Rough-Opening Window Install
“Rough-Opening” Window Installation Procedures
The following procedures are included with a WinDura “Rough-Opening” window installation. This is an optional method of installation, and is intended to yield the following benefits:
- Maximum insulation ability around the new window frames
- The ability to build the new windows as large as possible for maximum glass space
- Restoring the window design to match the original (The alternative “Pocket” installation of replacement windows can result in reduced glass-space and a modified look)
- Removal of all existing exterior wood trim
- Removal of existing window frame and sashes
- Interior trim (casing) is retained and will be reused (unless damaged, or new trim is desired)
- Stud, or “Rough”-opening is inspected for water damage and other problems
- New window installed, squared-up, shimmed, and fastened to rough-opening. In most cases, the windows will come with an applied nail-fin accessory for a positive water-shield around the opening
- Matching interior jamb-extensions installed
- Insulation fully packed into the cavity between the window frame and studs
- Full vinyl exterior trim installed and sealed to the window frame and the siding
- Finish caulking is performed to the interior and exterior window and trim edges

Why this is important …
Many replacement window companies perform the easier “pocket” installations, in which the existing frame is left in place. This results in the following potential problems:
- Aesthetic issue—reduced/narrower glass-space
- Aesthetic issue—new interior trim stops installed around the perimeter—will change the appearance vs. original, and/or other windows not replaced
- Inability to add insulation around the outside of the window frame—(the cavity is not revealed if the outside trim is not removed)
- Inability to inspect or repair the condition of the “rough opening”—if rot, mold, or damp insulation exists—will not be revealed and corrected
