What is a ventilation baffle?
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. That airflow is intended to churn the stale air in your attic which helps to remove moisture and control the temperature of your attic.
What is the purpose of an air baffle?
Baffles allow mixing of air streams inside a building and increase the air velocity in the freestall area. An excessive static pressure drop reduces the efficiency of a fan. Proper baffle design limits the total static pressure drops across the inlet and baffles to 0.15 inches of water or less.
What is AtticMate?
Owens Corning’s AtticMate Attic Vent product is a polystyrene sheet shaped to create an air channel in the cavity between the insulation and the roof deck. AtticMate Attic Vent prevents the attic or rafter cavity insulation (batt or blown) from expanding to fill cavity airways and restricting airflow.
Does every rafter need a baffle?
Keep in mind not all rafter need baffles, just those with intake vents at the soffit. If you don’t have baffles installed, check your intake vents for any type of blockage for insulation or debris.
How does baffle work?
Baffles work by disrupting the flow pattern and providing top to bottom flow. By ensuring that top to bottom flow is achieved in addition to swirling flow, baffles are able to prevent this from happening.

Why does accuvent need to be installed in Attic?
AccuVent acts as an all-in-one wind-wash barrier and vent. Without a wind-wash barrier, air enters the attic freely and flows above the insulation in the ceiling, greatly reducing its R-Value. This can cause moisture buildup… Please leave this field empty.
