Building Envelope
The building envelope refers to the complete physical barrier between the interior of a building and the external environment, including the roof, walls, insulation, windows, and waterproofing systems. In roofing, the roof assembly is a critical component of the envelope, responsible for controlling heat, air, and moisture transfer. In Vancouver’s wet and humid climate, a well-designed building envelope is essential to prevent water intrusion, mold growth, and energy loss. Roofing systems must integrate seamlessly with flashing, insulation, and ventilation to maintain envelope integrity. A failure in any part of the envelope can compromise the entire structure’s performance and durability.
