Why Ventilate?

Summer heat, trapped in the attic, creates a furnace effect, heating ceiling insulation, which then conducts heat through to the ceiling, and this heat is then radiated downward to persons and objects in the rooms below. This is why it is much warmer upstairs in the bedrooms than downstairs in the basement!

Other problems that arise by this are the curling, or the bleeding of shingles, and the warping of the sheathing. The air conditioner is working continuously to cool down the living area.

why ventilate in summer
Winter conditions bring a different type of problem. During the cold months of the year, the air inside the home is warmer and carries more water vapour than the colder, dryer air in the attic.

Cooking, laundry, showers, humidifiers and other activities using water contribute to this condition. There is a strong natural force, termed “vapour pressure”, that causes water vapour to migrate from high-humidity air or materials to low-humidity air. This migration of water vapour passes through ceilings, insulation and wood and even successfully circumvents a vapour barrier. It moves into the attic space where it can readily condense into liquid water on the cooler structural members-rafters, trusses, and especially the cold roof sheathing.
