Features & Options

Each of our products offers specific design options, to suit a variety of applications.

These standards represent the quality and product features for all Cascadia windows and doors. Each product is then custom manufactured to project-specific design criteria: upgrades are available for even higher performance. 


Glazing Units: Except for outswing units, IGUs are generally installed / replaced from the interior side.

  • Standard IGU: Cardinal LoE²-270® All Climate Solar Control double glazed, argon filled; U value 0.25 (R4), SHGC 0.37 for IGU only - more efficient glazing units also available

  • Sound Transmission Class: STC ratings are project-specific (typical values range from mid 30’s to low 40’s)

  • Low conductivity stainless steel edge spacer

  • Dual edge seal (PIB and Silicone)

  • We offer a variety of obscured glass. Please see attached pdf (below) for images and technical info.


Finish: Hydro-Tuff waterborne urethane coating (available in many standard colours, and virtually any custom colour).

Joint Construction: Joints are miter cut and fastened together with shear blocks. All fasteners are stainless steel.

Installation: Several installation methods can be utilized. Our preferred method is a clip anchor for sides and top with a back dam angle at the sill: this allows for units to be installed from the interior or exterior. Traditional nail flange attachment is an option with all window and door series.

Options: Grilles; simulated divided lites; trickle vents (to meet Seattle ventilation requirements). Insect screens are optional for all operable units.
