Window sash, glazing insert, and method for manufacturing windows therefrom

Abstract

A window sash frame has a glazing insert receiving channel. A glazing insert provides a spacing structure for at least two glazing panes. The spacing structure has at least two glazing surfaces adapted to protrude into a viewing opening of the sash frame and hold a respective one of the glazing panes. The glazing insert includes a base for receipt in the receiving channel of the sash frame. The base extends away from the glazing surfaces such that the glazing panes will be isolated from the sash frame when the base is received in the channel and the glazing panes are mounted on the glazing surfaces.

1 . A method for making windows, comprising: 
 providing a sash frame having a glazing insert receiving channel;    inserting a glazing insert into said receiving channel, said insert (i) having a base for receipt in said receiving channel and (ii) providing a spacing structure for at least two glazing panes,    said spacing structure having at least two glazing surfaces adapted to protrude into a viewing opening of said sash frame; and    mounting said glazing panes to respective ones of said glazing surfaces;    said base extending away from said glazing surfaces such that said glazing panes will be isolated from said sash frame when the base is received in said channel and the glazing panes are mounted on said glazing surfaces.    
   
   
       2 . The method of  claim 1 , wherein each of said glazing surfaces is adapted to hold a respective one of said glazing panes entirely within at least a portion of said viewing opening such that said glazing panes remain outside of said receiving channel.  
   
   
       3 . The method of  claim 1 , comprising using an adhesive sealant to mount said glazing panes to said glazing surfaces.  
   
   
       4 . The method of  claim 1 , wherein said glazing insert comprises a separate leg for each glazing pane.  
   
   
       5 . The method of  claim 1 , comprising providing said base with sides that slope away from said legs.
