Window Glass Design 2002:

Window Glass Design 2002 performs all the calculations required to design glass according to ASTM E 1300-02. In addition the software performs the calculations ASTM E 1300-98/00.  The PGMC endorses the Window Glass Design 2002 Program as being the best tool available to aid in designing window glass to resist wind and long-term loadings.  Members of the PGMC technical council served in program development and each now uses a copy of the program.


A brief word on ASTM E 1300-02

ASTM E 1300, "Standard Practice for Determining the Load Resistance of Glass in  buildings." gives designers a comprehensive methodology to size windows glass to resist uniform loads.  ASTM E 1300 has a robust foundation in research and theory.  It currently provides the basis for window glass design in the International Building Code.  ASTM E 1300 requires the designer to use 42 basic glass strength charts along with numerous other charts and tables to achieve a window glass design in an iterative manner.  Achieving a suitable window glass design using ASTM E 1300 can require considerable time and effort.


Changes in ASTM E1300-02

  • Glass strength charts are based on a 3-sec load (this matches ASCE7-98/02)

  • New design procedures for 1, 2 and 3 side supported glass

  • Asymmetric laminated glass design procedures

  • Laminated-Laminated insulated glass units

  • 4-side edge support designs for aspect ratios up to 10

  • New laminated glass strength charts

  • Allows the input of all the pertinent information for a window including, window glass construction, edge support,  dimensions, window glass thickness, long- and short-duration loading, window glass type, and more.

  • Performs calculations for the following window glass types and constructions supported on 1, 2, 3 and 4 sides:

    • monolithic glass types

      • annealed

      • heat strengthened

      • fully tempered

    • symmetric and asymmetric laminated glass

      • annealed

      • heat strengthened

      • fully tempered

  • Performs calculations for the following window glass types and constructions supported on  4 sides:

    • insulating glass units

      • monolithic - monolithic (including all glass types)

      • monolithic - laminated (including all glass types)

      • laminated - laminated (including all glass types)

  • Performs calculations for aspect ratios from 1 to 10 for all window glass types and constructions supported on four sides

  • Selects the appropriate values from the charts and tables and performs the computations specified in ASTM E 1300-94/98/00/02/03.

  • Checks the resistance of the window glass to the loads and informs the designer whether the window glass configuration has sufficient load resistance for the specified loads.

  • Provides center of glass deflection under design loading.

  • When the designer uses annealed monolithic window glass, the program provides an approximate probability of breakage for the first occurrence of the design load.

  • The program offers the designer the option of viewing the factors the program selects in performing the ASTM E1300-98/00/02 computations.

  • Updating selected input to modify a proposed design is a simple task, allowing for rapid iterations. 

  • Includes a calculator to convert load magnitude of a specified time duration to the equivalent load magnitude for a different specified time duration

  • Includes a dimensioned sketch of the glass unit


When the designer achieves an optimum window glass design configuration, the program prints a report consistent with the requirements of ASTM E1300-98/00/02 suitable for presentation to a building official. In addition the program prints a details report which includes a dimensioned sketch of the glass unit and the factors used to calculate the load resistance.
