Facades represent the face of the buildings. It is a very important aspect in architectural field. In today’s world, facades come in different unconventional shapes, dimensions, etc. As the joint designs are prone to mistakes, they are becoming a prime element in façade design and structure. Therefore we need to abide by some strict rules for a strong and long-lasting façade joint design. The façade tells the story of the building; whether it’s a house, a departmental store, an office, a hotel, etc. It is thus imperative to take into account the technical attributes and the best practices for a façade joint design.
Well-designed façades can also help improve the durability and energy efficiency of the building as well as elevating the level of human comfort. The success of any project rests on the building design as a whole. With a precast façade, it is at least as important as ever to have a confident hand in expressing the architectural theme or the story of the building. You should be clear as to what you want to achieve. The building façade also provides the owner and the architect with a canvas on which to create an image representing the owner’s business, ideals or outlook. Are you a fan of minimalist harmony, layers and textures, or bold expression? Even if you are considering a work of art on the precast facade, the building is much more than a canvas.
Simplicity and Symmetry
Symmetry and simplicity are the fundamentals that architects and designers continue to use because it makes for buildings which are pleasing to the eye. If asymmetry is more your style, consider using simple, clean lines to avoid complicating the design.
Reliable protection against the weather
Building façades play an important role in building aesthetics and in protecting the structural system and contents from deterioration due to exposure to an aggressive environment. The façade is one of the building components most exposed to the weather. This can lead to dirt accumulating on the cladding, which can impair its appearance and function. Rendered or wooden façades are particularly susceptible to this and require regular maintenance or repair in order to avoid extensive damage. Although PREFA aluminium façades are very well protected in this respect, we also recommend regular inspection and maintenance to eliminate the potential build-up of dirt. In the event of a build-up of dirt, PREFA façades can be cleaned very easily. Aluminium is a material characterised by its longevity and, when combined with a protective coating, can withstand external influences and pressures.
Materials to Be Joined
Depending on the design of your facade, it may consist of facade elements of different materials like concrete, glass, metal, brick or stone, just to mention the most common. These elements have to be sealed to each other but also to other waterproofing products like membranes or structural glazing elements consisting of glass, metal frame and silicone adhesives. The sealant must show sufficient adhesion to the materials involved in the joint and at the same time must be compatible with all materials to avoid discoloration, loss of adhesion over time or any changes of properties.
The facade joint width is calculated depending on the expansion & contraction properties of your building elements and the maximum and minimum temperature your facade will be exposed to. Sealants are classified according to the joint width subjected to daily movements it needs to withstand. To simplify your choice, sealants are classified according to their movement class by several standards.
At Healthy Homes, we can help you with all the technical aspects to ensure the facade is truly amazing and at the same time meets the cost efficiency requirements.
