The continuous layers make up the barrier that helps to keep your home warm and dry.Īir sealing, including caulking and weather stripping, are a cost effective way to reduce the amount of air leakage in your home. This, in turn, will reduce the energy efficiency of the home. If one of the barriers is insufficient, it affects the other barriers. All barriers play unique roles as part of the building envelope. All of these layers work together harmoniously. The building envelope is made up of multiple layers of barriers: air barrier, vapour barrier, thermal barrier, weather barrier, and interior/exterior finishes. Essentially, it is what protects you from the harsh elements - rain, snow, wind, and sun. What Is A Building Envelope?Ī building envelope is what separates conditioned and unconditioned space in a home or building. This results in reduced overall performance, reduced energy efficiency of the home, and increased utility bills. Again, if there are any holes or leaks in the home, it will notably increase the need for your mechanical system to continuously run in order to keep your home comfortable. The building envelope is also concerned with the technical performance of the home. Therefore, if there are any holes or leaks in the building envelope, you are significantly reducing the overall energy efficiency of the structure. The building envelope is what separates conditioned and unconditioned space. The building envelope is one of the most important pieces of your home, and one of the most important aspects in achieving overall home energy efficiency.
