Vaulted Ceiling Insulation Air Gap

The craze for insulated cathedral ceilings and great rooms really took off in the 1970s and 1980s when examples began popping up like mushrooms after a warm rain.

Vaulted ceiling insulation air gap.

It provides an open airy look and feel to the room and they are often in demand among home buyers. Air sealing and insulating. These are brand new condominiums and we ve insulated according to the builders specification with fiberglass in the walls and we re going to be blowing the flat of the attic space with cellulose along with the rafter spaces in the cathedral ceiling. This type of roof assembly is designed so the air can flow up the soffit vent through an insulation baffle pass through the 1 5 gap between the insulation and roof sheathing then exit through a ridge vent.

In those days most builders stuffed cathedral ceiling rafter bays with fiberglass batts. Vented cathedral ceilings can be difficult to insulate well. Ventilation channels maintain an air gap between the insulation and the roof sheathing. Cathedral ceilings are a feature in many homes that add to value to the house because the high ceiling tends to make rooms look larger.

Insulated cathedral ceilings are a relatively recent phenomenon. In a vaulted ceiling however the only fresh air route lies between the insulation and the underside of the roof deck. The component that creates the gap is called a variety of things including a ventilation baffle a ventilation chute a ventilation channel or a product such as proper vent.
