Built for mid-rise residential buildings, our ratings far surpass the required standards, often achieving Architectural Window quality grades. By delivering our windows with fully approved paperwork, we eliminate headaches. Ensuring that every window and element is up to code is an essential part of what we do.
When it comes to quality balanced by durability balanced by
affordability, materials are quite, well, material. More than the
specifications, designs and processes, the materials used to build
a window will dictate the window’s longevity and user experience.
Steel-reinforced uPVC profiles are ultra-durable with ideal
thermal coefficients. The result is a more affordable, low-maintenance,
high-value product. Achieving the perfect balance
between expectation and excellence
Vistaza products are perfectly suited for mid-rise developments.

Exceeding mid-rise standard requirements in the AAMA/WDMA/CSA 101/I.S.2/A440 testing.
Passes high-rise ASTM test E331 and ASTM E547 at
12.11 psf of pressure, achieving 3 times the required CW penetration resistance.
Passes AAMA test E283 at 6.27psf, achieving 4 times the CW standard.
Our profiles are reinforced with .078″ (2mm) steel, 40% thicker than standard uPVC. Providing extra strength with ASTM E330 design pressure at ±65.16 psf (3120 Pa)

More than windows, our products optimize their environment and are one with the universe. Achieving ratings of the lowest U-Factor (heat transfer rate), lowest SHGC (solar heat gain coefficient), and best OITC (outdoor-indoor transmission class—sound reduction rating),
and with the right options can give you a complete Net Zero similar to Passive House ratings.
Rating / Glaze | ThinE | MidE | MasterE | MaxE |
| IGU (Total width) | 15/16″ | 1.25″ | 1.5″ | 2 3/32″ |
| U – Factor (Heat transfer rate) | .26 | .27 | .27 | .21 |
| SHGC (Solar heat gain coefficient) | .39 | .38 | .34 | .33 |
| OITC / STC (Sound reduction) | 25 / 32 | 32 / 38 | 37 / 45 | 40 / 46 |
Results are based using our Crystal annealed glass, upgrading to GrayT or BronzeAge glass may result in even higher energy efficiency.
