Are Insulation Baffles Necessary
Measure the space between your roof rafters to determine how big you need to install an attic baffle. According to Attics and More, you will need to measure the rafter in order to determine its size. Then plan to spread them about 4 inches apart. Your baffles should be placed between the rafters. The first one should be placed next to the first soffit vent. Finally, staple it onto the roof deck. Install the baffles at the points where the drywall connects to the roof rafters if your attic has lower sections with knee walls.
Baffles act as a barrier between the conditioned area and the unconditioned area, preventing insulation from getting into any unwanted areas such as walls or exterior walls. Baffles can allow airflow to continue and maintain an insulated space at any time.
