Building Envelope Systems
The building envelope serves as the primary barrier between conditioned interior spaces and exterior environmental conditions. Effective envelope design addresses thermal performance, moisture management, air leakage control, and structural integration.
Key considerations include insulation materials and placement, vapor control strategies, air barrier continuity, thermal bridging mitigation, and window/door assembly performance characteristics.

Insulation and Thermal Performance
Thermal insulation reduces heat transfer through building assemblies and contributes to energy efficiency, occupant comfort, and condensation control. Insulation materials are characterized by R-value, which measures resistance to heat flow.
Common insulation types include fiberglass batts, mineral wool, spray foam, rigid foam boards, and cellulose. Installation quality significantly impacts thermal performance, with attention required for compression avoidance, gap elimination, and air barrier coordination.
