borne debris would not penetrate the enclosure and its structural elements. Therefore, this test is not
required for the panels used as a guardrail system.
Summary
Based on our understanding of the NCBC requirements, our conclusions follow:
1. Each panel is constructed of fully tempered, laminated glass.
2. Each panel is secured to the structure with three supports.
3. A top rail is not required for these panels.
4. Wind pressure – previous testing confirms that the panels meet the 180 mph factored wind
speed requirement, with a calculated factor-of-safety of 2.24.
5. The panels do not require wind debris projectile testing.
Please call or e-mail us to discuss this analysis or any portion of the project to evaluate your panels.
