Easy Process Of Venting A Vaulted Ceiling
A vaulted ceiling is a kind of ceiling that usually provides you with open living space directly underneath the rafters, due to the fact that there are no horizontal ceiling joists. In spite of the fact that you don't have a separate attic to vent, air circulation is still necessary in order to keep heat away from building up between the bottom of the roof deck as well as the interior drywall finish. A vaulted ceiling usually consists of angled rafters that rest on wall plates before connecting at the top to a ridge beam. The thickness of the ceiling is entirely dependent on the size of the lumber that is used to construct the rafters. For instance, if the rafters are 2-by-10 boards, then each rafter cavity will be 10 inches deep. Due to the fact that there is no other available space, the rafter cavities are used for both insulation as well as venting purposes.
Intake Or Soffit Vents
- The underside of each rafter cavity ends at the soffit, which is usually parallel to the plane of the horizon that lies just underneath the roof's overhang. There are two choices that homeowners has when it comes to installing soffit vents, which will generally function as the intake vents for the roof. A solid soffit board, with individual soffit vents installed underneath every rafter cavity is permissible. However, it is often easier to install a vented soffit featuring a continuous, perforated vent.
Rafter Vents
- Rafter vents, also known as "rafter baffles" are usually long as well as shallow & are as wide as the rafter cavities. They are placed or fixed at the bottom of the roof deck, between the rafters, and stretch or elongate from the soffit all the way to the roof ridge. Make sure to use a rafter vent per rafter cavity. As soon as the rafter vents are in place, you can easily fix or place batt or rigid foam insulation before finishing the vaulted ceiling with drywall.
Ridge Vents
- The cool as well as a dry air that comes in the soffit must also has a place from where they can exit. When it comes to a vaulted roof, a ridge vent usually functions as the outtake or exhaust vent. A ridge vent consists of an open strip through the length of the ridge where the air that comes in the soffit can escape. A thin, perforated vent, over hanged with ridge shingles, hides the ridge vent when viewed from the street. Even when the sun beats ferociously on the roof, the cool, fresh air comes in the soffit vents and flows upward as well as out of the ridge vent. This cools the bottom of the roof deck, which in turn removes the heat as well as moisture that could otherwise damage the roof.
Gable Vents
- Some vaulted ceilings don't have individual rafters, however, they consist of pre-engineered trusses. Vaulted roof trusses are, to a small degree, misleading, due to the fact that the vault degree on the exterior of the roof is not the same as the vault degree inside, which is substantially less. Although the ceiling still vaults, there is a lot of space betwixt the drywall and the top chord of the roof truss. Venting a roof with vaulted trusses needs the installation of soffit vents as well as the addition of at least two gable vents, placed as high as possible on the sidewalls, in order to allow fresh air from the soffit to escape.
