How We Matched Equivalent Systems
Euro-Wall's Claim: Euro-Wall positions itself as a “NanaWall alternative,” but its content mixes two different types of systems: thermally broken folding doors and impact-rated non-thermally broken folding doors.
NanaWall's Response: To keep the comparison honest and valuable, we have separated the two categories below. First, you will see a data-driven comparison of our thermally broken glass wall system, NW Aluminum 640, versus Euro-Wall’s thermally broken offering. Next, we compare our thermally broken, impact-rated SL73 to Euro-Wall’s thermally broken, impact-rated system.

Both products are certified for HVHZ use and tested to TAS and ASTM impact protocols. NanaWall publishes full test results for air, water, structural, impact, and cycle performance. NanaWall offers more water-rated, inswing and outswing sills, including an ADA-compliant option. Euro-Wall offers taller maximum panel heights and standard Kynar finish options, yet very limited testing results.
For projects requiring verified structural performance, detailed water and air data, and long-term durability testing, NanaWall SL73 impact-rated folding glass door provides certified results and transparent test reporting. Download Design and Technical Resources
What Euro-Wall Gets Right
- Taller panels available (up to 14 ft)
- Kynar finish is standard on many models
- Florida Product Approval and HVHZ certification
These are valid distinctions. When panel height or finish selection is the primary requirement, Euro-Wall may be a suitable option.
Where NanaWall Leads
- Performance results from certified labs for BOTH Inswing and Outswing units
- NFRC-certified, validated, and labeled products
- Mechanical durability and cycle testing at verified counts
- Independent acoustic testing on applicable systems
- EPD (Environmental Product Declaration) and HPD (Health Product Declaration) certifications available
- Better security with glass stops located on the interior of panels
NanaWall matches or exceeds Euro-Wall in other areas. For applications that require documented performance for structural loads, water penetration, air infiltration, acoustics, and long-term durability, NanaWall provides complete system performance in the published architectural binders.
NanaWall vs Euro-Wall: Comparison FAQs
The following questions address common comparisons, code approvals, and performance considerations when evaluating NanaWall and Euro-Wall glass wall systems.
- Euro-Wall offers some comparable folding and sliding glass wall systems, particularly in configurations where taller panel heights or standard Kynar finishes are the primary requirement. However, a meaningful comparison requires matching equivalent system categories, such as thermally broken to thermally broken and impact-rated to impact-rated.
- NanaWall publishes complete third-party tested performance data across structural load, air infiltration, water penetration, and thermal performance categories, allowing architects and builders to evaluate systems based on verified results rather than general specifications.
Yes. NanaWall offers impact-rated folding glass wall systems with Florida Product Approval, including configurations suitable for High Velocity Hurricane Zone (HVHZ) applications. Documentation is publicly available and includes published third-party test results.
NanaWall systems are also NFRC-certified for thermal performance, providing verified U-values and performance ratings for specification.
View SL73 Architectural BinderNanaWall publishes tested design pressure ratings up to +80 / –110 psf for certain SL73 thermally broken impact-rated configurations. Euro-Wall’s publicly available design pressure listings are typically around ±50 psf, depending on configuration.
Performance ratings should always be reviewed alongside sill type, panel size, and ADA compliance to ensure accurate system comparisons.

Performance Value Over Time
NanaWall Verified Fact: NanaWall systems are supported by documented testing demonstrating strong structural performance, air infiltration control, and acoustic performance. This testing supports long-term reliability and lifecycle value beyond initial purchase cost, ensuring architects and builders specify with confidence.
Euro-Wall Claim: “Euro-Wall offers the same performance at a lower cost.”
NanaWall Products are NFRC-certified
Manufacturing Origin Transparency
NanaWall Verified Fact: NanaWall’s primary aluminum folding glass wall systems are manufactured in California, while its wood systems are produced in Germany. This dual manufacturing approach supports system-specific engineering, material expertise, and long-term quality control.
Euro-Wall Claim: “Euro-Wall builds all panels in the USA; NanaWall only some.”
NanaWall Sustainable Design and Material TransparencyThe Real Story on Price
Euro-Wall highlights affordability on certain lines. NanaWall focuses on lifecycle value and verified performance. A lower initial price does not always translate to lower long-term cost. When energy savings, long-term durability, fewer service calls, and proven structural and weather performance matter, NanaWall provides greater value.
For a fair cost comparison, specifications must match: same panel size, same hardware, same glass package, and the same installation conditions.

We put the NanaWalls in mainly to embrace the the waterway and embrace the outdoors.
I'm now at the point where we've survived hurricane Matthew and the NanaWalls, did a very good job, so we're looking at we're replacing all the other windows that weren't hurricane proof with NanaWall systems or NanaWall windows.
— Christi & David Llewellyn, NanaWall Owners
There's a rhythm to how you live here. Mornings that start on the fairway, afternoons with the doors wide open, the natural light and the breeze flowing right in. The NanaWall system doesn't just frame the view, it shapes how you experience it.
— Jerud Martin, Builder
“We use our NanaWall system daily for vehicle access, so security and weather protection were critical. We chose the SL73 because it locks securely and performs reliably in storm rain and high winds. These are capabilities we could not achieve with sliding doors.”
— Richard A. Rubio, Manhattan Motorcars Hamptons, Business Owner
