Highly decorated for a demanding military project.
Polyfoam Roof System
HANGAR AT NAS NORTH ISLAND
These historic helicopter hangars are well-known and symbolic throughout the military, adding an extra level of pressure to our project. The arched roof, odd angles and shapes that give these hangars their unique character also made application difficult. Adding to the challenge were leaks in the existing substrate, the black color requirement and seagull intrusion. We worked with a supplier to specify a custom formulation, and were challenged to eliminate the risk of overspray which would have threatened billions of dollars worth of nearby aircraft.
- Removed existing EDPM built-up roof
- Applied 1 1/2” 3.5 density poly spray foam Nitrocoat polyurea basecoat
- Applied weather-resistant silicone topcoat
- Combated arched roofs by rapelling down building
For our work on this unique project, Barrier received the National Industry Excellence Award from the Spray Polyurethane Foam Alliance (SPFA) – the only California firm to earn this honor.
