High-Performance WRB & Air Barrier Installation

Installation of vapor-permeable exterior weather-resistive barriers and air barrier systems for high-performance wall assemblies.

We work with premium membrane systems such as SIGA Majvest® 500 SA to provide exterior weather protection, air-sealing continuity, and long-term durability of the building envelope.

Attention is given to sill, jamb, and head conditions, substrate preparation, transition details, and sequencing between interior and exterior layers to support long-term building performance.

Services include substrate preparation, membrane layout and sequencing, detailing around openings and penetrations, transition integration, seam sealing, and coordination with window installation and exterior insulation systems.

Our approach focuses on reducing uncontrolled air leakage while maintaining outward drying potential and weather protection for modern high-performance assemblies.
