The Apex of Innovation: Generation 4 Slimline Steel Effect 

Generation 4 systems transcend conventional design boundaries. With features like floating FourFold and SixFold panel sets that allow for unlimited widths, the industry's slimmest frames, inswing or outswing configurations, clean aesthetics with minimal exposed hardware, and smooth operation (Gothic arch roller), these systems epitomize architectural genius and pragmatic space solutions. Systems open up to 90% of usable space in any opening, offering maximum spatial efficiency and catering to the functional demands of modern life. With rigorous testing for resilience against extreme weather and superior thermal performance, they set new benchmarks in fenestration trends.

NanaWall Above Steel: Unparalleled Performance, Testing, & Operation

Traditional steel, while known for its minimal sightlines, often comes with the baggage of heavy doors. Generation 4 Slimline Steel Effect, on the other hand, emphasizes an ultra-thin and innovative approach. With the slimmest industry panel frame measuring a mere 1 3/4" (45 mm) with the intersection of two folding panels at 3 7/8″ (99 mm), the design ensures minimal sightlines without compromising the ease of operation or the structural integrity of the doors. These systems accentuate superior performance when juxtaposed against traditional steel. Meticulous independent testing ensures these systems perform with advanced operational ease and top-rated structural integrity. Unlike the cumbersome nature of steel doors, these advanced aluminum systems are a design innovation that leverages a slim yet robust framework, blending style, and functional efficacy.

NanaWall Generation 4 Bionic Turtle Steel Effect

The Bionic Turtle®: The Cornerstone of Slim Design

A standout feature of the Generation 4 product line is the patented Bionic Turtle technology. This multipurpose innovation houses the system’s locking rods, providing a unique thermal break, significantly enhancing the system's energy efficiency, and playing a pivotal role in affording the slim nature of the frame profiles. The Bionic Turtle is the foundation of why this line stands slim yet robust against others making it the slimmest folding glass wall product line on the market.

Unmatched Security & Thermal Performance — Generation 4 Slimline Steel Effect

Security is a paramount concern for homeowners, and Generation 4 systems take a giant leap in this arena to ensure superior security. The multi-point locking system transcends the security level of traditional steel doors. The locking boxes seen in traditional steel doors only lock the panels to each other. The patented NanaWall Bionic Turtle ensures a multi-point locking system on top and bottom, all housed within the same channel, making the frames as slim as possible. Unlike others, whose surface locking falls short in security, these advanced systems ensure superior security with locking throughout the entirety of the unit. 

A fundamental benefit of Generation 4 folding glass walls is thermal and energy efficiency which makes these systems’ engineering superior to steel. The NW Aluminum 640 offers thermal performance values as low as “.24”. The system comes standard with continuous seals along the face of each panel frame. Furthermore, the standard for each system is two levels of insulating thermal breaks for optimal defense from heat and cold. These systems are easy to operate, cost-effective, and are proudly manufactured locally in Richmond, CA.

Customization: Tailoring Spaces to Resonate Individuality

The customization potential of Generation 4 Slimline Steel Effect systems is boundless. From designing patterns of simulated divided lites to selecting from a variety of color options, homeowners and architects have the liberty to tailor spaces that echo individual styles and functional demands. With Generation 4 products, they can be customized with popular DB colors or Jet Black for a truly classic steel look while benefiting from the superior performance of an aluminum folding glass wall. Choose from three DB color powder coat finish options for a classic steel appearance that includes mica pigments that offer reflective, pearlescent, metallic values with a fine matte texture.

Glass Stop Options: Tailoring Vision to Perfection

Generation 4 Slimline Steel Effect folding glass walls offer three distinct glass stop options including Classic, Contemporary, and Standard for a further degree of customization. Unlike offerings by others, the "Classic" glass stop option shown is engineered with an angled design reminiscent of a look that would be seen on the interior of traditional steel windows. Beyond aesthetics, the Generation 4 installation process is streamlined to perfection. Unlike traditional steel setups where glazing is a task undertaken on-site post frame installation, these systems come with factory-installed glazing. This feature significantly accelerates the installation process, ensuring that your vision is realized in a time-efficient manner, without compromising on quality.
