1. Moisture and Thermal Protection moisture is normality present in the interior spaces in the form of water vapor when water vapor reaches a surface cooled by heat loss to the colder outside air condensation may occur. According to Bulding constraction illustrated book to prevent water from leaking into a roof assembly and eventually the interior of a building flashing must be installed along roof edge. Wall flashing is instulled to collect any moisture that may penetrate wall and drop it ouside due a weep holes. And we have different types of flashing such as parapate flashing, spandrel flashing,and sill flashing. Masonry veneers can also be used as curtian walls sipported by steel or concrete frame. And also we have the Thermal isulation which is to control the flow or transfer of heat through the exterior assemblies of a building and thereby prevent excessive heat lose in cold seasons and heat gain in hot weather. Therefore we have ventilation wich is a system that provides fans for pulling stale air from the livinh areas. There is four different types whole house, energy recovery, roof and attic and crawl space ventilation.
