Mixing modern and rustic design may sound like walking a tightrope — but this Montana home lands the balance with effortless grace.
Set against a backdrop of snow-capped peaks and endless evergreens, its clean lines and warm textures create a space that feels both elevated and inviting.
At the center of it all? Our RTS-430 Thermally Broken Steel Windows and Doors — the most thermally-efficient series we’ve ever produced.

A View Without Compromise
When you live in a place where the views are as dramatic as the weather, you need windows that do both:
Frame the scenery like a work of art, and stand up to the elements without flinching.
Our RTS-430 series offers thin sight lines for uninterrupted vistas, while the thermal break technology locks in warmth and keeps the mountain chill exactly where it belongs — outside.
The triple-glazed, NFRC-certified design provides U-values as low as .19, rivaling high-performance wood windows for energy efficiency.
It’s comfort without compromise, beauty with backbone.
Designed for Montana Winters
This isn’t just about keeping a home warm — it’s about keeping it cozy.
Our compression gasket system and precision welding mean air and water stay out, no matter how hard the wind blows.
From the first frost to the last spring melt, these windows stand their ground.
Inside, homeowners enjoy expansive glass panels that welcome in daylight and connect every room to the landscape beyond.
Built for Collaboration
This home wasn’t built in isolation — it was the product of an incredible team of architects, builders, and designers who knew that details make the difference.
Every RTS-430 unit was custom-fabricated to exact specifications, ensuring the fit, finish, and performance met the highest standards.
We worked closely with the design team to keep the modern steel profiles light and airy, allowing the rustic elements — natural wood beams, stonework, and textured finishes — to shine alongside them.
