Roof Sheathing Baffles

Brentwood s accuvent baffles for roof ventilation are designed to save energy for cleaner greener living spaces.

Roof sheathing baffles.

In order to make this kind of roof assembly work insulation baffles or insulation chutes are necessary especially if the attic is going to have any kind of significant amount of insulation in particular blown in insulation that could potentially move around and block off the soffit ventilation from the attic thereby short circuiting air flow from the soffits through the roof s ridge vent. Roofs often require ventilation channels directly under the roof sheathing either for a short section of the roof for example near the eaves or for the entire roof from soffit to ridge. When the wind is blowing these ventilation channels allow air to move from the soffit vents to the ridge vents. It is a simple yet functional design with the added bonus of keeping unwanted pests from entering your home.

Site built baffles have several possible advantages over manufactured baffles. When set into place and sealed with spray foam the vent baffles are insulated and air sealed. So why install a baffle. 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.

As with attic floor insulation moisture and heat removal are the reasons for creating proper air. They can create deeper ventilation channels for example and can be sturdier. The dual function design creates ventilation channels under the roof sheathing for healthy air circulation while integral baffles prevent wind washing.
