The 2F-0000 is the window and door muntin system and other accessories. Muntins are small bars that divide the large glass panel within a single sash or fixed frame. They aren’t for everyone, but if you are appealing to a traditional appearance, 2Fold® has a number of standard shaped available to choose from. Of course, custom shapes and sizes are also available on special order.
The 2Fold™ muntin is a 3-part, simulated divided lite (SDL) system. The exterior is steel and fully welded or laser cut into the exterior sash frame. Within the insulated glass unit is a spacer bar that matches the black appearance of the IG perimeter spacer and makes it impossible to tell the difference between this SDL and a true divided lite. The interior Accoya® piece is lap jointed at intersections and connected at the perimeter to the glazing frame.
If you are a muntin lover, this is the best you can get without jeopardizing the structural integrity and rigidity of the sash.
