The idea of weatherization is to control the factors that cause the heating and cooling system from coming on during the winter and summer. Typical energy saving weatherization modifications include insulating walls, ceilings, and floors; sealing the air leaks throughout the home; maximizing window and door efficiency; and tuning or upgrading the heating/cooling system.
Weatherizing also refers to a systematic process of assessing the home’s thermal condition and tightness and its heating/cooling system to determine the most cost effective energy …
Do I need to insulate and weatherstrip the attic access door?
Yes, if the attic access door is within the living space and can open directly into the attic. Whether in a hot or cold climate, the access door should be treated just like an outside entrance door; it must be insulated and weatherstripped.
During cold and windy weather, heat loss and air leakage through uninsulated and non-weatherstripped ceiling openings is a major source of energy loss (resulting in higher heating costs). During the heat and humidity of the summer, where …
