Propper Attic Ventilation With A Ridge Vent

Installation of this type of attic ventilation involves leaving a gap in the sheathing along the ridge and covering it with a perforated vent.

Propper attic ventilation with a ridge vent. Continuous un blocked soffit or eaves intake venting combined with continuous roof ridge venting or equivalent area if the building framing does not permit a ridge vent are needed to avoid ice dams attic condensation attic mold rot or insect damage from accumulating attic moisture. Combining an attic power vent fan with a ridge vent is usually not recommended because. To install the rafter vents staple them directly to the roof decking. Soffit vents come in several sizes and styles including small round discs and rectangular grilles.

Rafter vents come in 4 foot lengths and 14 1 2 and 22 1 2 inch widths for different rafter spacings. Prior to installing the ridge vent a 1 inch wide strip of roof decking is cut out along both sides of the ridgeline to allow for air movement through the vent. 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. Soffit vents when paired with ridge vents provide complete ventilation for your whole roof surface.

It is important that air movement occurs and is not impeded by any framing members of the home. A ridge vent is a ventilation strip that is placed along the ridgeline of the home. These vents allow outside air to enter the attic at the lowest point of the roof along the underside of the eave. These vents are laid along the ridge of the roof and can come as a series of separate pieces or one long piece.

They re most effective when used in conjunction with a continuous ridge vent. While this provides an outlet for air flow it does not provide an inlet to complete the convection cycle needed for proper ventilation. It could reverse the natural flow of hot air out the ridge vent. Static vents often protrude from roofline thanks to.
