How it works:
Only the sash of the old window (the part that holds the glass) is removed. The new window slides neatly into the existing frame.
- Less installation time and labor—installation can typically be completed in about an hour per window
- Installation uses Pella’s exclusive SmartFlash® installation tape and Great StuffTM 1 Pro Window and Door Insulating Foam Sealant
- Includes a full perimeter sealant, such as OSI® QUAD®, to help keep out air and water
- Less glass area
- Uses the existing window frame
