A narrow-frame profile that turns to reveal a full-height column of aluminum is a compromise. A wall that opens with effort — or with a stubborn track — is a compromise in another direction. Alta Vetro sliding lines refuse both. Lift & slide systems raise the panel off the seals for effortless movement, then seat it back down for full compression at rest. Multi-track and pocket configurations open a full wall away. Narrow-frame panoramic systems reduce visible aluminum to the barest minimum, so the view carries the room. ### Engineered for Large, Heavy Glass The engineering the movement conceals is real: insulated glass units with low-E coatings, argon-gas fill for thermal performance, and edge seals that hold at altitude. Frames are thermally broken to stop bridging and internal condensation. The hardware is designed for large, heavy glass panels over decades of daily use. Flush barrier-free tracks and integrated threshold drainage let the indoor-outdoor transition sit level, and retractable screen solutions preserve sightlines on large openings. On CW-PG55-rated projects, our bi-fold and specialty lines pick up where sliding leaves off; on ADA and level-transition builds, the barrier-free thresholds carry through. ### Mountain-Climate Ready The Colorado climate is unforgiving on expansive glazing. Our lines are NFRC certified, thermally broken, and engineered for wind, water, and snow load. When code demands stringent U-factor and SHGC on large glass area, our specification support helps balance the design with the performance the building envelope needs. What's Included ## Configured to Your Project - 01 Lift & slide systems for panoramic openings with effortless operation - 02 Multi-track sliding configurations for full-wall openings - 03 Narrow-frame panoramic systems with minimal visible aluminum - 04 Engineered for large, heavy glass panels with smooth, stable, quiet operation - 05 Flush barrier-free tracks, integrated drainage, retractable screens Why Alta Vetro ## The Difference in Every Detail Panoramic Sightlines Narrow-frame profiles reduce visible aluminum so the view — not the frame — carries the room. Effortless Operation Lift & slide hardware moves oversized panels smoothly, quietly, and reliably for decades. Barrier-Free Living Flush sills and integrated drainage support level indoor-outdoor transitions. Engineered for Colorado Thermally broken frames, low-E insulated glass, and NFRC certification balance glass area with performance. The Process ## From Consultation to Certified Install 01 ### Design Consultation We review the opening, orientation, and view lines with you or your architect. 02 ### Configuration Track type, panel arrangement, glass, finish, and threshold are configured to the project. 03 ### Specification & Order Structural and thermal data are delivered for the specification package. 04 ### Certified Installation Installation is coordinated through The Install Company for warranty confidence.

Specifying Alta Vetro gave our clients the wall they wanted with the thermal performance the code demanded.” Architect, Mountain-Modern Studio Aspen & Snowmass > “The pivot door is the moment guests remember before they even step inside. Oversized, effortless to operate, and finished exactly to our palette.” Custom-Home Client Cherry Hills Village > “Alta Vetro delivered the same class of thermally broken, large-format glass at a price that actually fit the project. Accessible luxury is the right description.” General Contractor Vail & Beaver Creek FAQ ## Sliding Systems — Common Questions ### How wide can a sliding-glass wall open? Multi-track and pocket configurations can open a full wall. Panel sizes and opening widths are configured per project to the architecture and structural context. ### Can I have a barrier-free threshold? Yes. Flush barrier-free tracks with integrated drainage support level indoor-outdoor transitions, and drainage is configured for snowmelt where the opening is exposed. ### How is the panel weight handled? Lift & slide hardware raises the panel off the seals for effortless movement, then seats it back down for full compression at rest. It is engineered for large, heavy glass over long service life. ### Are the systems NFRC certified? Yes. Our sliding lines are NFRC certified, and we support architects with the certification framing needed for energy-code compliance without publishing raw test tables. ### Can I integrate a retractable screen? Yes. Retractable screen solutions are available across the sliding line and are coordinated at specification time. ### Do sliding walls perform in Colorado's climate? Yes. Thermally broken framing, low-E insulated glass units, and durable weather seals let the systems meet IECC energy code and hold up through freeze-thaw cycling.
