1. Door Frames
Primed and Vinyl Clad frames,
complete with weather stripping
and exterior trim, make your door
an energy efcient prehung unit.
2. Weather stripping
Compression weather stripping
on the hinge side and magnetic
weather stripping on the lock side
seals out the heat and cold. Your
door seals like a refrigerator.

Energy efcient door lites come
standard with safety tempered
insulated glass. Lite frames are
made with a heat and UV resistant

storm door.
