 The Home's Outer Shell (Exterior) Shelter is the task of a house's exterior shell: the roofing, siding, windows, doors and related components that provide a barrier between indoors and outdoors.
Today's houses are designed to provide somewhat semi-transparent shelter--the comfort and safety of enclosure without the feeling of being "closed in." To this end, houses incorporate plenty of windows, doors and skylights to bring in natural light, views and a sense of connection with the outdoors. Roofing, a key part of the house's shell, consists of several components. Finish roofing, roofing felt, and sheathing--in concert with flashing and gutters--create the waterproof surface. Exterior walls are faced on the outside with some type of durable siding. Beneath the siding, there is often building paper or a house wrap and, depending on the kind of siding, sheathing. Insulation provides an additional barrier to the movement of heat through a wall.
