Faux Muntins & Mullions

In these instances it is essential to locate an alternative window that is in line with the style and size of the present one.
Installing a grid window is a less expensive option. These windows are made of a complete glass pane that has a series of muntins, which are glued to the surface. This creates a split appearance. These windows are not as energy efficient as traditional windows.

It is important to remove the strip that separates the sash from the other to allow access to the location where the sash cords are.
It's important that you check the metal tabs on the old sash to those of the new one.
