Portage Ave aluminum window installation — measured, sealed, warrantied

Aluminum windows offer slim, strong, modern frames — often used for large spans and contemporary looks. We install thermally-broken aluminum for Portage Ave comfort.

Every opening measured on-site

Full air-seal on every unit

Written frame + sealed-glass warranty

Slim frames, big glass

Aluminum is the strongest frame material we work with, and that strength buys you 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, so you get more glass, more light and a clean, modern, almost frameless look.

The old knock on aluminum in a cold climate was that metal conducts cold straight through — so we only install 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 the architecture calls for minimal frame. We will tell you honestly where aluminum shines and where a warmer vinyl or fiberglass frame is the smarter call.

Install, cleanly

Modern look, proper seal

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 — the two together are what prevent cold transfer and condensation in a Portage Ave winter.

The glass package and U-factor are confirmed in the written quote before anything is ordered, and the job is backed by a written warranty. On big modern panes we spec triple-pane Low-E to keep all that glass warm.

Aluminum Window Installation questions answered

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

Is aluminum cold in Portage Ave winters?

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.

Why choose aluminum?

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.

Is aluminum durable?

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.

Where does aluminum work best?

On contemporary homes and large feature glass where you want slim sightlines and maximum glass — always thermally broken so it performs in our climate.

Can aluminum frames be colour-matched?

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.

D. Laframboise

Homeowner, Portage Ave

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

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

A. Cyr

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