Our Window Lineup

Casement window replacement — ENERGY STAR triple pane
Best Seller ER Rating up to 41 ENERGY STAR Most Efficient

Casement Windows

The most energy-efficient window style available. When closed, the sash presses tightly against the frame creating a compression seal that virtually eliminates air leakage — the gold standard for Canadian climates.

Why Casement?

Tightest Seal of Any Style

Sash compresses against the frame under wind pressure — unlike sliders that rely on weatherstripping alone.

Triple Pane LoE-180 Glass

Two Low-E coatings with 97% argon gas fill. ER rating up to 41 — compared to ER 28 for standard double pane.

Super Spacer® Foam — No Condensation

100% polymer foam spacer blocks heat conduction at the glass edge, eliminating cold edge condensation.

Steel-Reinforced uPVC Frame

Galvanized steel inserts inside the vinyl profile prevent warping and allow larger window sizes without deflection.

Multi-Point Locking Hardware

Locks at multiple points around the sash perimeter for security and a consistent airtight seal when closed.

Custom Sizes & Colours

Available in 4½" deep frame (FlexScreen compatible) or slim 3¼" profile. Interior and exterior colour options.

Under the Glass

What's Inside Every
Northline Window

Every window we install uses the same advanced glass and frame technology — built for Canadian extremes from -30°C winters to +35°C summers.

Triple Pane LoE-180 Glass

Three glass panes with dual Low-E coatings achieve an ER rating of up to 41 — 35% better than a standard double pane with one LoE coat (ER 28). Block UV, reduce heat loss, and cut condensation.

ER 34–41 vs. ER 28 (standard)

Super Spacer® Foam

Unlike metal spacers that act as cold bridges at the glass edge, our 100% polymer foam Super Spacer® completely blocks heat conduction — eliminating condensation at the perimeter where it typically forms first.

Zero cold-edge condensation

97% Argon Gas Fill

Argon gas conducts 50% less heat than air. We fill our units to 97% — above the industry standard 90% — for maximum insulating performance in every climate zone across Canada.

50% less heat transfer than air

ER Rating Comparison

The ER (Energy Rating) is Canada's standard measure of window energy performance. Higher is better. ENERGY STAR Most Efficient requires ER 34+.
