Born in 1948 in a small Bavarian town, REHAU began with a single extruder and a curiosity for how polymer science could outmatch traditional building materials. Today, it remains an independent, family-owned enterprise that prioritizes generational longevity over quarterly metrics, specializing in high-performance polymer systems for windows, hydronic heating, and interior surfaces.
Why we chose REHAU
In our region, temperature swings of eighty degrees in a single week are not uncommon. We chose REHAU because their chemistry is specifically engineered to survive these extremes where standard vinyl becomes brittle and aluminum frames allow heat to migrate through the building envelope. Their materials remain stable from -20°F to 100°F, providing a level of mechanical reliability that safeguards a home’s structural integrity and thermal comfort in the harshest Lake Superior winters.
Application
RAU-FIPRO Windows Standard uPVC profiles rely on a steel core for rigidity, which inadvertently acts as a thermal bridge, drawing cold into the interior. REHAU replaces this with RAU-FIPRO, a fiber-reinforced composite that achieves aerospace-level stiffness without the metallic heat loss.
Engineered for Passive House standards to maximize energy retention.
Maintains structural tolerances under extreme thermal expansion, ensuring gaskets stay sealed and airtight.
Supports larger fenestration spans without the risk of the frame bowing or warping.
RAUVISIO Surfaces For interior millwork and cabinetry, RAUVISIO panels solve the common issue of delamination in high-moisture environments. Instead of traditional adhesive-based edge banding, REHAU uses a laser-welding process that fuses the edge directly to the surface.
Eliminates visible glue lines that traditionally trap dirt or peel over time.
The surfaces are UV-stable and scratch-resistant, providing the aesthetic of glass or stone with the impact resilience of a polymer.
