Shop rafter vents and a variety of building supplies products online at Lowes.

Install the ventilation system between rafters to provide an air channel through insulation to help keep air flowing freely from soffits to ridge.

This can lower your utility bill by as much as. Start saving with V-Baffle. These attic baffles are lightweight, easy to install and provide excellent airflow.

Our cardboard attic baffles are 24″ wide with bendable tabs to fit within a 24″ truss. Choose an option x x x x 44. The baffle may then be stapled to the truss to hold them in place. My solution was to make bricks of rigid foam insulation, attach them to the baffles with double-sided tape, and then use a small rake to push them into place.

Brentwood’s AccuVent baffles for roof ventilation are designed to save energy for cleaner, greener living spaces. The dual function design creates ventilation channels under the roof sheathing for healthy air circulation while integral baffles prevent wind-washing. AccuVent offers a quick and inexpensive solution for architects, builders, and renovators to ensure proper insulation performance for better energy efficiency and indoor air quality. Without ventilation channels, air cannot flow freely from the soffit to the exhaust vents.

Poor air flow reduces insulation efficiencies and accelerates problems due to moisture. Click on the video below to see how easy installation is. An attic with balanced ventilation has undereave or soffit vents, which allow fresh air into the attic.

The fresh air flows up between rafters to the ridge, where a ridge vent, roof vents or gable vents allow the air to exit. If insulation is allowed to bunch against the inside slope of the roof between the rafters, air will be blocked before it can traverse the attic. Generally speaking, you need a ratio of 1:30 where for every 3square feet of ceiling space, you need square foot of attic ventilation.

That sai air resistance and interference (such as vent grates) reduces the area of true ventilation. In other words, the entire vent opening doesn’t count as vented space. Finally, to ensure that the airway to the vent remains open, staple a ventilation baffle to the plywood sheathing in each rafter bay. The molded polystyrene baffles , available at home centers and lumberyards for about $each, form channels that hold insulation at bay and direct incoming air upward. The gable of your house must have openings to allow fresh air to enter and stale air to exit.

They are easy to install and are positioned along the inside of the roof deck. Air is channeled up and through the vent- passing through your insulation toward your exhaust vent. Easy to use, simple to install.

Baffles are a critical component to our attic insulation process that provides multiple benefits to a difficult construction aspect. BASIC FUNCTIONS OF BAFFLES Baffles are chutes that, when installed properly, can provide a channel for air to flow from your exterior soffit vents up into your attic space. Vent chutes that are also called baffles or rafter vents play an important role in your attic ventilation system. House attic vent chutes and their three important roles in attic ventilation : vent chutes provide unobstructed air passage between the soffit vents and the attic. If you’re insulating a ceiling and need to maintain an air-sealed vent space from the soffit all the way to the ridge, you could use plastic vent baffles stapled into place between the rafters and try to air seal them, but there’s a better way.

The success of a vented attic or roof deck relies on its airtightness. The space above the top plate of exterior walls—at the bottom of each rafter bay—is especially important. Baffles placed in this area channel intake air into either the attic space or vent chutes, and also prevent insulation from falling into the soffit and blocking airflow.
