Insulation Baffles Installation Youtube
Bob Vila explains that attics are equipped with intake vents that allow in cool air. Hot air exhaust vents that vent hot air at the roof's peak let out hot. The intake vents may be placed in the soffit in one continuous piece or separated by vents every few feet. The vents on gable roofs will be closer to the peak of their gable.
Rafter vents, also known as insulation baffles, are required to completely cover the attic floor. To get the best insulation performance, you need to cover the entire attic floor and seal any air leaks. Rafter vents make sure the soffit vents at the roof are clean and allow outside air to flow through the ridge vent or gable vent. Attach the rafter vents directly to the roof decking. For different spacings, rafter vents are available in four-foot lengths as well as 14-1/2 or 22-1/2-inch widths. You should place rafter vents in your attic ceiling between the rafters where your attic ceiling meets the attic floor.
Exhaust vents are installed at the top of the roof. Their primary job is to provide an unobstructed exit for the heat, hot air, odors and moisture trapped in your attic. Baffles and rafter vents are the same things. Baffles (often called rafter vents) are installed in the attic, wherever there is an intake vent (soffit vent). Baffles prevent vents from getting clogged by insulation and ensure a clear channel for outside air to move into the attic through soffit vents.
