Foam Insulation Baffles Before And After
Other baffles only provide insulation and don't account for the possibility that it can fall out. Because it fills all of the gaps, loose-fill insulation is best because it maximizes its potential, decreases moisture, and allows air flow (air circulation), more effectively. Baffles are required for insulation. If baffles are not installed, you could have areas that are too full or too thin. Baffles allow you to fill all the rafter space and keep insulation from filling unneeded areas of your crawlspace.
There are several different types of attic baffles available for sale today. Some are made to be installed under the floor on top of your crawlspace or over the joists, while others can also be used in your attic. An integral insulation baffle resists vertical airflow and is made of expandable material which will conform to almost any construction. It's easy to cut and install, just place it in the correct location and you're done.
Attic baffles are simple but effective devices that are used in all types of construction projects, both big and small. Their main function is to add support and stability to whatever they're installed in. Roof insulation baffles are most often used for this purpose when insulating homes or buildings by supporting fiberglass insulation. Fiber insulation is the most common material used in homes today.
