Cortizo COR 80 Industrial is a window that shatters the myth that "only plastic can be warm." Cortizo engineers have created an aluminium system that surpasses most PVC profiles on the market in thermal insulation performance. The secret lies in scale: the 80 mm installation depth allowed integration of a massive 45 mm wide thermal break filled with special foamed polyolefin inserts. This creates an insurmountable barrier against cold and heat.
This system is designed for the most demanding projects where every detail matters. Passivhaus certification confirms that COR 80 is perfectly suited for zero-energy buildings. Beyond extreme thermal insulation, the profile boasts outstanding structural rigidity, capable of supporting heavy triple-glazed units weighing up to 120 kg (and more with concealed hinges). The "Industrial" series aesthetic features strict straight lines that emphasize the premium status of the property and the modern taste of the owner.

FAQs
In the case of COR 80 — yes. Thanks to the 45 mm thermal break and special foamed material inserts, this system outperforms standard 70 mm PVC windows in thermal insulation. It is a technological masterpiece combining the strength of metal with the warmth of plastic.
Yes, if you value comfort and savings. In summer, such insulation acts as a powerful shield against heat, keeping air conditioning coolness inside. In winter, it eliminates the "cold wall effect" near the window. Plus, it is the standard of the future, increasing your property value.
The Industrial line features a complete absence of rounded edges. Glazing beads, frame, and sash have straight angles and sharp edges. This creates a strict, architectural appearance that perfectly complements modern facades, concrete, stone, and metal.
The 80 mm depth is required to accommodate the wide thermal break and ensure structural rigidity. This allows for larger and heavier sashes than narrower systems, without risk of deformation from wind or self-weight.
COR 80 belongs to the premium class in terms of security as well. The profile allows installation of armoured glass and the highest class burglar-resistant hardware (up to RC3). It is a true glass safe that protects the home not only from weather but also from intruders.
Absolutely. The ability to install 65 mm glazing units allows the use of special acoustic glass compositions with varying thicknesses and films. Combined with three seal contours, this reduces noise by 46 dB, creating a feeling of vacuum-like silence.
