The Tyz-All 50x80 plastic window kit reduces the amount of energy loss experienced through windows. This window insulator comes with a piece of insulation film, a channel system, and plastic spline. Installation is simple, and can be completed in a few steps:
- Plastic channels should be attached around the window frame.
- Spread the insulation film over the face of the window.
- Use the spline (thin plastic strip) to hold the film in place, and lock it into the channel.
- If necessary, trim the spline and channels with a utility knife, and the insulation film with scissors.
