Metal facades add sophistication and modernity to buildings. Metal facades add sophistication and modernity to buildings. The main concern when working with metal facades is the possibility of corrosion. This can cause weakness in the material and affect the aesthetics of the building. With this in mind, architects should consider what they can do to ensure that building envelopes age gracefully while still maintaining aesthetics and performance.

You can do this in two ways: by carefully detailing the project and choosing the best materials and products to suit the specific project conditions. Most metal facades are made using a cut and fold design. This is usually manually sealed and then painted. This system has the disadvantage of allowing corrosion to spread and creating undesirable effects on the facade. Trimo developed the Qbiss One product. This metal modular wall system is made of steel and features unique corners to prevent cuts and folds. This design was created using state-of the-art engineering techniques and the most recent automated technology. Designers can explore the unique corners to create a stunning aesthetic. They also avoid any corrosion risk that may occur in traditional metal facades.

Qbiss One is also more practical than built-up systems, and it’s easier to install. This allows for a 30% faster installation of your facade envelope.

This product is made up of two galvanized steel sheets prepainted and bonded to a core of non-combustible mineral wool A1 (non-combustible). The three layers make up a prefabricated facade element. It is a composite element that has a thermally insulating core and is fire resistant. The most common form of flat rectangular-shaped elements are those with different dimensions. There are also L-formed elements that can be used to build corners and other forms for special purposes. These elements can be attached to primary or secondary steel supports easily and span up to 6,5m (subjects to structural calculations). To prevent water from entering the system, each element is equipped with gaskets at the corners. This ensures long-lasting performance.

The three-layer steel sheet coating is durable and strong. It has been proven through extensive testing that it can last up to 50 years. Mineral rock wool, an insulating material made of stone of volcanic origin, is used to contribute to thermal insulation. This makes the product suitable for “green building” and allows it to be recycled. Continuous thermal insulation is used to eliminate thermal bridges. The fire resistance function of the non-combustible core of mineral wool prevents fire spreading. The product’s thermal insulation is excellent and ensures that the building uses very little energy to heat or cool it.

It is important to think about the future destination of construction materials once the building has ended its useful life. Steel products can be recycled at a rate of more than 90%. This is significantly lower energy consumption than what was required to make the original product. Trimo claims that the Qbiss One steel wall system can be recycled up to 99%.

It is important to be able mix and match aesthetic options. Galvanized steel sheets can mimic stainless steel and look just like it. Trimo created ArtMe to maximize artistic creativity. This unique facade design allows for a variety of shapes, patterns, and visual effects that can be displayed on the facade. The possibilities are limitless when it comes to photos, branding, logos and custom creations using 3D technology with embossed design.

The Golden Hall project by A4 Studio was externally coated with golden metal. This refers to past and current success of the winning sports club. The metal plates have inscriptions that show past and current champions. The projects Brunner Innovation By Henn, HOMEby Mecanoo, and Ice Hockey Stadium Of Ondrej Nepela were designed by Fischer Architects. The matte gray metallic facades contrast well with the predominant glazed surfaces that use the Qbiss One product.
