Product Overview 

The OS2 65 system is a thermal break window and door system designed for modern living. It boasts ultra-slim profiles of just 27mm, allowing for expansive glass areas that bring light into your home while maintaining a minimal, clean appearance. With a central node of only 62mm between sashes and a frame depth of 65mm, the system is designed to house glass up to 40mm thick, providing excellent thermal insulation and noise reduction.

This versatile system offers a wide range of opening options, ensuring the same sleek profile is maintained throughout all window and door types. Whether you need hinged, tilt-and-turn, or pivot openings, the OS2 65 system allows you to choose the perfect configuration for your project. Additionally, with over 40 profile options, you can select the precise look and functionality that best suits your design vision.

Product Features 

The OS2 65 system offers an array of features that make it one of the most versatile and high-performing exterior systems on the market. The minimal profile, combined with the ability to accommodate up to 40mm thick glass, ensures that these windows and doors provide excellent thermal efficiency without compromising on style. With slim central nodes of just 62mm, the sightlines are kept clean and minimal, offering uninterrupted views.

You can choose between two subsystems—OS2 65.1 and OS2 65.2. The 65.1 option offers sashes that are easily distinguishable, with non-flush-mounted glass panels. On the other hand, 65.2 provides a seamless design with flush-mounted glazing and nodes that remain consistent across sashes and fixed panes. This flexibility allows you to tailor your windows and doors to your specific needs, whether you prefer a more defined or sleek, uniform appearance.

Design and Engineering

RK Steel Exterior Windows and Doors are engineered for both form and function. The OS2 65 system includes over 40 profile options to meet a variety of design and functional needs, ensuring the right solution for every project. From slender frames that house non-flush glass panels to options that keep the frame and glass flush for a uniform look, the design possibilities are endless. The profiles can also be tailored to enhance the edges of the glass, either making them stand out or rendering them nearly invisible within the façade.

In addition to the wide range of profile options, the glazing beads available are also integral to the design, with different shapes such as squared, triangular, thin, and rounded square—all produced in the same finishes as the frame for a cohesive aesthetic. Hinges are available in stainless steel or corten steel and can be concealed, further enhancing the minimalist look of your windows and doors. RK Steel handles, in finishes like brass, corten steel, and stainless steel, integrate seamlessly into the frame, offering a geometric and discreet design that complements the overall aesthetic. RK Steel Exterior Windows and Doors are available in various materials and finishes, including galvanised steel, stainless steel, corten steel, and brass, with customisable options like the bi-material OS2 65 system, allowing for tailored interior and exterior designs.

Security and Energy Efficiency

The OS2 65 system is designed with a thermal break, ensuring superior insulation and helping to maintain a comfortable indoor environment regardless of weather conditions. With glazing up to 40mm thick and minimal profiles, these windows and doors meet modern thermal performance standards, reducing heat loss and enhancing energy efficiency.

Additionally, the robust steel frame construction and discreet, high-quality handles ensure maximum security. The windows and doors can be fitted with multi-point locking systems and internal glazing beads to prevent glass removal from the outside, ensuring your property remains safe and secure.
