SUN BREAKER - SUNSHADES

Sun Breaker (Sunshades) systems are assembled from steel and aluminium in order to control daylight in spaces and to save energy. It has a wide range of products in different shapes and sizes. Thanks to the possibility of special production, it provides different alternatives to designers. Sun shading systems that can be used horizontally or vertically can be applied as fixed or mobile, and in mobile options, it provides optimum shading by manual or motorised control. All Ral Coded Colour Options, Anodized, and Natural Wood coating method are applied.

Modern dynamic facade solutions
Innovative protection against sun and adverse weather conditions
Corrosion-resistant aluminium and stainless steel material
Connection to surfaces inside the window opening or to the outer shell
Energy saving advantage
It ensures that the sun's rays do not enter the buildings with its control
Durable fixed or movable options

Fixed Sun Shading

Vertical fixed sun shades: Generally preferred on east and west facades. They are effective in blocking low-angle sun rays that change throughout the day.
Horizontal fixed sun shades: They are mostly used on south facades. In summer, they block the sun coming in at high angles, while in winter they allow the sun to enter at low angles.
Hybrid (vertical + horizontal) combinations: Used on mixed facades, they provide both horizontal and vertical protection

Perforated and Mesh Sunshading:

Perforated metal sheets: Perforated metal panels create shade and design effects while filtering light.

Metal Mesh : They are in the form of metal or textile nets. Can be applied like facade cladding.

Screen facade (double skin facade): Provides air circulation between two-layered facades, giving a passive cooling and shading effect.

Motorized Sun Breaker

Motorized solar shading systems usually have systems that can be automatically adjusted to provide daylight and shading.

Manufactured from aluminum or steel, they can rotate up to 90 degrees, providing dynamic solar control and thermal comfort.

These systems are available in vertical or horizontal configurations and can be designed with perforated panels or mesh panels to provide both effective shading and architectural appeal.

Integrated automation allows them to react to solar position, light intensity or wind speed, improving energy efficiency by reducing glare and lowering cooling loads.

Architectural Sun Shading Options

Vertical Shading

Vertical sun shades are an excellent alternative where greater control over direct sunlight is required. The choice of horizontal or vertical sash orientation is largely determined by a combination of form and function. Form is architectural preference, function is the amount of sunlight interception required and the orientation of the building.

Vertically oriented sashes are usually used on full east or full west facing facades where glare from low angle direct sunlight is a problem. In this case, depending on the sash spacing, a sash mounting angle of 90° eliminates almost all direct sunlight, while providing optimal visibility and reflection of diffuse light back into the building.

Perforated & Mesh Sunshade

Perforated and Mesh Sun Shading Systems offer ideal solutions for both new constructions and renovation projects. While providing a modern look, they ensure shading, exterior view visibility, and natural air circulation.

In summer, they block high-angle sunlight, keeping the interior cool, reducing glare and letting in soft daylight. In winter, low-angle sunlight passes under the panels and contributes to passive heating of the interior. Components such as hole ratio, mesh type, and carrier system can be customized according to the project, thus providing a functional and aesthetic solution.

Horizontal Shading

Horizontal canopy designs are ideal for both new and existing construction. They provide effective shading while maintaining unobstructed views. Projection and blade size can be modified to suit project requirements.

This sun shading design is most effective for use on facades facing South-East to South-West. During the summer months the building will be protected from high intensity direct sunlight, while light diffused light will be allowed to enter the building. During the winter months, however, the lower position of the sun will allow direct sunlight to enter the building from under the canopy, providing limited solar gain to support the building's heating system.

Motorized Shading Systems

Motorized sun shading systems provide comfort and energy efficiency by offering automatic control on building facades. Thanks to their durable structures made of aluminum and steel, they offer long-lasting use.

German and Italian origin, high performance motors are generally preferred in the systems. They can be integrated with remote controls, building automation systems or sensors. While contributing aesthetically to modern architecture, they also play an active role in climate control.
