If you have insulation in your attic, you should also have intake vents. Typically, intake vents are installed at the eave or soffit. Intake vents allow external air to flow into your attic and expel stale attic air through exhaust vents placed higher on the roof. Intake and Exhaust vents help your attic to breathe.

If you have insulation in your attic, it is important that you prevent the insulation from blocking intake vents. Baffles also called rafter vents. attic baffles, insulation baffles, or vent baffles are designed to prevent insulation or other debris from blocking airflow into the attic.
HOW DO BAFFLES WORK?
When installed properly, baffles channel airflow up and over any insulation, into the attic. Baffles are typically made of foam and can come in different colors.
HOW ARE BAFFLES INSTALLED
Baffles are installed anywhere you have an intake or soffit vent in your attic. It is important that baffles are installed level and are properly secured.
ARE BAFFLES EXPENSIVE?
Baffles are inexpensive to install and the cost is easy to offset when you consider the costs and discomfort associated with cooling living spaces impacted by heat build up in your attic during summer months, and moisture related issues during winter months. Which can lead to mold and mildew issues.
BLOCKED INTAKE VENTS?
It can be difficult to tell if you have proper intake venting in your attic. Many homeowners that see vent screens at the soffit mistakenly assume they have attic vents. A vent screen without a vent hole into the attic isn’t providing the needed airflow. Fortunately, adding proper ventilation is an affordable attic upgrade. The following video demonstrates how the appearance of vent screens can be very misleading.
