It may seem contrary to add attic ventilation whose purpose is to provide warmth and them allowing cold air to pass through the vents of the attic but it is a great combination to ensure you have an energy efficient home. In the winter, keeping the attic cool reduces the odds of causing ice dams and the correct insulation as well as air sealing blocks heat entry and moist air from below the attic. In summer, the natural flow of air removes over heated air from the attic, helping to protect the roof and causing less damage to the house. Read on to learn more.
Attic Fan Insulation
These work by draining in the cooler air from attic vents and by pushing warmer air to the outside. But if your attic has blocked soffit vents and is inadequately sealed the fans will suck up the conditioned cooled air taking up more energy. You do not want this to occur!
What it Takes
Laying fiberglass rolls is easiest for a DIY job. If you have any type of insulation between the rafters, install the second layer over and perpendicular to the first (again, the second layer of roll insulation should be unfaced — with no vapor retarder). This will help cover the tops of the joists and reduce heat loss or gain through the frame. Also, when laying down additional insulation, work from the perimeter toward the attic opening. Never lay insulation over recessed light fixtures or soffit vents. Keep all insulation at least 3 inches away from “can” lights, unless they are rated IC (Insulated Ceiling). If you are using loose fill insulation, use sheet metal to create barriers around the openings. If using fiberglass, wire mesh can be used to create a barrier.
Rafter Vent Installation
To completely cover your attic floor with insulation out to the eaves you need to install rafter vents (also called insulation baffles). Complete coverage of the attic floor along with sealing air leaks will ensure you get the best performance from your insulation. 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. 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.
