barrier and help to reduce air filtration, unwanted moisture into roof cavities, and still maintain the performance of the insulation. However, the drawdown to using a house wrap is that it’s not much reliable.

The other option is to use sheets of rigid foam insulation, which are cut score on a table saw to easily bend and form a chute. This process requires you to be keen, but the best way is to seek a professional or another pair of hands to help you in the process.
