Section 73 of 105
71. Air, Thermal, Moisture and Environmental Interfaces
Stable section ID: S05-CON-014-SECTION-73 · 20 content blocks
Environmental Interfaces shall maintain the required continuity of air control, thermal control, moisture management, drainage, vapor control, and environmental separation.
Specifications shall address:
- Airtightness.
- Thermal resistance and continuity.
- Thermal bridging.
- Vapor behavior.
- Bulk-water drainage.
- Capillary control.
- Condensation risk.
- Pressure differences.
- Airflow direction and capacity.
- Material compatibility.
- Movement and differential expansion.
- Weather exposure.
- Seal replacement.
- Inspection and drying access.
Environmental performance shall be evaluated at joints, penetrations, transitions, and assembly boundaries rather than inferred solely from the performance of individual materials.
Interfaces shall direct water toward safe drainage or drying paths. They shall not depend on permanently trapped moisture or inaccessible sealant as the only protective strategy.
Thermal and moisture behavior shall be evaluated for the applicable climate, occupancy, construction state, and service conditions.
Replacement or modification of a Cartridge, panel, utility, or finish shall restore the complete environmental control layers.
