How do you install insulation baffles?

Pull any existing insulation away from the edges of the attic where you will be putting up the baffles. You will need a baffle for each space between the rafters. Fit each one snuggly in the bay, with the bottom starting where the ceiling joist meets the roof rafter.

Simply so, how do you install baffles?

  1. Determine the size baffles you need by measuring the space between your attic's rafters.
  2. Position the first baffle.
  3. Continue installing baffles, moving up the rafter bay towards the peak of the roof.
  4. Seal the baffles.
  5. Install insulation in each rafter bay over the baffles, following the manufacturer's directions.

Additionally, do you need baffles with batt insulation? baffles are basically used to make blow in insulation easier. You don't need them, but it makes it easier to maintain the air channels from the soffits to the roof. Without them, you need to be careful not to full the soffits with instulation when blowing.

Consequently, how do you install attic insulation baffles?

To install the rafter vents, staple them directly to the roof decking. Rafter vents come in 4-foot lengths and 14-1/2 and 22-1/2 inch widths for different rafter spacings. Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor.

Are attic baffles necessary?

Rafters. If you want to insulate the rafter bays rather than the attic floor in order to make the attic a heated space, baffles are even more important for proper air circulation. Baffles establish a channel for air to circulate between the insulation and the roof sheathing.
