Construction of the ventilation facade for aerated concrete building

Innovative methods are used in the construction of a ventilation facade for an aerated concrete building in order to improve both performance and aesthetics. Because of its insulating qualities and light weight, aerated concrete needs to be carefully considered when designing facades in order to preserve both its structural integrity and energy efficiency.

For aerated concrete buildings, the ventilation facade system usually consists of an outer layer that permits air circulation while providing weather protection. This arrangement lessens the possibility of moisture buildup and the growth of mold by regulating the moisture content of the walls.

An air gap between the outside cladding and the building envelope is one of the facade’s essential elements. Airflow is made easier by this gap, which enhances thermal performance and encourages natural ventilation. For these advantages to be fully realized, proper installation is essential, and this frequently calls for experts who are familiar with the special characteristics of aerated concrete.

For aerated concrete buildings, ventilation facades are preferred by architects and builders due to their adaptability in terms of design as well as their practical advantages. They provide chances to design aesthetically arresting facades while adhering to sustainable construction methods. In contemporary building projects, the integration of efficiency and aesthetics is becoming more and more valued.

We examine the fundamentals of building a ventilation facade for aerated concrete buildings in this article. The advantages of ventilation facades, appropriate materials for aerated concrete structures, important design and installation considerations, and useful advice for guaranteeing longevity and efficient ventilation will all be covered. Comprehending these principles will enable you to make well-informed decisions to improve the longevity and efficiency of the facade of your building, regardless of whether you’re designing a new construction or renovating an old one.

Wentfasad for aerated concrete: why is it needed

You can forgo the insulation after installing the ventilated facade, which drastically lowers building expenses. However, it’s also critical to keep blocks dry to prevent moisture from destroying them over time.

If the blocks are thicker than 35 cm, insulation is usually not used; otherwise, it is impossible to function without it. It is preferable to abandon the decision to use mineral wool if insulation is ultimately used. It possesses the following qualities:

• small heat transfer;
• less wall thickness, which allows saving building materials;
• saving heating in the winter;
• inside the ventifasads quickly dries.

Crucial! Polystyrene foam does not pass steam well and condensate builds up inside the blocks, so using it is not advised.

Moisture is easily and quickly absorbed by the material’s porous structure, and it can evaporate more quickly thanks to the air gap. The following tasks are carried out by the venti-facade for gas blocks:

• keeps heat in the building;
• Elives accumulated moisture;
• Draises the insulation.

The ventilated facade’s construction lowers heating expenses while extending the blocks’ useful life.

Nuances of the ventilation fiber for a house from aerated concrete

The thickness of the gas blocks varies, as was previously mentioned. It is typically chosen according to the area of residence. If not, you must insulate the walls before working on the facade.

Aerated concrete is a vapor-permeable substance with dual benefits of thermal and constructive insulation. For this reason, building a single-layer aerated concrete wall is advised.

High-quality thermal insulation must be installed if the block is narrower than is advised for this area. If you decide to use polystyrene foam as the material, the walls will become wet and the steam that forms there will freeze at low temperatures. The block will simply be "torn" by the formed ice, which will lessen its functional properties.

It should be mentioned that aerated concrete has vacation humidity, meaning that it will temporarily dry out when moisture strikes. The blocks will dry inward due to the polistyle foam, not a lack of moisture. As a result, the room’s walls will be covered in fungus, mold, and moisture.

Crucial! If polystyrene foam is used for insulation, installing a vapor-permeable membrane and mechanically cleaning the insulation’s surface to remove the glossy layer will improve the glue’s adherence to the plate.

The choice of insulation

Mineral wool should be preferred as a heater. Going outside the building is possible because of its high throughput.

A ventilated gap of 3–4 cm and insulation thickness of 15 cm are the recommended values.

Mineral wool shares similarities with polystyrene foam, which is frequently utilized by builders to insulate homes. Rats will not tolerate mineral wool, but they prefer polystyrene foam, which has nearly the same service life.

The process of working with polystyrene foam is much simpler because, unlike mineral wool, it can be filled with construction foam even if it has small chips and cracks.

Features of installation of a hinged facade for aerated concrete

The design of the hinged ventilated facade is as follows:

• frame;
• thermal insulation;
• waterproofing;
• air layer;
• Finishing.

First, the locations where the brackets are attached must be noted. The construction line is utilized for this purpose. Starting ten centimeters from the corner, the row’s first vertical layer should be placed. It is suggested that steps be taken every 60 cm between fastenings.

1. First, the holes must be drilled for anchors. If the walls are made of blocks, it is important that the spaces do not coincide with the seams. It is better if the distance to the horizontal seam is 2.5 cm, and to vertical – 6 cm. As a fastener, it is recommended to use spacer or chemical anchors.
2. The surface is cleaned of dust.
3. An anchor is clogged, where the anchor bolt will be installed later.
4. Paronite gasket is attached. It helps to avoid cold bridges in the places of drilling.
5. The bracket is installed, and fixed with the anchor.
6. At first, the anchors are clogged with a hammer, and then, twisted with a screwdriver.
7. The holes are made in mineral wool where the brackets are inserted.

Crucial! Wearing a specific protective suit is required when working with mineral wool.

• The slabs are mounted on the bracket, after which clamping washers are installed on the latter.
• The plates are joined. The insulation begins to put from the bottom up, at a distance of not more than 2 mm from each other.
• DOBORTS are installed. At the corners, you must follow the gear dressing of the seams when one plate comes into another.
• Holes for plate dowels are drilled. With the help of dowels-grites, the slabs are fixed mechanically.
• Fixing the plates. To ensure reliability, they are attached at five points, in the corners and in the center. If this is half the plate, then 4 mounts are enough.
• The second layer of insulation is mounted. If you need a second layer, then the first should have a smaller density, and be attached to two dowels. The upper layer should be much denser, and fixed with five dowels.
• Connecting elements for insulation are installed.
• A profile stand is mounted – these are supporting guides that are attached to the bracket.
• Profiles are joined at the ends. The gap between the profiles should not exceed 8 mm.
• Clamps are installed – these are fastening elements, the type of which depends on the facing material.
• The cladding is a decorative finish; the gap between it and the insulation should not exceed 10 cm. Otherwise, in a strong wind, the facade will “buzz” strongly, and in a lesser wind, the moisture will not be able to be completely removed, as a result of which the insulation will rot and become damp.

When choosing polyurethane foam for insulation in a ventilated façade for a private home built of aerated concrete, the vapor-permeable membrane is attached.

Selection of fasteners

Because the structure of aerated concrete blocks is porous, the selection of fastening components is an equally important step. If this isn’t considered, the thermal insulation will eventually peal off and the sheathing’s integrity will be weakened, which will cause cold bridges to form and the walls to collapse.

It is preferable to use chemical or mechanical anchors, springy dowels, dowels-gvo, or other dependable and long-term fixation methods. These are separated into four categories: universal, clogging, spacer, and springy.

Surveys that are mechanically generated are more appropriate as a fading facade for gas concrete. After they are securely embedded into the block’s thickness, the fasteners can be screwed in.

The chemical method is equally dependable; after the resin is poured into the hole, it solidifies and fixes the bolt and anchor. The solution forms a sealed mount upon hardening.

Crucial! The weight of the cladding and the profile (wood or metal) that is being used determine which fastening is best.

Constructing a ventilation facade for an aerated concrete building requires careful planning and accurate construction. It is more than just an ornamental piece; it is essential to preserving the structural integrity and thermal comfort of the building.

Ventilation facades work well with aerated concrete because of its insulating qualities and lightweight nature. These facades let in air circulation, which helps control indoor temperature and humidity levels, while also creating a protective layer against the elements.

Selecting premium materials is essential when building such facades. Choosing breathable insulation and sturdy cladding guarantees efficiency and longevity. For the facade to remain effective over time and to avoid moisture buildup, proper installation is equally important.

Additionally, adding beautiful details to the design makes the facade more visually appealing and harmonizes with the building’s overall architecture. This raises the property’s value in addition to enhancing curb appeal.

In summary, an aerated concrete building’s well-designed ventilation facade blends practicality and beauty. It encourages ideal indoor conditions while offering crucial weather protection. Homeowners can benefit from a robust and aesthetically beautiful facade that raises the value and comfort of their property by selecting the appropriate materials and making sure that the installation is done carefully.
