Exterior Envelope Systems
The building envelope is the most coordination-intensive scope on any commercial or multifamily project. NBS designs and delivers the complete wall assembly system — from structural sheathing and weather-resistive barriers through window and door framing packages and exterior finishes — as a single, integrated scope.
Disconnected envelope trades create gaps. Gaps create build errors. NBS eliminates the gaps by managing every component of the exterior envelope under one contract with one accountable delivery partner.
- Wall assembly design and materials specification
- Structural sheathing and weather-resistive barrier (WRB) systems
- Window and door rough opening packages
