Venting & Ventilation

Home Insulation Contractors – Minnesota

A properly vented attic is very important. Inadequate venting in your attic causes all sorts of problems, from wood rot to mildew, peeling exterior paint, rusty nails/screws, roofing problems and even energy loss. The good news is that it can be easily prevented by simply venting your attic correctly.

For attic ventilation to be effective, outside air should enter the attic low at the attic perimeter, and exit high near the attic peak or roof vents.

Most attics require air chutes to circulate proper air flow. Air chutes are placed between the rafters in the attic, and go down into the soffit to bring up proper air flow. The size of the attic determines how many air chutes are recommended for optimal venting.

Soffit vents are installed under the eves on your home as the “intake” vent. They provide air flow through the air chutes into your attic. To avoid moisture problems in the attic, the air chutes must remain unblocked by insulation , and the soffit vents need to be open and clean to make ventilation work properly.

A well-ventilated attic will create a cooler attic in the summer and a drier attic in the winter months. In the summer, natural air flow in a well-vented attic helps to release the hot air out of the attic. Proper ventilation helps to keep a more uniform temperature on the underside of the deck in the winter, and that will help to eliminate one of the common causes of ice dams.
