Window styles
Start with how the window should open and perform.
Operating style affects ventilation, cleaning, egress and sightlines. Fixed units prioritize daylight and efficiency, while projection windows change both the interior and exterior opening.

Operating, fixed and performance choices
The best style is the one that fits the opening and the room.
A window should be selected around ventilation, reach, furniture placement, exterior access, egress requirements and the desired amount of glass—not by appearance alone.
Glazing package
Compare insulated-glass construction, pane count, coatings, spacers and gas fill as a complete package.
Frame and configuration
Frame material, sightline, mullions, exterior profile and combination layout affect both performance and appearance.
Comfort and performance
Orientation, solar exposure, air sealing and condensation resistance should be considered for the actual room.
Operation and egress
Opening size, operating direction, hardware reach and applicable egress needs must be checked at the opening.
Frame, configuration and installation
Specify the whole replacement, not only the sash style.
The final quotation should connect the selected window to the existing frame, wall, trim and finish conditions.
Frame configuration
Confirm overall unit size, frame depth, mullions and exterior profile.
- Single or combined units
- Interior and exterior finish
- Drainage and sill conditions
Glass and hardware
Review the glazing package and operating components together.
- Double- or triple-pane options
- Low-emissivity coatings
- Locks, operators and screens
Installation method
Choose the replacement approach after the existing opening is assessed.
- Existing-frame condition
- Full-frame or insert scope
- Air, water and finish detailing
Measurement and installation
Measurement determines the installation method.
We assess the existing window, surrounding finishes and access before confirming the product dimensions and written installed scope.
- 01
Assess the opening
Review frame condition, water management, exterior cladding and interior trim.
