GLAZING: Signature Series windows are available in DG1 (double-glazed, OD = 0.75 in., one argon-filled air space) or TG1/TG2 (triple-glazed, OD = 1.36 in., two argon-filled air spaces). TG1 has a single Low-E coating; TG2 has a double Low-E coating for maximum thermal performance.
ALUMINUM CLADDING: Fully extruded aluminum cladding is available in 11 exterior colours: White, Cashmere, Beige, Clear Anodized, Slate Grey, Sable, Taupe, Hunter Green, Redwood, Brown, and Black. Darker colours include Enhanced Colour Protection (ECP) — a Kynar®-based acrofluor coating that resists fading and chalking.
WOOD INTERIOR: Interiors are select stain-grade, solid Hem-Fir (Pine), precision machined to a smooth finish. Hem-Fir can be stained or painted to match any decorating requirement. Screens available in seven prefinished colours plus stainable wood grain.
FRAME CONSTRUCTION: 1-7/8" thick sash is industry-leading in strength and aesthetics. Reinforced frame corners with molded structural corner keys are injected with silicone to ensure durability and resistance against water and air infiltration. Sash components connected with sealed and mechanically fastened mortise and tenon joints.
CASEMENT OPERATION: The concealed multi-point lock seals the sash at multiple points with a single lever. Maximum sash weight is 50 lbs. Egress hinge available on select sizes. Open fully to clean both glass surfaces from inside.
AWNING OPERATION: Hinged at the top and opens outward from the bottom — can remain open during rain without letting moisture in. Ideal for kitchens, bathrooms, dormers, or wherever clearance is limited. Maximum sash weight is 60 lbs. Awnings do not meet Canadian Egress requirements.
