9 Insulation
Baffles are a great way to increase airflow in your attic space. The formation of condensation at roof-to-attic contact points is more common in winter. The climate and the slope of the roof are both factors that can influence the formation of condensation. You can prevent roof deck condensation by installing baffles within every cavity.
To start an attic baffle installation, begin by measuring the space between your rafters. Attics and More says that you'll need to measure a rafter to determine its size and then plan to spread them out about 4 inches apart. Place your baffles between the rafters, making sure that they do not touch the attic ceiling. Place the first one next to your first soffit vent and staple it right onto the roof deck. If your attic has knee walls on the lower sections, install the baffles where the drywall attaches to the rafters.
Attic and roof insulation baffles can also help with stability issues by preventing insulation from entering walls where they're not supposed to go. This is beneficial for homeowners who want an effective insulation system without having their insulation enter into places where it doesn't belong such as exterior walls or floors, etc. For those who don’t know what attic insulation baffles are, they are insulation devices that are inserted in attics or roof spaces to prevent insulation from falling down.
