Are attic baffles just installed at soffit venting.

The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents. What you ll need putting baffles in your attic is a crucial step in installing attic insulation. If you have continuous soffit vents install baffles in enough or all the spaces to give you the needed square footage of vent area. If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air.

Baffles ensure proper airflow into your attic space. Complete coverage of the attic floor along with sealing air leaks will ensure you get the best performance from your insulation. Baffles are installed in the attic or should be wherever there is an intake vent soffit vent. Raft r mate attic rafter vents have a high resistance to moisture which means they will not deteriorate over time.

Without baffles you must keep vents clear of insulation which means. Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent. Baffles and rafter vents are the same things. A soffit vent is simply a vent installed into the underside of your home s eaves called the soffit that permits fresh outside air to be drawn up into the attic.

Rafter vents or insulation baffles install in any rafter space to create narrow gaps that direct fresh air from the soffit vents to the peak of the roof. Space the soffit vents out so they divide the attic area into equal areas. Baffles prevent vents from getting clogged by insulation and ensure a clear channel for outside air to move into the attic through soffit vents. If there s blown in insulation like ours rake back the fluffy stuff with a 3 or 4 ft long 1 x 6 or use a garden rake or hoe.

The answer is rafter venting. To completely cover your attic floor with insulation out to the eaves you need to install rafter vents also called insulation baffles. When insulating your attic it is important that you have unrestricted flow of fresh air from the soffit to the attic. Baffles are only needed in the rafter joist spaces where soffit vents are located.

Installing baffles from a soffit vent and up the rafter bay allows you to insulate every available inch of attic floor space.
