Most popular
Signature Series
The everyday window for Ontario renovations and new builds. Classic proportions, durable hardware, and a price that stays sensible.
Aluminum
Lumina Series
Thermal-break aluminum with slimmer sightlines and a stronger frame. Built for larger openings and a sharper, contemporary line.
Glass technology
Premium low-E glass.
Four coatings. Pick the one that matches the room’s orientation — winter heat, summer shade, or a bit of both.
01
LoĒ-180
High solar gain. The right coating for north-facing glass — it lets winter sun in and cuts UV.
02
LoĒ²-272
The year-round standard. Balanced solar control and insulation for most elevations.
03
LoĒ³-366
A triple-silver coating that rejects the most summer heat while staying clear.
04
LoĒ-i89
A fourth-surface coating for the coldest exposures, when you want one more layer of insulation.
Customization
Endless colour
designs & sizes.
Match the house. White, black, and the shades between — plus two-tone frames and sizes built to the opening.
Crafted with precision

Performance year-round
Built for every season.
Canadian weather doesn’t take a day off. The glass and the frame are specified for that.

The Lorvano advantage
Built for
homeowners.
One company from the measurement to the install. The quote, the glass, and the crew all answer to the same name.
Factory-direct pricing
You buy closer to the build. No extra showroom stacked on top of the price.
Custom built to order
Size, style, colour, and glass specified for the opening. Nothing forced into a stock size.
20-year warranty
Glass, frame, hardware, and seals — written down, not implied on install day.
Fast turnaround
Standard orders are scheduled in weeks, so the rest of the renovation can stay on the calendar.
Built for our winters
Frames and glass chosen for Ontario cold and summer heat, not a milder market.
