Handling heat loss in cathedral ceilings


A note of interest: If propa-vents are in place under the roof sheathing, they can remain. However, the general consensus among energy professionals is that no vents are needed. A solidly filled cathedral ceiling is fine as long as there is adequate whole-house ventilation. This ventilation can be provided by a simple bathroom vent fan that is on a timer and runs at continuous low speed.
