Slim aluminum frames for big glass

Aluminum is the strongest, most commercial-grade frame we work with, and that strength buys something no other frame can: very narrow sightlines and very large glass. Where a vinyl frame would need to be chunky to carry a big pane, a slim aluminum profile carries it with a thin border — more glass, more light, a clean modern look.

The old knock on aluminum in a cold climate was that metal conducts cold straight through, so we install only thermally-broken aluminum, where an insulating barrier is built into the frame to stop that cold transfer and the condensation that came with it.

It is a natural pick for picture windows, contemporary builds and big feature glass. Where a warmer frame is the smarter call, we will point you to vinyl windows, fiberglass windows or clad wood windows instead — honestly.

How it works

Four steps from free measure to sealed install

  1. Book the estimate

    Call, text or use the form. We book a free in-home visit — no obligation, no high-pressure sales table.

  2. On-site measure

    We measure every opening, check the frames and sills for rot or water damage, and walk through material, style and glass options in plain language.

  3. Written quote

    Line-item quote with the window line, glass package, U-factor, warranty and haul-away on one page. Financing attached when you want it.

  4. Install, cleanly

    Drop cloths, boot covers and a full air-seal on every unit. Old windows hauled away and a walkthrough of your new windows plus warranty registration.

What you get

Modern glass, thermally-broken and sealed

Every thermally-broken aluminum unit is measured on site and installed by our own crews with a full perimeter air-seal, so the insulating break in the frame is matched by a tight seal in the wall — together they prevent cold transfer and condensation in Montreal winters. It is the same care we bring to every window we install.

The glass package and U-factor are confirmed in the written quote before anything is ordered, and the job carries a written warranty. On big modern panes we spec triple-pane Low-E to keep all that glass warm. Ready to start? Book a free estimate, explore commercial storefront windows, or read the common questions.

Common questions

Montreal aluminum window installation, answered

Cold transfer, the modern look and durability of aluminum frames.

Only non-insulated aluminum is — the bare metal frames from decades ago conducted cold straight indoors and sweated with condensation. We do not install those. Every aluminum window we fit is thermally broken, meaning a low-conductivity barrier is built into the frame to separate the cold outer face from the warm inner face. Paired with triple-pane Low-E glass and a proper air-seal, a modern thermally-broken aluminum window performs well here — you get the slim, modern look without the cold-frame drawbacks of the old stuff.
For slim sightlines, maximum glass area and a clean, modern architectural look that no other frame can quite match. Aluminum's strength lets the frame be thin while still carrying large or tall panes, so more of the opening is glass and the borders almost disappear — ideal for contemporary homes, big feature windows and expanses of fixed glass. It is also extremely durable and stable. Where the design calls for minimal frame and maximum view, aluminum is the material that delivers it.
Very — aluminum resists warping, corrosion and the swelling and shrinking that temperature and humidity cause in other materials, so a quality unit holds its shape and operation for decades. It will not rot, will not rust in our climate, and the finish is baked on to resist fading. The one thing that matters is the thermal break and the seal, which is why we install thermally-broken units and detail the perimeter carefully. Done right, an aluminum window is one of the longest-lasting frames you can buy.
On contemporary homes and large feature glass where you want slim sightlines and maximum glass — always thermally broken so it performs in our climate.
Yes — aluminum takes a durable factory finish in a wide range of colours inside and out, which holds up well against sun and cold.

Wanted a modern look with minimal frame and the thermally-broken aluminum delivered — slim, sharp and no cold transfer.

Big contemporary glass with almost no visible frame. They were clear that it had to be thermally broken for our winters, and it is warm.

R. Grewal
Homeowner, Laval

Sleek aluminum frames on the front of our mid-century house. Durable and dead-on for the architecture.

Clean lines, maximum glass and a solid, precise install. Exactly the modern look we were after.
