Attic Baffles For Blown In Insulation

How to keep blow in insulation out of soffits 1.

Attic baffles for blown in insulation.

Atticat expanding blown in insulation is designed for your attic insulation project in new or existing homes. Set the baffles inside the attic opening along with a loaded staple gun. This way you can blow insulation into the roof or lay batt insulation without having to worry about the insulation getting into the soffit and blocking the soffit eave vent. Putting baffles in your attic is a crucial step in installing attic insulation.

Lay strips of 3 4 inch plywood that are at least 24 inches wide across the floor of the attic. Baffles are a critical component to our attic insulation process that provides multiple benefits to a difficult construction aspect. Sometimes called rafter vents baffles provide ventilation and keep the insulation from blocking airflow through your attic. For the same reason insulation shouldn t touch the roof s underside.

Baffles like this allow you to quickly ensure the soffit eave ventilation area is unobstructed and an air pathway from the eave vent is continuous into the attic cavity. Baffles provide a channel for air to flow through certain parts of the attic. Baffles are chutes that when installed properly can provide a channel for air to flow from your exterior soffit vents up into your attic space. The baffles make sure that the blown in insulation stays put so there s no wind washing.

The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. You d need a thickness of. In order to make this kind of roof assembly work insulation baffles or insulation chutes are necessary especially if the attic is going to have any kind of significant amount of insulation in particular blown in insulation that could potentially move around and block off the soffit ventilation from the attic thereby short circuiting air flow from the soffits through the roof s ridge vent. They will also allow us to maximize our blown in insulation without worrying about obstructing the air flow.

Typically made from polyvinyl. Basic functions of baffles. Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away. The attic insulation baffles that we ll be installing will make sure that there s adequate air flow from the soffit vents.

You need one baffle for each of the soffit. Baffles are also called wind baffles venting chutes rafter vents or insulation baffles. Don t be baffled by baffles.
