ZapPack replacement wood window

Caradco's ZapPack replacement wood window is designed to be easier to install and less expensive than most vinyl replacement window systems. ZapPack replaces only the jamb liners and old sash, the most common sources of leaks and drafts. Because the original window frame, plaster and woodwork are not disturbed, ZapPack can be installed in a relatively short time. The energy-efficient double-hung sash are crafted of solid western pine and run in smooth, precision- manufactured vinyl tracks.
