Creating a space that stays comfortable in every season isn’t a luxury—it’s a necessity.
Especially when you’re surrounded by the breathtaking highs and lows of a place like Montana. That’s exactly why we designed our thermally broken steel windows and doors to perform just as beautifully as they look.
You can see it in the image above: wide open views, clean lines, and rock-solid steel framing a living room that’s as inviting in January as it is in July.
This is our 6500SB Series in action—fully welded, cold-rolled, and made right here in the USA. Every unit is packed with smart features like dual weather-stripping, energy-efficient glazing up to 1 5/8”, and an internal thermal break that keeps the cold out without sacrificing style.
Montana Views, Zero Compromise
We know what our clients in the Rockies (and everywhere else) are dealing with—big swings in temperature, dry air, snow, and sun.
That’s why our thermo-insulating profiles are designed to handle extremes with ease.
You get:
| Feature | Benefit |
|---|---|
| Thermal Break | Insulation from outdoor temps |
| Fully Welded Frames | Long-term structural integrity |
| Dual Weather-Stripping | Keeps drafts and moisture out |
| Glazing Options Up to 1 5/8” | Flexibility for performance glass |
| Oversized Openings | Bigger views, uninterrupted light |
| Custom Configurations | Tailored to your space, not the other way around |
This project showcases one of our favorite benefits: blurring the line between inside and outside. Whether you’ve got a blizzard or a heatwave rolling through, you stay cozy while soaking up the view.
Built for Harsh Climates, Designed for Life
Montana doesn’t go easy on materials—and we don’t either. Our thermally broken steel windows and doors are built with galvanized steel, protected by a zinc-rich epoxy primer, and finished with a super durable polyester powder coat that meets AAMA 2604 standards.
They’re engineered to resist:
- Warping
- Condensation
- Rust
- Energy loss
- Fading
We don’t just meet industry benchmarks—we exceed them.
Why Thermally Broken Steel Changes Everything
Traditional steel windows are known for beauty but not always comfort. With our thermally broken systems, you don’t have to choose.
We bridge the gap between performance and aesthetics—literally—with a high-performance insulating barrier embedded in the frame.
That barrier creates a thermal break, which means:
- No icy frames in winter
- No heat radiating inside in summer
- Lower energy bills all year round
Think of it like wearing a down jacket with a windbreaker shell—style and function, locked in together.
The Flexibility to Fit Any Home
Whether you’re building new or renovating, our systems can flex to fit.
We offer configurations for:
| Type | Dimensions |
|---|---|
| Casement Windows | Min 18”x18” – Max 42”x90” |
| Projected Windows | Min 14”x14” – Max 66”x48” |
| Single Doors | Min 24”x72” – Max 48”x120” |
| French/Double Doors | Min 48”x72” – Max 96”x120” |
Need something beyond these specs? No problem. Our team works directly with architects and builders to engineer oversized or non-standard solutions. We’ve pushed the limits before—and we’ll do it again.
Design Meets Durability
We’re known for minimal sightlines and timeless industrial beauty, but none of that matters without lasting quality.
Every unit is finished in-house to maintain control over fit, color, and coating quality.
We’re proud to back our powder coat with a 10-year warranty.
And color? You’re not stuck with black. We offer custom color matches (even non-metallic options), so your windows reflect your style.
We believe that steel should work as hard as it looks good. And nothing proves that more than a Montana living room like this—open to the world, yet fully protected from it.
Optimum Window thermally broken steel helps make every room feel like the best seat in the house, no matter what’s going on outside.
