SUITABLE STANDARD WINDOW SIZES

FOR AMERICAN INGENUITY DOMES

 

These tables contain CALL SIZES which are the customary size identification of the window industry.

Call Size is the actual window dimension, for example” Call Size 3/4 x 4/6 expresses 3’-4” x 4’-6”,

which converts into 40” x 54”.

 

H = Horizontal sliding or Horizontal rolling windows      
V = Vertical sliding, either double hung or single hung    
C = Casement, swinging type window        
Sizes listed in Bold are best suitable for egress in bedrooms.

The horizontal dimension is always listed first x vertical dimension.

Cupola windows can not qualify for egress because they are too high above the floor.  

Two Standard Vinyl Horizontal Roller or Slide Type Windows are needed to fill one rough window opening of a cupola.

They can be installed with a Mullion in between them or custom windows can be installed.

 

Florida and most other state’s code for Glass and Glazing requires tempered glass to be used in windows whose

nearest edge is within 24” radius of a door in closed position.  Tempered glass is also required for glass panes

with a bottom edge less than 18” and a bottom edge greater than 36” above the floor.
