Also known as rafter vents, baffles are installed in the attic to allow for proper airflow. Insulation baffles help get rid of the stale smell that comes from attic spaces. As counterintuitive as it sounds, even with insulation, it’s essential to have vents in the attic for proper aeration, especially if you plan on converting your attic space.
How Do Baffles Look Like?
Baffles are mainly made of rigid foam and come in lengths of 4 feet and widths of 14.5 or 22.5 inches. The sizes vary depending on the size of the rafters on your ceiling. Baffles come in tan, green, or blue colours depending on your preference. Usually, baffles are placed in between the rafters at the intersection of the ceiling and the attic floor.
How Much Do Baffles Cost?
Baffles may cost anywhere between $ 1.70 and $2 per square foot, depending on your supplier’s location and choice. If you are in Canada, the cost may range between $2 and 3 Canadian dollars per square foot of baffle.
How You Install Insulation Baffles
The process of installing baffles in the attic is simple, and you can do it yourself in an afternoon or during the weekend. Here are the steps to follow.
Rafters are constructed such that they leave spaces in between them. As a standard, baffles come in widths of 14.5 or 22.5 because those are the decking spaces’ standard measurements. You want to make sure that you buy baffles that snugly fit between your rafters by purchasing the right size.
Next, you want to place the insulation baffles adjacent to the air vents. By doing so, you want to facilitate airflow by trapping it on the baffle’s tray. If your attic space has knee walls, you need to staple the baffles directly to the roof decking.
Place baffles in a way that they over wrap each other and staple them together. Repeat the process on each rafter moving from the bottom to the area near the peak of your roofing. Do this for each rafter until the whole attic space is covered.
What Insulation Baffles are Used For
Insulation baffles are ideal for use in ventilated attics because they prevent the soffit vents from clogging with insulation. Baffles therefore facilitate airflow in and out of the attic space thus making the space more comfortable. Besides airflow, baffles also help to expel moisture from the attic so that mold and mildew don’t grow.
What is a Ventilated Attic System?
What do you relate an attic with? If you relate it with a musty smell, then it means it doesn’t have proper air circulation. A ventilated attic has vents that allow in air and also facilitate expulsion of hot air from the attic.
Naturally, hot air rises and if you don’t have proper ventilation, it’s likely to condense on the roofing causing mold and mildew issues. If you don’t have vents in your attic, your air conditioning system may also have to work extra hard especially during summer when the air is hot. This means that you’ll spend more on energy bills.
Why would you want a Closed Attic System?
A closed attic system can make your attic more comfortable and useful. It doesn’t have to be that damp room where you go and get out with an irritated nose. Here are some of the ways you can make use of a ventilated attic.
If your attic is dry and free of musty smells, you can convert it into a storage area. Instead of cluttering other parts of the house, the attic could be your go to place when you want to store items for future use.
