The NW Aluminum 643 provides the visual appeal of classic steel-framed doors while delivering the performance of an aluminum folding glass wall.
NanaWall, a market leader in opening glass wall technology, is thrilled to introduce the NW Aluminum 643, a revolutionary folding door solution that blends a steel impression with a durable, high-performance aluminum structure. The system, which is part of NanaWall’s Generation 4 product line, has undergone updates to improve performance, security, and design consistency.
The NW Aluminum 643 provides the visual appeal of classic steel-framed doors while delivering the performance of an aluminum folding glass wall. The choice for unique steel-effect coatings and simulated divided-lite patterns gives designers visual versatility, while NanaWall’s Gothic arch roller design ensures quiet, frictionless, seamless opening and shutting. The system provides a low-cost approach to obtain a steel-like appearance while delivering 1.5 to 2 times greater thermal efficiency, making it a high-performance option for both residential and commercial applications.
Benefits include:
- Weather-Rated, Low Profile Saddle Barefoot-Friendly Sills: The system has Florida Product Approval for inswing, outswing, and open-corner configurations, and it includes both an ADA-compliant and barefoot-friendly Low Profile Sill. A Performance Sill is offered for more demanding coastal and extreme weather conditions.
- Thermal Efficiency: Double and triple glazing choices provide low U-values (as low as 0.24), decreasing heat and cold transfer.
- Superior Security: The system incorporates tamper-resistant locking bolts with a 1″ throw into the head track and sill, resulting in a more robust locking mechanism. The system can also be linked to third-party home security systems to increase security.
- Customization: In addition to the ability to be tailored with simulated divided-lite patterns and steel-effect finishes (SE Black, SE Classic Bronze, SE 702, and SE 703), this system is unique in that it has extremely slim profiles that rival thermally broken steel products, as well as specialized contemporary glass stops that deliver an ultra-slim and refined appearance. The technology provides floating FourFold and SixFold panel sets with limitless lengths.
