Window, Muntin and Method

Abstract

A non-metal window muntin formed from plastic or wood is described for use in hermetically sealed insulated glass windows. The process for forming the muntin includes machining polystyrene sheets which are painted with a latex pain and baked prior to use between sealed glass of the window.

1 . A decorative window muntin made by a process comprising the steps of: providing a non-metal polymeric planar member; constructing a unitary one-piece muntin having no connecting joints and having at least three ends; and coating the constructed muntin with a heat cured coating, wherein said heat cured coating prevents the escape of remaining volatiles from said constructed muntin upon heating. 
     
     
         2 . The muntin of  claim 1 , wherein the coating step comprises the step of coating the constructed muntin with a latex paint. 
     
     
         3 . The muntin of  claim 1 , wherein the providing step comprises the step of providing a polystyrene member. 
     
     
         4 . The muntin of  claim 1 , wherein the providing step comprises the step of providing a polyurethane member. 
     
     
         5 . A window made by a process comprising the steps of: providing a first pane of glass; providing a second pane of glass; providing a unitary one-piece decorative muntin with no connecting joints, said muntin including at least three ends, said muntin comprising a heat cured coating layer; placing said muntin between said first pane of glass and said second pane of glass; and hermetically sealing the muntin between said first pane of glass and said second pane of glass. 
     
     
         6 . The window of  claim 5 , further comprising the step of: coating the muntin with a latex paint prior to placing said muntin between said first pane of glass and said second pane of glass. 
     
     
         7 . The window of  claim 5 , wherein the polymeric muntin comprises a polystyrene material. 
     
     
         8 . The window of  claim 5 , wherein the polymeric muntin comprises a polyurethane material. 
     
     
         9 . A muntin for use in a window, said muntin being made by a process comprising the steps of:
 providing a unitary one-piece muntin with no connecting joints having at least three ends, said planar member adaptable to conform to the window; and covering the polymeric planar member with a heat cured coating, wherein said heat cured coating prevents the escape of remaining volatiles from said planar member upon heating.   
     
     
         10 . The method of  claim 9 , wherein the covering step comprises the step of covering the polymeric planar member with a latex paint. 
     
     
         11 . The method of  claim 9 , wherein the providing step comprises the step of providing a polystyrene member. 
     
     
         12 . The method of  claim 9 , wherein the providing step comprises the step of providing a polyurethane member. 
     
     
         13 . A window made by a process comprising the steps of: providing a pane of glass; providing a unitary one-piece muntin with no connecting joints, said muntin comprising a heat cured coating layer; placing said muntin adjacent to said pane of glass and said second pane of glass. 
     
     
         14 . The window of  claim 13 , wherein the process further comprises the step of: coating the muntin with a latex paint. 
     
     
         15 . The window of  claim 13 , wherein the polymeric muntin comprises a polystyrene material. 
     
     
         16 . The window of  claim 13 , wherein the polymeric muntin comprises a polyurethane material. 
     
     
         17 . The window of  claim 13 , wherein the step of placing a muntin in a window further comprises the step of fixedly attaching said muntin to said window.
