Ventilated facade: device, advantages, disadvantages, reviews

A ventilated facade is a contemporary construction method intended to improve the external walls’ performance and visual appeal. A ventilated facade, in contrast to conventional wall systems, produces an air gap between the insulation and the outer layer of the building, enhancing moisture control and temperature regulation.

A weather-resistant outer cladding, an air gap that usually ranges from a few centimeters to several decimeters, insulation materials, and an inner layer that divides the facade from the building’s interior make up this novel construction technique.

The main benefit of having a ventilated facade is that it can effectively control temperature. The facade helps retain warmth in colder climates and lessens heat transfer during hot weather by allowing air to flow between the layers. In addition to improving interior comfort, this thermal insulation eventually results in significant energy savings.

Ventilated facades have advantages for heat retention as well as architectural adaptability. They can be built with a variety of materials, including glass, metal panels, ceramic tiles, or composite materials, offering a broad range of design options to accommodate various functional needs and aesthetic preferences.

There are factors to take into account with a ventilated facade despite its benefits. Installing the air cavity correctly is essential to preventing moisture buildup, which over time may cause mold growth or structural damage. In addition, compared to conventional facade systems, the initial cost of materials and installation might be higher; however, long-term energy savings frequently make up for this initial outlay.

In general, reviews from builders, architects, and homeowners emphasize how long-lasting and aesthetically pleasing ventilated facades are. Many value the enhanced building performance as well as the chance to design visually arresting facades that are resistant to a variety of weather conditions.

What is a ventilated facade

The external facing of buildings serves the dual purposes of shielding them from the effects of bad weather and contributing to their architectural value. Building exteriors are always subject to the following influences:

• mechanical;
• increased humidity;
• anthropogenic;
• thermal.

Hinged ventilation systems are used to keep outside elements from damaging a structure’s surface. The design is fastened to the building’s wall using bolts and profiles. The ventilation facade’s design consists of multiple layers:

• Frame. It consists of aluminum details. These include brackets, racks, rivets, transverse parts, anchor bolts. The subsystem firmly connects the layers, and also tolerates the weight of the plates to the walls of the building, which prevents vibrations.
• Insulating layer. The composition of the isolation includes hydro-, heat and vapor barrier material (possible combination). Insulation can consist of PPU, foam, mineral fiber. The insulating layer is attached to the walls only by bolts – when using the glue, good adhesion with uneven surfaces will be obtained.
• Protective-decorative layer. Serves to decorate and protects against the influence of precipitation, sunlight.

The insulating layer and the external cladding are separated by an air gap. Its specific dimensions ensure that air masses circulate normally. Gap width: 40–100 mm. Ventilation holes are installed to allow air to pass through in both the upper and lower portions of the clearance. Grates guard holes to keep foreign objects from striking them.

The type of cladding material used produces a variety of ventilated facades:

• porcelain border;
• from algorod tiles;
• composite;
• fiber cement;
• from leanar tiles;
• HPL panels;
• glass;
• Terracoto-ceramic.

There are advantages and cons to the ventilated facade.

The ventilated facade is a modern building technique designed to enhance both the aesthetic and functional aspects of a structure. It consists of an outer layer separated from the building"s main wall by an air gap. This gap allows for natural ventilation, reducing heat buildup in summer and minimizing condensation in winter, which helps maintain the integrity of the building materials. One of its key advantages is improved energy efficiency, as it can insulate buildings effectively, lowering heating and cooling costs. However, the installation can be costly, and proper maintenance is crucial to prevent issues like water ingress or insulation deterioration over time. Reviews often highlight its ability to enhance building longevity and offer versatile design options, making it a popular choice in contemporary architecture for its blend of practicality and aesthetic appeal.

Advantages of the ventilated facade

Ventfasad has many advantages, making it a popular choice for building decoration. Benefits of the facade with ventilation:

• Great noise level and thermal insulation.
• A wide range of materials. You should choose depending on strength, flexibility, cost, etc. D.
• Savings on heating. Suitable for your own houses, where radiators with a thermostat are used.
• High installation speed. Can be mounted at any temperature.
• Suitable for cladding high -rise buildings.
• Resistance to negative weather phenomena.
• Fire safety, corrosion protection.
• Long life. Used up to 50 years.

Ventfasade doesn’t need to be handled carefully. In the event that repairs are necessary, they are completed quickly. The modern city’s architectural style blends harmoniously with the products. Some benefits might turn into drawbacks if a technological deviation was permitted during the structure’s installation.

Disadvantages of ventilation facades

Because the ventilation facade system is expensive, mistakes made during installation will shorten its lifespan. As a result, repairs will be expensive. Notwithstanding their widespread use and numerous benefits, ventilation facilities have certain drawbacks.

• After several years, there may be a shrinkage of the thermal insulation layer;
• through the gaps of the skin, moisture penetration is possible;
• competent design and proper installation should be carried out only by qualified specialists;
• High price of technology.

In many parts of Russia, the use of structures is widespread despite the drawbacks of ventilation facades.

What is the danger of ventilation facades in high -rise buildings

Both new construction and historic building reconstruction use hinged facades. Disasters are occurring more frequently as practical, affordable, and aesthetically pleasing structures gain popularity. The membranes used to guard against wind and moisture are the weakest area of the ventilated facades. When the polymer-based ventilation facade’s components come into contact with open flames, they ignite and help the fire spread.

For example, smokers’ fault frequently results in danger. Some of them shove a cigarette butt that isn’t covered into a ventilation gap after smoking on the balcony. In space, fire spreads extremely quickly. The facade becomes engulfed in flames if the fire starts in just one apartment.

Additionally, there is danger when the facade is raised to a high level. Cars, sites, and lawns below are destroyed if the porcelain tile wall slides. Errors in project or installation preparation are the cause of the collapse. It is imperative to consider variations in temperature and wind loads. The remainder of the plate will start to break away if the wind tears it off. The plates will mate and the design will fall apart if the daily and seasonal variations in temperature were not considered.

Is there any harm to the health of the ventilation facades

Warming the structure’s walls usually requires the application of an extra layer. A material that includes a broken fire decelerator is used as a heater. Smoke gases, which are highly toxic and harmful to human health, are released when an antipyrene fire breaks out.

There are concerns regarding the wisdom of using aluminum alloys in ventilated systems due to their low melting point. At 250–300 degrees, the structural strength of aluminum structures is lost. The entire ventilation facade system, which contains aluminum alloy in its construction, collapses in the event of even a small fire. The material melts and drips if the flame gets stronger, setting everything in its path on fire.

The designs will last a long time if hinged ventilations are made with superior quality and are skillfully designed and installed. In this instance, people won’t pose a threat because the ventilated facades won’t collapse or light up.

A contemporary architectural solution that improves a building’s appearance and functionality is a ventilated facade. It is composed of an outer layer, or cladding, and an air cavity that keeps it apart from the building’s structure. By allowing air to circulate between the building and the facade, this cavity strengthens thermal insulation and provides weather protection.

A ventilated facade’s superior thermal insulation qualities are one of its main benefits. It contributes to the year-round maintenance of comfortable indoor temperatures by minimizing heat transfer through the building envelope. By lowering the need for heating in the winter and cooling in the summer, this can result in significant energy savings.

Ventilated facades provide versatility in terms of aesthetics in addition to thermal benefits. They enable architects and designers to create a variety of visual effects and styles because they are available in a broad range of materials, colors, and textures. Ventilated facades can add to the overall architectural expression and improve curb appeal in residential, commercial, or institutional buildings.

A ventilated facade has benefits, but there are drawbacks as well. The additional materials and labor required for installation can result in higher costs when compared to traditional facade systems. On the other hand, long-term maintenance and energy efficiency savings frequently offset these expenses.

In general, reviews from builders, architects, and tenants emphasize how ventilated facades improve the comfort and performance of buildings. They value the facade’s capacity to reduce moisture accumulation, enhance acoustic insulation, and increase the building envelope’s lifespan.
