Blocked or inadequate roof ventilation air intake openings at soffits or eaves.
Problems of wind washing in the attic from eave vents.
How to prevent wind washing in new construction.
See the guide attic eave minimum insulation.
Air seal cantilevered floors.
Roof turbines have blades that spin in the wind pulling air up through the intake vents into the attic and out of the house.
Wind blows over the ridge and pulls heated air and moisture from the attic creating a uniform air movement that eliminates hot spots.
Kitchen and bath fans vented into the attic.
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.
Some ridge vents have a baffled ridge.
The dual function design creates ventilation channels under the roof sheathing for healthy air circulation while integral baffles prevent wind washing.
See the guide cantilevered floor.
Rectangular roof vents installed on one side of the roof only.
This article explains the effects on buildings caused by locked soffit intake vents and we explain how blocked soffit venting causes or contributes to attic condensation moisture and potential mold contamination problems in buildings.
See the guide unvented attic insulation.
One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home.
Vent these fans through the roof or soffit.
Or design the home with an unvented attic.
