What is Building Envelope?
This is the exterior perimeter wall and roof of the building structure separating the indoor from outdoor environments. It encompasses the composite wall and roof structure, windows, doors and all penetrations through the exterior walls and roof. This may lead to further investigations of wall and roof sections. The building code indicates the construction of a building is to be “weather tight.” The so-called waterproofing or water shedding characteristics of a building’s envelope is vital for ensuring long-term structural integrity along with reducing the nuisance of leaks, interior damages and the likelihood for an environment that will foster and support mold or other biological growth.
