Included in this package are eight (8) window frames that measure a scale 3'x6'. These window frames are the same as those included in our Santa Fe Station (1003). They are set up as double panes. To install, first paint the frames the desired color. To make them more easily seen paint them a contrasting color. For instance, if the windows are to be mounted in white walls paint the frames a dark color such as brown or blue to help them stand out better. Next cut a rectangle in the desired location that measures .225'x.450'. The window can be installed in a vertical position or for a more unique look, horizontally. Finally, run a bead of glue around the outer lip of the frame and press it into the hole cut earlier. It is as simple as that!
