The facade’s design is essential for improving both the external appearance and functionality of a building. A novel method that is becoming more and more well-liked is the hinged facade system with an air gap. This system enhances the building’s structural integrity and energy efficiency in addition to adding a unique architectural element.
The idea is to create a space in between the facade cladding and the building’s exterior surface, which is referred to as the air gap. This space has two functions: first, it improves insulation qualities by acting as a thermal buffer to lessen heat transfer between the interior and exterior. Better ventilation and moisture control are also made possible, avoiding problems like mold and dampness.
The system’s hinged feature describes the facade panels’ effortless opening and adjusting. This characteristic preserves the integrity of the facade while making maintenance and access to the underlying structure easier. Additionally, it offers design flexibility by enabling the facade panels to be finished and made of various materials.
Due to its capacity to balance practical advantages with aesthetic considerations, hinged facade systems with air gaps are frequently preferred by architects and builders. A building can have a sleek, contemporary look while maintaining efficient, sustainable operation over time by implementing such a system.
The concept of a gap
One characteristic unites these designs of airflasts with air gaps, such as the Newton Systems type SKK-SK-003 and the Prime Minister of the MP FC NK KP. This indicates that there is an air gap.
The same holds true for the Hilti VFH Stone, Rosnon 100, diath, Nord Fox, and Phoenix Systems products.
Many steel and aluminum ventilation systems are designed with an air gap as a necessary component. This is among the essential elements.
There are various fundamental uses for the venti-zeal. Specifically:
- compensation for deviations of the size of the walls from nominal parameters;
- rupture of the capillary path of water penetration during the rain deep into the walls;
- the formation of a drainage plane for removing penetrating water to the outside;
- the formation of a ventilation canal in order to maintain the facade dry and reduce the level of humidity inside the building;
- Reducing the pressure difference between the air inside the facade and outside.
Rainwater tries to get through the external facing materials and under the lining because of this pressure differential.
Put simply, companies like Diath, Metal Profile, and Alucom employ ventilation systems to preserve the structural integrity of their walls, which are susceptible to damage from moisture and water. Additionally, this gap benefits the micolimate indoors.
According to design guidelines, hinged facades with an air gap are utilized to line a lot of public and private buildings.
The dimensions of the gap
If there was only one gap, it wouldn’t be sufficient.
Similar to developers, ventilation facade manufacturers work together to create a set of regulations. Ensuring the safety and durability of hinged structures is their mission.
Additionally, the issue is raised at the national level, and pertinent regulations are available. In order to design a hinged facade system with an air gap, they also specify the maximum and minimum gaps.
The set of regulations states that the air gap’s width can range from 40 to 100 mm.
There are comparable norms and standards in Western nations. They only have a 25–50 mm gap.
The different climate is the cause of this. Since it is more severe in Russia, the gap needs to be widened. Furthermore, old buildings’ wall materials and construction quality are crucial. Since a vertical was maintained far from the building site, subsystems must increase the air gap and compensate for the irregularities in the walls.
A gap-filled ventfash is a good way to finish external load-bearing walls. Numerous documents that arose from tests and operational experience govern the installation of these components.
The goal of designing a hinged facade system with an air gap is to maximize a building’s ability to manage moisture and heat. By decreasing heat loss and increasing ventilation, this system—which consists of panels fixed to the building’s structure with a tiny space between the facade and the wall—improves energy efficiency. It keeps moisture from building up, which could result in mold growth or structural damage. In addition to enhancing the building’s environmental performance, the design provides flexibility in terms of aesthetic preferences and accessibility for maintenance. This article highlights the function and sustainability of hinged facade systems with air gaps in modern buildings by examining their advantages, parts, and installation considerations.
Installation procedure
Broadly speaking, I have already discussed the technology used in the ventilation facade installation in a different material. I still want to have some influence on this matter, though.
It’s crucial to follow a specific algorithm and action order when installing such a system.
As a result, the procedure is broken down into multiple phases. Specifically:
- marking for the future design and creating holes in the walls;
- mounting brackets of the subsystem;
- the creation of the necessary optimal air gap in accordance with the standards and a specific situation;
- fastening of thermal insulation materials;
- fixation of wind protection and water protection membrane;
- installation of guide elements and angular structures;
- Fastening of the protective and decorative layer.
Here, everything is standardized and obvious. Regarding ventilation facades, nothing new.
Even though installing hinged systems seems straightforward, it is best to enlist the help of qualified experts. Not everyone is capable of doing such labor with their hands in a qualitative manner.
Advantages and disadvantages
I have to state up front that the price has nothing to do with the merits or demerits of the air gap facades.
The cost is unaffected by the gap itself. When arranging the subsystem to leave a layer of the required width between the building’s wall and the hinged facade, this is solely the installation masters’ responsibility. The problem is multifaceted and dependent on numerous variables.
The design under consideration stands out primarily due to its utilization of the air channel. It is situated exactly in the middle of the wall-attached insulation material and the facing coating. The resulting channel directs air flow vertically, expelling extra moisture outdoors.
The layer’s characteristics enable it to preserve the attachment system’s component parts in a dry state. This stops the metal subsystem and frame from corroding and shields the same insulation from deterioration.
There are a few more noteworthy benefits to be identified. Specifically:
- ensuring effective thermal insulation properties;
- protection against external aggressive influences;
- vibration isolation;
- waterproofing of the building;
- Fire safety increase;
- the suitability of the system for repair by replacing individual components, and not the entire cladding;
- suitability for lining of buildings of different types and age of construction;
- unlimited possibilities in terms of decorative effect.
The cost of heating indoor spaces can be decreased by using such systems with a gap of roughly 30–40%. They do not experience excessive humidity and are warm.
Because wall preservation has no effect, the interior microclimate becomes comfortable and favorable.
If this idea is familiar to you, the dew point is outside the walls due to the ventilation facade.
However, the system is not without flaws. They are primarily linked to the use of combustible materials and the disregard for installation best practices.
The windproof membrane, facing, and insulation material can all light up. The identical vinyl panels start pointing fingers. Manufacturers have a place to aim in this regard.
Furthermore, there is no particular GOST for installing these kinds of systems. Despite the fact that there are guidelines, standards, and suggestions.
Designing a hinged facade system with an air gap requires giving careful thought to both practicality and aesthetics. This creative method improves a building’s aesthetic appeal while also significantly increasing its thermal efficiency.
As a thermal buffer, the air gap inside the facade lowers heat transfer and improves insulation. Over time, this design can result in significant energy savings by helping to regulate internal temperatures, keeping the building warmer in the winter and colder in the summer.
In addition to its thermal benefits, the hinged facade system with air gap has long-term and maintenance-friendly benefits. The opening permits airflow, averting the accumulation of moisture that may cause harm to the structure or the development of mold. It also makes the building envelope accessible for upkeep and inspection without causing significant disruptions.
This design can be used by builders and architects to strike a balance between elegant architecture and environmental sustainability. These facades improve the overall durability and visual appeal of contemporary buildings while supporting sustainable building practices by incorporating materials and technologies that maximize the function of the air gap.
