With two professional engineers on staff, NCTL can provide various calculations for the fenestration industry.

Anchor calculations:
United Facilities Criteria is used by the Department of Defense as minimum building design criteria can determine anchor quantities/spacing and glazing requirements based on allowable stress and loads.


Structural Calculations:

• ASTM E1300 can be used to analyze a building’s glass load resistance.
• ASTM F2248 is used to determine design loading and blast resistance for laminated glazing.
• AAMA 2502 is used to calculate fundamental design characteristics and wind load resistance.
• United Facilities Criteria can also be used structurally to determine deflection during a blast.

Whether it is site specific ASCE/ SEI 7 calculations or deflection calculations on fenestration components, we can provide an accurate and professional evaluation.
