RAY Windows: frameless all-glass minimalism for sophisticated interiors

The concept of all-glass and frameless windows

In the world of contemporary architecture, the window has long since ceased to be a purely functional element. It has become an integral part of stylistic language, helping define space, light and the visual identity of each environment. It is precisely within this new concept of living that RAY finds its place: the frameless, all-glass window system designed by Caiframe, one of the most advanced and refined solutions currently available on the market.

Often referred to as “all-glass windows,” this type of frame stands out for a structure where glass dominates the visible opening, both inside and outside the building. In the RAY model, the design achieves the highest level of formal purity due to two distinctive features: an ultra-slim internal sash (just 45 mm thick) and the complete integration of the frame into the wall, resulting in a flawless flush finish.

On the exterior, the result is a perfectly smooth reflective surface with no visible trim. This mirror-like effect is made possible by a concealed aluminum cladding and a purpose-designed subframe, allowing the sash itself to visually “disappear” - earning it the nickname “hidden sash.”

More light, less obstruction, maximum visual impact

The benefits of such a solution are immediately apparent: generous natural light, thanks to the expanded glass surface and the absence of visible structural elements. The result is brighter interiors, uninterrupted panoramic views and a contemporary aesthetic fully aligned with current architectural trends.

These visual advantages are matched by excellent performance. RAY all-glass windows provide optimal thermal and acoustic insulation, actively enhancing indoor comfort while reducing energy consumption. The combination of laminated wood and aluminum forms an effective barrier against heat, cold and noise, with Uw values significantly lower than the market average.

A high-end architectural choice

Increasingly used in high-spec projects, such as modern villas, luxury homes and upscale residential developments, RAY frameless windows are appreciated not only for their aesthetics but also for their technical sophistication. The desired visual effect can only be achieved through precise installation, high-performance materials and an integrated design approach from the earliest stages of the project.

This is where Caiframe’s experience makes the difference: every detail of the RAY system is designed to simplify installation and ensure a result that perfectly reflects the architectural vision.

Technology meets materiality: the Caiframe signature

One of RAY’s key differentiators in the world of minimal windows is the use of genuine laminated wood, a material that brings warmth and authenticity, enhancing both the tactile and visual quality of the product without compromising on performance. Carefully paired with exterior aluminum cladding, it ensures a window system that is durable, stable and virtually maintenance-free.

Glass remains the central element, with a continuous surface that amplifies natural light and creates a seamless transition between inside and outside. Concealed hinges and the absence of visible trim further elevate the total glass effect, producing a result that is both understated and visually striking.

Customization and versatility

RAY is not a standard solution: it’s a modular system designed for complete customization. Handles, trims, wood or aluminum finishes, neutral tones or natural shades: every detail can be tailored to match the specific design vision and aesthetic of the space.

This flexibility makes RAY an invaluable resource for architects, interior designers and specifiers who need a solution that integrates effortlessly into any style — from pure minimalism to warmer, textured interiors — without forgoing technical quality.

One window, many applications

Thanks to its flush-mounted design, premium materials and excellent performance, RAY is suitable for a wide range of architectural settings: private homes, renovation projects, historic buildings (where visual discretion is key), as well as boutique hotels, showrooms and contract environments where elegance must go hand in hand with reliability.

It is precisely this blend of technology, aesthetics and function that defines Caiframe’s identity — an Italian company with over fifty years of experience in advanced window systems, always focused on innovation and detail.
