Why is attic ventilation so important?
A. Attic’s act as an air space between the sun and our living area. Attic’s afford us a buffer so that we have some control over the amount of energy we need to live or work in a comfortable environment. In a multi-story building, each floor serves to accomplish the same thing. Most existing housing in this area is single story. Allowing the attic to “breath” so to speak creates a buffer space between the suns heat and the A/C setting in our homes. There are various materials on the market that contribute to this end. Fiberglass insulation slows the penetration of heat through our ceilings. The way it does that is by creating stagnate air within the fiberglass. Air is a fairly good insulator against heat when not moving. (Just the opposite is true when the temperature is too cold) Radiant barrier helps prevent heat from entering the attic. Tile roofs have an air space between the tile and the underlayment. This adds yet another air barrier. Mostly allowing attic air to vent is the best
