By the time you’re done, you’ll know exactly how to install brick cladding on top of aerated concrete, giving your house a stunning and long-lasting new look. Let’s get into the specifics and begin working on your upcoming home renovation!

Why is cladding needed

Because of their accessibility, low weight, and effective thermal insulation, aerated concrete and its derivatives are highly sought-after building materials.

To create the material, simply prepare the lime, sand, and pore-forming ingredients, then combine them in a specific way.

However, because aerated concrete structures have pores and collect water, they start to deform when exposed to moisture. Wet walls and poor resistance to frost result from this. Extended periods of precipitation worsen the situation. Brick is used to conceal the aerated concrete from the damaging effects of moisture.

Furthermore, even painted, aerated concrete lacks a presentable appearance. Thus, the only way to achieve a fashionable and attractive exterior is through cladding activities.

Although there are many options for finishing (such as block houses, siding, and ceramic tiles), brickwork is advised by builders for the building’s exterior.

Pros and cons

Brick finishing is very popular because of the following benefits of the material:

1. Long service life – bricks can last more than a hundred years.
2. Resistance to subzero temperatures and weather changes. Brickwork is not afraid of frost or precipitation.
3. High strength properties.
4. Presentable design and a wide variety of textures. In addition to traditional brick, you can find glazed or textured varieties on sale.

Facing work can be done during wall arrangement as well as building finishing. The second option improves defense against precipitation, frost, and other adverse effects in addition to altering the look of the walls.

The high cost of the material and the requirement for some masonry skills are the drawbacks of brick finishing. If the installation guidelines are disregarded, condensation will start to build up in the wall’s crevices.

Brick cladding technology for aerated concrete homes uses a variety of fastening techniques to guarantee longevity and a polished appearance. This post will discuss various methods, including adhesive bonding, mechanical anchors, and integrated wall systems, and offer a detailed how-to for creating a safe and attractive brick facade. Knowing these fastening options will help you choose the best method for your project, ensuring strength and style for the exterior of your home, whether you’re a professional builder or a do-it-yourself enthusiast.

Types of cladding

Four brick cladding options are available:

1. Without a gap.
2. With an air gap without a heat-insulating layer.
3. Cladding with insulation and ventilation.
4. Cladding with thermal insulation, but without ventilation ducts.

Another approach allows for the existence of an air gap but excludes ventilation. However, aerated concrete is prone to deformation and deterioration due to the intense accumulation of vapors; therefore, this type of finishing is not very popular.

Examine the benefits and drawbacks of each approach to decide which is best for laying brickwork in an aerated concrete home.

Without a gap

Such a project not only doesn’t add to the room’s durability or improved thermal insulation, but it can also hasten the process of wall deformation. But using gap-free brickwork for the finishing touches is a great way to decorate a building that isn’t heated. The cost savings on facing and insulating materials, along with the ease of installation, are the benefits of this method.

With a ventilated gap without insulation

For the majority of homes, ventilated mesh and air gap cladding is thought to be the best choice. In this instance, moisture removal is guaranteed by means of specific holes that create a tiny space between the wall composed of gas silicate blocks and the brickwork. Since air is the best heat insulator, the method’s primary benefit is the decrease in heat loss.

1. To protect your home from the cold, you will need to correctly determine the thickness of the layer and the placement of ventilation holes. If the air circulation is excessively strong, the penetration of cold air masses into the building will worsen the thermal insulation capabilities.
2. A wall with such insulation is thicker, which increases the cost of material for finishing the basement.
3. The formed voids attract small rodents and insects, which begin to destroy the structure. To prevent this, it is enough to secure special fine-mesh meshes in advance.

With ventilation and gap filling with thermal insulation material

One effective way to guarantee complete building insulation against cold penetration without compromising ventilation capabilities is to fasten facing bricks to aerated concrete with a ventilation gap and insulation.

The following kinds of insulation work well with this solution:

1. Glass wool.
2. Mineral wool.
3. Other vapor-permeable materials.

The thickness of insulated walls is comparatively small, and the installation and insulation costs are in addition to the base costs.

Non-ventilated gap with insulation

The latter option uses air-hole-free expanded polystyrene sheets as insulation. Buildings made of aerated concrete that have an opaque vapor barrier—which may be made of foam plastic—can use this solution.

In this instance, the lined wall’s performance attributes will be enhanced, and the cost of installation will be reduced.

One of the disadvantages of the design is the flammability of foamed polystyrene, but in practice this is not true. To enhance fire safety during production, the material undergoes processing with specific heat-resistant additives.

Additionally, two strong non-flammable insulators are applied to the surface.

Facing device technology

Prior to attaching the facing brick to the gas block construction, it is crucial to thoroughly examine the technology underlying the device at this layer, t.To. Depending on the kind and state of the building, it may vary.

During the construction of a new structure

New home cladding allows for the building of a solid foundation by accounting for the thickness of all layers and future walls. Only after waterproofing the entire wall structure do the builders start building the wall.

In the process of building, you must choose which to begin with:

1. Construction of a brick wall.
2. Construction of a gas block structure.
3. Combination of both methods.

These concerns stem from the fact that aerated concrete components can be joined together using glue and that brickwork features more height-related seams. There is a variation in shrinkage in this sense.

Ties for fastening aerated concrete and brick for a new building

Fiberglass ties are required to join aerated concrete and brick when cladding a new home. These are reinforced items that can be purchased from a store or made by hand from wire or rod that has an ideal cross-section. At the same time, fiberglass alternatives that don’t mind corrosion processes start to be sold alongside traditional steel products.

It’s crucial to pay attention to proper anchoring when putting in wall ties. They are incorporated into the solution for this reason, separated by ten diameters.

For the walls of an already operating building

A number of steps must be taken to set up the foundation for future masonry if covering a finished house with aerated concrete is desired. Because the weight of the roofing cake and ceiling will affect the main foundation, the type of foundation is not as important as its ability to support the additional load from the bricks.

You can use screw piles or a columnar foundation if the soil is stable. It will be necessary to use foundation beams to secure the masonry support.

Dowels are used to secure the ties, and washers are used if at all feasible. In blind holes, glue fastening is an additional option. Self-anchoring bolts are the best option for fastening because they provide dependable, fast fastening in seams and blocks.

Type of Fastening	Description
Wall Ties	Metal ties are embedded in the mortar joints of the brickwork and connected to the aerated concrete wall to provide stability and support.
Brackets	Metal brackets are fixed to the aerated concrete wall, and the bricks are anchored to these brackets for additional strength.
Adhesive Mortar	A special adhesive mortar is used to bond the bricks directly to the aerated concrete wall, ensuring a secure attachment.

Aerated concrete homes benefit from the added layer of protection that comes with brick cladding in addition to their improved aesthetic appeal. Brick cladding can be securely fastened using a variety of techniques, each with a unique set of benefits. Knowing these options enables homeowners to select the approach that best suits their unique requirements.

The most popular techniques involve the use of reinforced mesh, wall ties, or a mix of the two. Wall ties are metal fasteners that provide stability and guarantee the bricks stay firmly in place by joining the aerated concrete to the brick cladding. However, the weight of the bricks is distributed more equally across the surface when using reinforced mesh, which can be especially useful for larger structures.

Regardless of the approach you take, installation must be done correctly. This involves making certain that the mesh or ties are firmly fixed into the aerated concrete and appropriately spaced. Frequent inspection and upkeep of the cladding system can avert possible problems and guarantee that the external appearance of your house is long-lasting and attractive.

In conclusion, brick cladding gives aerated concrete homes a unique combination of style and utility. Homeowners can benefit from an aesthetically pleasing and long-lasting exterior by carefully considering installation details and choosing the appropriate fastening technique. Your house will look fantastic and stand strong for many years to come with the correct approach.
