Uncontrolled air leakage is the leading cause of energy loss and moisture damage in commercial buildings. CR provides advanced air barrier solutions that seal the building envelope, ensuring thermal efficiency and long-term durability.
We understand the building science behind air, water, and vapor transport. Whether the specification calls for a ‘breathable’ permeable system or a non-permeable vapor barrier, our trained installers ensure a continuous, monolithic seal that passes rigorous blower-door testing and meets California Title 24 energy standards.
CORE INSTALLATION CAPABILITIES
Fluid-Applied Systems:
- Vapor Permeable: “Breathable” coatings that stop air/water but allow trapped moisture to escape (crucial for occupied hospitals/schools).
- Non-Permeable: Vapor-blocking systems for specific climate zones and humid environments.
- High-Build Spray: Efficient application for CMU, concrete, and exterior gypsum sheathing.
Sheet & Membrane Systems:
- Self-Adhered (Peel & Stick): Consistent thickness membranes for critical waterproofing tie-ins.
- Mechanically Fastened: House-wrap solutions for rainscreen assemblies.
- Through-Wall Flashing: Integrated flashing systems to direct water out of the wall cavity.
Detailing & Transitions:
- Fenestration Tie-Ins: Air-tight sealing of window and door frames to the rough opening.
- Penetration Sealing: Detailing around pipe, duct, and electrical penetrations through the exterior wall.
ABAA STANDARDS & TESTING SUCCESS
An air barrier is only effective if it is continuous. We treat every square foot of the envelope as a critical system, eliminating the pinholes and bridging gaps that cause testing failures.
- ABAA Quality Assurance: Adherence to Air Barrier Association of America installation protocols.
- Envelope Commissioning (BECx): Coordination with third-party consultants during envelope testing.
- Film Thickness Verification: Wet-mil gauging during application to ensure manufacturer-required thickness.
- Adhesion Testing: Pull-tests to verify the bond to the substrate (sheathing, concrete, or steel).
- Substrate Prep: Ensuring sheathing joints are properly taped and fasteners are spotted before coating.
A tight building envelope is the key to energy efficiency and occupant comfort. Don’t risk mold issues or testing failures with an inexperienced crew. CR delivers the building science expertise to seal your structure right the first time. Contact us today to review your air barrier details.
