the exterior walls surfaces of a building form the skin of the building. These surfaces or building components are commonly referred to as cladding. The purpose of the cladding is to provide the building with a weather resistant exterior wall envelope.
The majority of building envelope failures can be attributed to water in one of its many forms - gas, liquid, or solid. Water degradation can take the form biological degradation, freeze -thaw cycles, high relative humidity, water ingress and absorption.
A Building Envelope is the separation between the interior and exterior environments. It is the outer shell, or elements including the foundation, walls including windows and doors, and roof. Proactive maintenance is necessary to preserve and protect the envelope and extend its durability.
The importance of incorporating durability into the construction of homes and buildings is important to prevent premature failures and building deterioration. Building envelope performance and longevity are important factors.
