For the same reason insulation shouldn t touch the roof s underside.
Insulating attic with gable vents.
The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.
Soffit vents sit underneath the eaves of the roof of a house to allow air circulation into the attic.
Never cover attic soffit vents with insulation use rafter vents and soffit vents to maintain airflow.
Installation of this type of attic ventilation involves leaving a gap in the sheathing along the ridge and covering it with a perforated vent.
The air is then exhausted through gable.
Before insulating vaulted attic walls you must provide an unobstructed route from the soffit vents to an exit vent to prevent damage to the roof from moist hot air.
Static vents often protrude from roofline thanks to.
Attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents soffit and gable and pushing hot air to the outside.
