Combine 60 years of European design excellence with 40 years of American market ingenuity

 As a vinyl extrusion company, our PVC window and door solutions are widely recognized on both continents as the A-list choice for discerning manufacturers, contractors, architects, developers and homeowners.

A bold statement, yes, but REHAU’s uncompromising attention to perfection extends to every stage of the window and door ecosystem, including DESIGN, MATERIAL, EXTRUSION, TESTING, SERVICES and STYLE. While other companies do one or even two stages well, none deliver on ALL OF THEM with the same level of measurable quality and unwavering consistency as REHAU, starting with design.

American ingenuity + German engineering = excellence in performance and style

REHAU became one of the first companies to introduce welded vinyl window systems to North America in 1976, already having become a household name for value engineering throughout Europe. And while many early vinyl window builders sacrificed quality for price in the American market, REHAU never compromised, never stopped pushing design and engineering boundaries.

Superior profiles

The frame and sash at the heart of every REHAU window system boast thicker uPVC walls that make the product sturdier and, in a REHAU breakthrough, appropriate for commercial applications as well as residential.

Many style options

Style, shape, surface and color options provide architects, builders and homeowners with maximum flexibility.

In-house & third-party testing

For structural integrity, thermal performance, acoustical insulation, moisture resistance and ease of operation.

Up to triple glazing 

Glazing channels can accommodate up to three panes of glass for maximum energy efficiency and acoustic performance.  

REHAU’s in-house design team supports custom applications, product enhancements and new product development. Custom design services include modification of existing window and door systems to meet the needs of architects or contractors on specific projects as well as regional differences.

That same sensitivity to market demand also translates into new and enhanced product development. With an ear always to the ground, our designers prototype, test and build the tools necessary to regularly upgrade and expand our window and door product portfolio.

Does the REHAU design advantage sound a little too good to be true?

Raw materials are mixed in-house to ensure durability, energy efficiency and sustainability

Most products are only as good as the material used to make them, which is why the formula for the uPVC (polyvinyl chloride) used in every window and door system at REHAU is a closely held company secret. We mix all raw materials in-house rather than relying on ready-made formulations from outside vendors. The resulting profiles feature qualities not available anywhere else.

Just like the kitchen staff at a fine restaurant, the REHAU “chefs” at our in-house chemistry department are constantly testing and optimizing these formulations to meet the strictest standards.

Example in point #1

We meet and exceed the stringent requirements of the American Architectural Manufacturers Association (AAMA) by adjusting our uPVC formulas for each of the widely varying North American climate zones. REHAU’s window and door systems are part of the AAMA Profile Certification Program, assuring consistent quality that is verified by an independent auditor twice a year. 

Example in point #2

Our latest breakthrough formula, called RAU-FIPRO, combines both PVC and fiberglass for outstanding strength and load capacities without relying on steel reinforcement. Similar to the fiber-composite materials used in aeronautics, RAU-FIPRO addresses the increasing demand for high efficiency window and door products that hold up in commercial applications.

Example in point #3

UV (ultraviolet) light can break down uPVC, causing it to fade and crack over time. We are constantly testing and improving our formulas for UV stability. So, while most extruders are stingy with titanium dioxide to cut costs, we add more of this expensive ingredient because it is critical to keeping the white WHITE in vinyl windows for decades, no matter the conditions.

Extensive weather testing

After extensive weather testing in Arizona (dry climate, high radiation), Florida (humid, hot climate) and Ohio (industrial, moderate climate), REHAU uPVC continuously outperforms standard vinyl with the same like-new color and sheen on day 1,825 (that’s five years) as day one. Given the demand for multiple colors and wood grain/metal-like finishes, we also do extensive comparative testing of our laminate surfacing against other colored, painted, foiled and capstocked (resin coated) windows.

Sooo, can you really afford to compromise on your next window and door project?

Advanced extrusion technology drives precise standards for all our windows and doors

Remember the Play Doh Fun Factory? Load the toy press with Play-Doh, push down on the handle and then watch how the Play Doh squeezes through a mold to create clay strings in wondrous shapes. The extrusion process used to create a vinyl window or door works on the exact same principles as the Play Doh Fun Factory.

uPVC resin is combined with other raw materials (the “dough” in this case) and loaded into a large funnel where it is heated to melting. The molten raw material is extruded through a set of metal blocks called dies. The vinyl “string” (or profile) that emerges is then cut to specific lengths called lineals, which when welded, form a window or door system.

So why should you care about any of this? Because those uPVC profiles are the infrastructure upon which everything else depends when building a superior window or door: structural integrity, advanced thermal and acoustical performance, resilient surfaces, lustrous color and ease of operation.

While the process of extrusion is used by everyone in the industry to produce vinyl window and door profiles, no one does it like REHAU.

Secret uPVC formula

The uPVC formulation that fuels extrusion at REHAU is a closely held company secret. Furthermore, all our raw materials are mixed in-house rather than purchased ready-made from outside vendors. In other words, we know exactly what we’re getting. And so do you!

Proprietary tooling and dies

We design and build proprietary tool and die sets right here at REHAU, giving us a significant advantage over most of our competitors who outsource their tooling. Each die (the keystone to extrusion) is also made with high-grade steel rather than the lower-quality aluminum plates used by many others. The results are window and door profiles with superior structural, surface and mechanical qualities.

Advanced quality assurance

Even when using high-grade materials during extrusion, it is essential to continually monitor and improve every process for quality assurance. That’s why we use the latest computer technologies, research and machinery to test and make sure every one of our window and door systems achieves the tightest tolerances.

Stringent protocols for structural, thermal, acoustical and impact performance

Our mission is to ALWAYS raise the bar on vinyl windows and doors: From aesthetics to operation, energy efficiency to sustainability, structural integrity to innovative design.

Want scientific proof? Every one of REHAU’s window and door systems undergoes stringent testing protocols to ensure that they surpass standards for all the following industry benchmarks:

Exceeds all NAFS structural criteria

REHAU window and door designs – from tilt-­turn, casement and hung/slider windows to French and sliding doors – undergo rigorous testing to meet or exceed air, water and structural benchmarks set by the North American Fenestration Standard (NAFS). Excellence here means a highly durable barrier between indoor spaces and the exterior environment, including infiltration – keeping air and moisture out – and exfiltration – keeping warm or cooled air in. Thicker and engineered uPVC walls also make the product sturdier and thus NAFS-rated for commercial applications as well as residential.

Thermal performance drives energy efficiency

REHAU windows and doors achieve industry-leading energy efficiency by combining proprietary uPVC formulation and extrusion, low-­e glazing capabilities and compression-seal technologies. Fully compliant with all applicable energy codes and ENERGY STAR® ratings, our window and door systems deliver U-­Values as low as 0.13 Btu/hr*ft²*°F.

Perceived noise reduction of 90 to 95 percent

Honking horns, blaring sirens, roaring jets or even a neighbor’s lawn mower – typical urban din, in other words – can seriously compromise quality of life. REHAU windows and doors help wall out these common annoyances by achieving top ratings in sound abatement. Very few vinyl windows on the market today can match this standard.

Hurricane rated for impact and air pressure

Add “hurricane rated” to our long list of certifications in coastal regions where windows and doors are required to withstand hurricane impacts and high wind pressure.

Now you know why there’s “Okay,” and then there’s REHAU

We proudly confess that our German heritage makes us more than a little obsessed with quality engineering. And yes, it takes time and money to continually improve our products. But when your corporate calling is to build the VERY BEST door and window systems in the world, “okay” is simply not good enough.

We call it the The Why REHAU. You’ll call it a competitive edge. To learn more, contact the REHAU dealer or manufacturer nearest you
