It’s All About Size – Large Windows & Narrow-Sight-Line

The hottest and most dominant trend in the world of luxurious construction projects these days is undoubtedly large, wide windows which create the perfect connection between indoors and outdoors. The demand for these windows by leading Architects has risen, since they value the unique illumination natural light provides for the house interior.

Along with the demands for wider openings comes the need for a thinner profile, which creates a clean vibe that doesn’t block out the view.

Windows with a classic design, characterized by many divisions, require excessive attention to the thickness of the profile. Slim Profile Windows enable flexibility in design and maintain a clean and optimal appearance.

Steel’s main advantage is its strength and resilience compared to other materials such as aluminum, wood or PVC. This enables manufacturing of very large window profiles with a thin and sleek look, allowing minimalistic planning and almost unlimited artistic freedom on the Architect’s end.

Thermally Broken Profiles & Advanced Insulating Glasses: Low U-Factor

New Steel Profiles with Thermal Breaks produced by Ottostumm (Switzerland) enable the production of Steel-Windows and Doםrs that matches the Thermal performance (U-Factor) of Wood or PVC windows.

Incorporating advanced Insulating glasses with LOW-E coating with Significant Air-Space and new silicon based spacers can result in a very low U-Factor that can even comply with the most stringent thermal isolation requirements (California’s “Title 24” for example).


Advanced Rust protection – Zinc Metalizing

Humidity, heat and proximity to the sea create tough climate conditions that may accelerate rusting processes. This is one of the main reasons why cheap production has created a bad reputation for Steel-Windows.

Professional coating of the steel ensures full protection from rust, and enables sheer enjoyment of the product’s unique advantages.

In order to promise the perfect protection for years to come, Tuval applies an advanced and expensive galvanization process called Thermal-Spray, Zinc Metalizing. As opposed to regular electrostatic galvanization, the Thermal-Spray (of the melted Zinc) creates a thicker coating layer, which covers the entirety of the product’s surfaces, including corners and welding points.


Operational enhancement

Alongside our Steel Frame Window’s elegant and design apparel, we strive to create comfortable and easy to use operational solutions. Each and every window is planned specifically per project, so that both its apparel and technical attributes can be matched upon request.

Tuval has developed a number of mechanisms that enable the optimal combination of design, easy operation and lifelong reliability. For example, we offer advanced multi-point locking mechanism, custom-made hinges with a minimalistic profile, a unique system for sliding Steel Frame Windows, Bi-Fold solutions, and more.

We at Tuval are working around the clock on new improvements and additions to our products. This is how we promise our customers and architects the most advanced and exclusive solutions on the market.
