Best way to baffle air in attic.

Pull any existing insulation away from the edges of the attic where you will be putting up the baffles. Some of this water vapor rises into the attic. You can situate the baffles where the circulation is mainly required. The faster the wind moves over the baffle the greater the pressure it creates.

Rafter baffles should be installed before dry wall or insulation. Proper air circulation in the attic is all about preventing moisture buildup. Be sure to wear long sleeves goggles and a dust mask. Surprisingly even the most well insulated attic space may still require the assistance of attic baffles to provide the additional air circulation.

The preferred way is for the baffles to begin above the ventilated soffit and extend all the way to the small attic above the second floor ceiling. To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space. You will need a baffle for each space between the rafters. The deeper the insulation the longer the baffles have to be.

During the summer soffit. Fasten blocking around the hatch or door to allow the material to be installed around this area without escaping. Baffles should fit snugly between your rafters and extend from just over the vent at the wall plate up the rafter. How important is using baffles in attic insulation.

Install air chutes in each rafter space to keep the air path clear between the rafters and the roof sheathing. In the summertime the outdoor air temperature as well as the air inside the attic is warmer than it is in the winter and warmer air can hold more moisture than cold air can. If you are finishing the entire attic space place the baffle directly adjacent to the soffit vent so air vents directly into the tray of the baffle and is captured against its bottom. Rafter baffles are sheets of plastic foam or cardboard that fit between the rafters in your attic to prevent moisture accumulation and add insulation to your home.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. The main function of an attic baffle is to draw the air in from outside your home and allowing it to circulate around your attic. Coat your arms face and neck with talcum powder to reduce the itching from insulation staple the chutes in place. Wind can blow up through soffit vents disturbing insulation and moving it out of place.
