Hāvn Outdoor Living

The Flathead Valley is one of the most spectacular places to live in North America. Glacier-carved mountains, pristine lakes, and a pace of life that draws people from all over the country. But Montana winters are no joke. Heavy snowfall, bitter cold, and a short warm season mean your outdoor space can feel out of reach for months at a time. A Lumon custom sunroom or glazed patio enclosure lets you stay connected to those incredible views in comfort year-round, whether you’re watching the first snow dust the peaks above Whitefish, taking in Flathead Lake from a Bigfork patio, or entertaining in Kalispell as Glacier National Park glows on the horizon.

Lumon is a global leader in frameless balcony and patio glazing, with solutions installed across four continents. Rooted in Nordic design—where simplicity, functionality, and durability go hand in hand—every product is built to last, with an estimated lifespan of over 30 years when properly maintained.

• Frameless glass design: Clean sightlines that complement any home style
• Year-round usability: Engineered for real weather, not just sunny days
• Sustainable construction: Responsibly sourced materials and long product lifespans
• Tailored to your home: Every system is custom-fit, not off-the-shelf
