A true divided look is provided in an insulated two-pane window assembly through use of a resilient silicone foam internal muntin bar grid which is low in thermal conductivity to limit heat transfer between panes and is high in flexibility to allow for bending when forming curved shapes. The grid is secured by adhesive on one side to one pane of glass, thereby allowing natural expansion and contraction of the glass panes. The resilient muntin bar includes the resilient muntin bar being U- shaped with a base from which legs extend which are compressible and adapted to move laterally in response to pressure from the panes due to changing thermal conditions or bonding of external wooden muntin bars to the panes. Movement of the panes toward each other would be limited by bottoming out against the base of the resilient muntin bar.
