Detailed review of the joint ventilation facades

Hinged ventilated facades, another name for joint ventilated facades, are a contemporary architectural design solution that improves a building’s functional efficiency as well as its visual appeal. These facades are made up of an outer cladding layer that has an air gap separating it from the building’s structure. The building’s interior temperature and moisture content can be more effectively controlled thanks to this design, which permits natural ventilation between the wall and the cladding.

Joint ventilated facades are primarily distinguished by their construction, which usually consists of an outer cladding material (such as ceramic tiles, fiber cement panels, or metal sheets), an insulation layer, and a support structure. There are several uses for the air gap that exists between the cladding and the outside wall of the building. It reduces heat gain in the summer and heat loss in the winter by acting as a buffer against changes in the outside temperature.

The potential of joint ventilated facades to increase energy efficiency is one of their main benefits. These facades help to lower energy consumption and operating costs over the building’s lifetime by lowering the demand for heating and cooling. Furthermore, the air gap’s ventilation aids in preventing moisture buildup in the walls, which lowers the possibility of mold development and structural damage.

Joint ventilated facades provide architects and designers with a plethora of creative opportunities beyond their utilitarian advantages. Any architectural style, from sleek modern designs to traditional facades with a contemporary twist, can be complemented by the outer cladding, which can be customized in a variety of colors, textures, and materials.

Insulation for a hinged ventilated facade

There is only one kind of insulation that works well for a hinged ventilated facade: mineral wool. The density of mineral wool needs to be at least 80 kg/m3. The cherished word "valve" is frequently found in the name of the insulation, indicating that its use in ventilation facades is appropriate.

You can lay mineral wool in two layers. Additionally, the bottom layer may have less density. The light series, as it is known. However, density is never going to be less than 50 kg/m3. For the record, you can apply insulation in accordance with the following schemes:

• The lower layer is 50 kg/m 3 + the upper layer 80 kg/m 3;
• The lower layer is 80 kg/m 3 + the upper layer 80 kg/m 3;
• Single-layer insulation 80-90 kg/m 3.

You must use an insulation with a caching layer if you choose not to use a windproof membrane. If not, everything is depicted in the image.

Every choice is accurate. Why, then, use a single density of two layers of insulation? The upper plate of the mineral wool is laid with two layers of insulation, closing the lower row ores. reduce heat loss as a result.

Insulation can be used both with and without a windproof membrane in ventilated facades. The most important thing to keep in mind is that you must use a windproof film if you use a heater without a cache layer. You cannot use a windproof membrane with a heater that has a cache layer.

Five anchors using unique plastic mushrooms should be used to secure each plate of mineral wool. There is only one mount in the center, and the others are in the corners.

When using a windproof membrane, it needs to be overlapped. 10 cm on all sides. The lower film ought to be hidden by the upper.

We discover hinged ventilated facades’ critical role in improving the appearance and usability of contemporary home exteriors in our in-depth investigation of them. This article intends to equip builders and homeowners with crucial knowledge about selecting and putting these cutting-edge facade systems into practice by exploring their design, advantages, and useful considerations.

Methodology for calculating static loads of NVF

As of right now, SNiP II-7-81 "Construction in seismic areas," which offers two methods, is used to calculate loads.

A line-spectral methodology (LST), based on the dissection of the building of the building according to their own forms of oscillations, is applied in the first case, which is typical for all objects.

High-importance structures are intended to be designed using the second technique. The process entails analyzing synthesized accelerograms dynamically and creating instrumental records of the base’s most dangerous acceleration.

The ratio of various load types is also a significant factor in computations. The analysis includes large stock factors as one of its features; these are there to guard against unanticipated risks of the facade collapsing.

Weight load

Weight loads fall into the primary category and vary greatly based on the finishing materials utilized. Their weight ranges from 7-8 kg/m2 to 100 kg/m2 when stone cladding is used.

It’s important to take into account the building’s height, which adds weight, as well as the characteristics of the space where the object is placed. When selecting options for ventilated facades, all of these factors are taken into account in the calculations.

Wind loads

Wind loads are highly dependent on the structure’s height, the surrounding environment, and the wind area. In highly trafficked areas, they may even surpass the weight factors.

The wind pressure is calculated using one of the three types of terrain and the height coefficients as specified by the SNiP "load and exposure" norms.

Holly load

Although this parameter is short-term in nature, it is still important to pay attention to. The weight of the icing may be greater than the finish’s weight. It can be computed using the aforementioned regulatory documents or in accordance with data collected through practical means.

Ventilated facade: installation technology and SNiP

The building’s facade determines how it looks. Any structure can have its face altered by new systems and contemporary facing materials. There are specific requirements for exterior decor. Here, functionality and safety are just as vital as aesthetics.

The ventilated facade is becoming more and more well-liked. The late 1990s saw the start of the active introduction of technology in the home market. Techniques for using it in different climate conditions were developed during this time.

Think carefully about the idea of a ventilated facade, the type of design it is, and its benefits.

What is a ventilated facade

The ventilation facade system, also known as the ventilation facade, is a protective structure that faces the exterior. It is a physical system for isolation from environmental influences that is constructed in two stages and is incredibly effective.

The design is made up of facing materials that are either overlapping monoliths or fixed on the wall’s loading layer and frame. Between the cladding and the wall, a space opens up that allows air to circulate freely.

He takes moisture and condensate out of buildings.

Properly constructed ventilated facade

The entire framework is made up of:

• Proceedings.
• Survey elements.
• Fasteners.
• Insulation.
• Moisture and windproof membrane.
• Air gap.
• Facing.
• Junction elements to general building structures.

The materials utilized for the cladding and restoration (frame) determine the classification.

Types of ventilated facades

You can create two different styles of this type of external facade thanks to the system’s metal structure:

• Vertical.
• Horizontal-vertical.

Buildings with ventilated facades typically fall into one of the following categories, depending on the materials used for the external cladding:

• porcelain border;
• from stone and bricks;
• from planken (wooden board);
• lined, using metal cassettes made of colored galvanized steel;
• with cladding fibros -cement panels;
• with decorative cladding panels made of aluminum composite, terracotta, concrete, thermal panels of polyalpan.

Facade types are separated based on the materials used for the construction’s frame.

• wooden;
• galvanized;
• steel galvanized stained;
• aluminum (using aluminum -based alloys);
• Stainless (premium class, basis – stainless steel).

The selection of materials for ventilated external sections is contingent upon the construction features and budget.

In addition to being functional, the most common types of ventilated facades for private homes also consider the overall aesthetic of the property.

Low-rise building ventilation facades must meet the following requirements:

• waterproofing;
• thermal insulation;
• Noise insulation.

Siding, fiber cement panels, porcelain tiles, clinker tiles, real or artificial stones, and sandwich panels are more frequently used to provide clarity for cottages. They can select a wooden crate to use as a frame. Rebuilding in this manner makes sense when the house is lined with light-colored materials.

The cost of installation of ventilated facades

Think about how to figure out how much material the ventilation project will require and how much it will cost overall.

An illustration of how to figure out how much material will be needed to install a hinged, ventilated facade on a private home is as follows:

Given:

• The house is one -story;
• total area of ​​80 m.sq.;
• construction material – foam block constructive (density 900 kg/m.sq.);
• House dimensions 10×8 m.P.;
• Wall height – 3 m.P.;
• Square of windows:

Task:

Setting up the ventilation facade according to predetermined guidelines:

• insulation – basalt cotton wool;
• The thickness of the insulation is 50 mm;
• facing material – metal siding.

Calculation:

• We calculate the surface area that needs to be closed with a hinged facade:
• The total area of ​​the walls is the area of ​​windows and doors = 98 m.sq.
• We calculate the need for materials:

Typical errors when installing a ventilated facade

• Errors in the calculations. As a result of which, the frame does not cope with the load;
• use of deformed elements;
• change in the technology of the device of the guides;
• unreasonable savings on material, fasteners and tools;
• use of poor -quality insulation;
• Violation of safety precautions.

Tips for the installation of a hinged ventilated facade

• It is better to entrust the calculation and design of the system to professionals, t.To. It is difficult to install with your own hands without experience;
• Check the quality of dowels before the start of work;
• Installation error should be within permissible limits;
• The installation of a paronite gasket between the wall and the bracket will reduce heat loss and allow you to compensate for the movement of the system during operation;
• The installation of the ventilation facade refers to difficult work, so it is advisable to attract serious companies that have authority in the construction market for their implementation.

An appropriately placed and mounted ventilated facade will enhance the exterior appearance and energy efficiency of the home.

Pros and features

The following are the primary benefits of ventilated facades:

1. High rates of heat, hydro- and sound insulation.
2. Resistance to negative effects of the external environment.
3. Fast and convenient installation in any weather conditions.
4. Excellent maintenance in case of unforeseen damage.
5. Reduction of heating costs.
6. A wide range of facing materials, color solutions and design techniques.
7. Durability of operation.

One notable drawback of hinged ventilations is the potential for a sharp drop in fire safety in the event that installation technology is not followed.

For instance, these outcomes may result from wall imperfections, forcing you to use unconventional installation techniques. The anti-corrosion protection and environmental friendliness of materials can be negatively impacted by improper structure installation, shortening their service life.

However, the majority of these risks can be successfully eliminated with the help of skilled specialists.

How to mount with your own hands: installation technology

The installation of the ventilated facade systems should be done on the wall’s previously prepared surface, just like with measures for carrying out regular facade work.

Facade finish installation technology generally uses the following technologies:

1. Preparation of the surface of the walls.
2. Manufacturing and installing the frame for facing.
3. Laying the heat -insulating layer with waterproofing.
4. Installation of facade panels.

Take a closer look at the installation phases.

Preparatory work

The walls’ surface needs to be prepared at this point. Any remnants of the previous finish should be removed, cracks, potholes, and chips should be filled in, plaster should be used to level the surface, and antiseptic compositions should be applied. Processing is required to stop mold and fungal lesions from growing on the walls, which over time can erode the facade’s structural integrity.

It is not necessary to apply a primer when installing a ventilated facade. Generally speaking, surface priming is necessary when finishing work entails painting walls or applying decorative plaster.

What kinds of facing tiles are used on the facade might also be of interest to you.

In this instance, the primer is used to paint the surface and raise the plaster mixture’s clutch forces.

Markings for the locations of the guide profiles and the bracket mount points should be applied to the walls after they have been prepared. One facing panel’s width should be roughly equivalent to the space between the profiles.

Manufacturing and installation of a frame/crate for lining

You can now install the guides and fasteners after applying the marking lines. To accomplish this, use a perforator to drill holes for anchor bolts in the house’s walls.

After twisting the brackets with a screwdriver while they are positioned on anchor dowels, the insulation layer is installed. The thermal insulation material is suspended through fastener-prepared slots.

You must have guides, or metal profiles, arranged vertically. The resultant crate is prepared for the ventilation cloth to be hung. In order to account for temperature deformations, the profile itself needs to be attached freely.

Laying heat and waterproofing

The method used to install ventilated facade systems differs from that used to install standard facade panels in that the former requires the installation of the first overlap, meaning that gaps between joints are not allowed to compensate for the thermal extensions of the facade facing material.

A plate-style dowel is installed into holes drilled into the wall through layers of insulation and windydrumpth membrane. These dowels are used to fix membranes and insulation.

The membrane must be secured to the exterior of the insulation layer, and a 10-cm-wide overlap of material must be noted. The film’s inner side needs to be firmly adhered to the layer of thermal insulation. In this instance, the overlap needs to be sealed with sealing tape to prevent moisture and condensation from building up on the insulation.

Installation of a ventilated facade system

At first look, installing a vent system appears to be very simple, and you might even think that if you know how to work with facade elements, you can install a cladding on your own. Facade panel installation technology, however, has subtleties of its own that if you are unaware of, you risk ruining both the material and the effective design of the crate.

Therefore, it is important to keep in mind that when using galvanized fasteners and profiles for guide crates, they should both be able to support heavy loads—for instance, the same weight of facade elements.

It is necessary to insert a rubber seal for fasteners after fixing into the profile. in order to stop corrosive processes from spreading. Гакупорка воздушной прослойки может возникнуть вентилируемого фасада при самостоятельном монтаже. This results from the insulation layer or membrane settling as a result of inadequate heat and windygid layer fixation. Because the facade panels are under additional load in this situation, the lining may become wet or deform under load if the panels are made of vinyl, which is a finishing material that is both sufficiently fragile and least durable. In these situations, you will need to take the panels off and do the necessary repairs.

System device technology

The system of fasteners, insulation, membranes, and finished facade screen makes up the entire structure. The fastener system is a metal frame that holds facing material and is fastened straight to the wall. Supporting profiles, brackets, anchors, and fasteners are all part of the system. Using unique brackets that go through the insulation layer, the distance between the wall and the facade finish is adjusted.

A membrane that is resistant to moisture is placed on top of a layer of mineral wool insulation. An air gap between the membrane and the facade layer is a requirement. Make sure it is at least 4 cm. Facade finish, the final layer, comes in a variety of materials. Klyamers, the type of which varies depending on the finishing material, are used to fasten the slabs of the material to the frame. If the frame is made of wooden lags, dowels and anchors will be used to fasten them to the wall.

Grand total

The answer to the question of whether or not this system should be used for facing the building may be clear-cut: it is worthwhile. Simply put, there’s no need to skimp on trained labor, high-quality supplies, or taking safety precautions.

Additionally, we suggest that you view this educational video regarding the installation of a hinged ventilated facade:

Device

The components of a multilayer ventilated facade are as follows:

1. The frame subsystem, which is attached to the wall of the building and serves as a support of the entire structure. Most often it is made of galvanized or stainless steel or aluminum.
2. Insulating layer. It is a multifunctional component that provides protection against moisture, steam, wind, cold, and also reduces the heat transfer of the building.
3. Gap for air circulation. It is he who promotes constant ventilation in the system.
4. External decorative shell. Protects the lower layers of the ventilation facade and gives the building a presentable appearance.

Features of the installation of ventilated facades

These crucial guidelines for using hinged facades are all merely suggestions. As a result, developers can cut costs on materials, which frequently compromises both security and quality. In this instance, the result might be the application of prefabricated hinged structures whose component compatibility has been demonstrated. Russian and international businesses both manufacture comparable systems.

The attached facade components that are ready for assembly are usually accompanied by all the required certificates and technical evidence. Regretfully, only 60% of the ventilated facade components that were sold domestically met the necessary certification requirements. However, the quality of the hinged panels and frame components affects not only the ventilated facade’s dependability and efficacy but also its safety.

For anyone hoping to improve the external appearance of their home while also increasing its functional efficiency, it is imperative that they comprehend hinged ventilated facades. Airflow is a key design element of these facades, enabling air movement between the insulation layer and the outer cladding. By controlling the temperature and moisture content of the wall system, this airflow helps avoid problems like mold and decay.

The ability of hinged ventilated facades to increase energy efficiency is one of their main advantages. These facades lessen heat transfer in both hot and cold seasons by establishing a buffer between the building’s exterior and interior. Over time, this thermal insulation lowers heating and cooling expenses while also improving indoor comfort.

In addition to being functional, hinged ventilated facades provide an adaptable platform for creative architectural expression. Because they are available in an array of materials, hues, and textures, homeowners can customize their exteriors to suit their own aesthetic tastes. The aesthetic appeal of any residential or commercial property can be greatly enhanced by these facades, whether one chooses for natural stone finishes or sleek metal panels.

To sum up, hinged ventilated facades are a tasteful fusion of modern design and functionality. By fusing cutting-edge ventilation theories with adaptable external finishes, they improve a building’s aesthetic appeal while shielding it from environmental damage. These facades provide a cost-effective solution that blends functionality and visual appeal, making them an excellent investment in the long-term durability and beauty of any property, whether it is building a new structure or remodeling an old one.
