Aluminum sandwich panels: advantages and disadvantages, step -by -step installation

Here at "All about the Facades of the House," we cover all the information you require to improve the outside of your house. This article focuses on aluminum sandwich panels, which are a common option for contemporary facades because of their ability to combine strength, style, and ease of installation.

Aluminum sandwich panels are made of two thin sheets of aluminum fused to a non-aluminum core, like fire-retardant materials filled with minerals or polyethylene. Compared to solid metal sheets, this construction offers strength without sacrificing weight, making the panels simpler to handle during installation.

The adaptability of aluminum sandwich panels is one of their main benefits. They enable homeowners to create a broad variety of architectural styles because they are available in a variety of colors, textures, and finishes. These panels can be tailored to your preferred aesthetic, whether you like a more traditional appearance or a sleek, modern one.

Their durability is another important advantage. Because aluminum is naturally resistant to weathering and corrosion, it will keep your facade looking great for many years with little upkeep. In addition to offering superior thermal and acoustic insulation qualities, the sandwich panel design further strengthens structural integrity.

Aluminum sandwich panels offer an easy installation process that can be carried out step-by-step using simple tools. This post will walk you through the crucial decisions and steps that come with installing these panels, guaranteeing a polished and durable exterior finish for your house.

The scope of aluminum panels

These leaf materials give dozens of well-known manufacturers worldwide recognition. Each of them came up with different strategies to enhance the technical qualities of their products in an effort to draw in customers. In this sense, there are a plethora of materials on the market with drastically different properties. This allowed for the expansion of the applications for aluminum products. They are employed in rapid construction and manufacturing:

• ventilated facades;
• cladding of the interior;
• advertising shields;
• car van;
• gate;
• wagons;
• interior ships.

Aluminum sandwich panels are typically found on facades:

• Gas station;
• ONE HUNDRED;
• retail outlets;
• entertainment centers;
• metro tunnels;
• balconies.

What are the advantages of sandwich panels?

The most similar substitute for the material are comparable items composed of thin-leaved steel. Even though these products are more robust, aluminum still has a lot of benefits:

• ease;
• Corrosion resistance;
• simple drilling;
• Simplified bending or milling technology.

By using such material, the minimum load on the frame that supports the installation is reduced. When reconstructing a building, you can forgo reinforcing the foundation by using sandwich panels to create ventilated facades. The minimum load on bearing capacity is created by hanging panels, and they can be fixed to the walls without the need for pricey fasteners. There are similar benefits to using this material for roofing. When selecting panels for the production of autofurgons and banners for outdoor advertising, the lightness parameter is crucial.

You can forgo pricey accessories by opting for the panels used in the gate’s manufacture. When installing an electric drive for automatic opening, this is particularly true. If the garage walls are composed of loose material, such as aerated concrete, it will be impossible to hang large structures without building enormous racks. When the gate is lined with aluminum sandwich panels instead of sheet steel, an order of magnitude less load is placed on the walls and fasteners.

Common options for aluminum panels

Although aluminum multilayer panels have been produced for a number of decades, the structure is constantly being improved by manufacturers. A dependable connection between the internal filling and the aluminum sheets on the panel’s sides is made possible by some contemporary connecting materials. Some present striking solutions that allow for a significant deduction from the initial classical production technology. There are four essentially distinct kinds of aluminum panels available on the market:

• composite;
• with insulation;
• corrugated;
• Cellular.

Their technical attributes and thickness parameters differ greatly from one another. Only cellular and corrugated products have general features. Although the names sound similar, aluminum products typically lack the thermal insulation qualities of regular sandwich panels, which are widely used in the construction of frame buildings. Because of this, additional materials such as mineral wool, polystyrene, polystrene foam, or polyurethane are used during the cladding process. Out of all these product varieties, only a specific kind of panel can be utilized as a warming and finishing material.

What are composite panels?

This is among the most widely used materials. It typically has three layers. It has a plastic layer in the middle, and the sides are made of flat aluminum sheets that are adhered to. The front portion can be coated with a variety of decorative materials to give it the required color or unique texture. Additionally, imitation films are frequently used as accents. There are occasions when varnish is applied on top. It can be sealed with a transient transparent film that opens after the panels are installed to guarantee the material is transported safely.

Aluminum composite materials have a fifty-year service life. Due to their high fire safety rating, the panels can be used to decorate both residential buildings and different types of industrial buildings that are at high risk of fire. The panel is not afraid of the effects of precipitation or UV rays because the outer layer is made of aluminum.

It is usually possible to clean the material with water, so you can take care of the facade. Composite material offers good soundproofing qualities, even though the thickness of such products rarely goes above 6 mm. For this reason, they are employed in the budget class to build thin internal office partitions.

Following the installation of the structures, the operating temperature range is between -50 and +80 °C. The material’s decorative layer is resistant to scratches and is particularly impervious to UV light, precipitation, and mechanical stress.

Step 4: Plaster dowels are used to secure the insulation.

Step 5: Attach composite panels to the frame with klyammers and self-tapping screws.

Take note! Similar to how they are used to install the lining, special Klyammers are used to fix these kinds of aluminum panels directly to the frame. The panel itself is not drilled as a result. The Klyammer is mounted on the guide and leaves a 6 mm space between the slabs. The edges of the panels are fixed using the antennae that are present on their surface.

This fixation method ensures that the sheets are arranged with high accuracy and that the joints are spaced equally. The panels are sufficiently fixed by Kleammer’s spring paws to stop deflection due to mechanical forces or wind pressure.

The frame is manufactured using the metallophyle as a guide. The size of the sheets determines the specific distance between each of its racks. Aluminum sandwich panels can be embossed with stiffeners or left flat to be used as facade decoration. Selecting such a material consistently shortens finishing work times and guarantees the creation of a long-lasting, visually appealing surface.

The substance is flexible enough to bend at sharp angles. In order to accomplish this, a shallow mill is run from the future inner angle around the fracture’s perimeter. In addition to removing the aluminum sheet, the cutter also chooses the material for the core composite. The slab becomes overgrown along the line after that. Aluminum sheets of varying thicknesses are used to create composite sandwich panels. The assortment that breaks when bent due to a thin layer of metal makes it unfit for these uses.

Although they have benefits and drawbacks, aluminum sandwich panels are a flexible way to improve the durability and beauty of building facades. This article examines the advantages of using these panels, like their portability and low maintenance requirements, as well as any potential disadvantages, like financial implications and environmental effect. It also offers a comprehensive, step-by-step installation guide for aluminum sandwich panels, so both professionals and homeowners can make well-informed choices when thinking about this well-liked facade option.

Insulated aluminum sandwich panels

This material has a traditional design within the widely recognized sandwich panel concept. There are three layers to it. Extruded polystyrene foam is used as hard insulation in the center, and flat leaf aluminum is bonded to the sides. Typically, epoxy resins are employed as binders.

There are instances of insulated aluminum sandwich panels with a 200 mm cross section being produced in the real world. The thicknesses between 30 and 80 mm are the most often utilized.

Note that of all the aluminum sandwich panel varieties, this material is the only one with heat-insulating qualities. It is used in the production of vans and to create ventilated facades without the need for extra insulation.

Even though the plates’ base is made of polystyrene foam, their rigidity is fairly high. Nevertheless, the material lacks the necessary supporting qualities to allow different fasteners to be installed on its surface. In other words, they won’t be able to tighten the screws holding the shelves and other components in place if the walls are composed of these sandwich panels.

When making car vans with aluminum sandwich panels that have internal insulation, the manufacturer may, if needed, apply carrierly polystyrene foam and press it into the chosen plywood embedded depression. Aluminum sheets are glued to the prepared base later on. Reliability-wise, twisted in the mortgage mount retains no less than welding.

Options for covering insulated aluminum sandwich panels

When ventilated facades are made with this kind of material, installation work can be completed faster and faster. It should be mentioned that there is a lot of this kind of material covering everything, providing any necessary decorative effect. The surface can have a mirror, glossy, shagland, or matte finish.

The name of the coating	Description
Polyester (PE)	Has high protective properties, but not a long service life.
Polyvinyl chloride (PVC)	Durable coating, which has increased resistance to mechanical stress, neutrality to aggressive substances and deep colors.
Oxide film	Is one of the most successful coating options. Has a large operational resource.
Laminated film	Creates an imitation of wood or stone. This material known to the consumer as a coating of MDF and chipboard in furniture of an affordable price segment.

Features of the installation of insulated sandwich panels made of aluminum

Traditional fasteners are used in the installation of this material. It is possible to use bolting connections or self-tapping screws in its quality. The sheets are made with through holes for this purpose, which causes them to be drawn to the base frame. Adhesive compounds are used to process the joints between the panels, preventing the formation of cold bridges. Steel or aluminum corner profiles are used to seal the connection at the corners.

Each side of an aluminum sandwich panel wagon is constructed from a single segment. High rigidity and impermeability result from this. On the frame, sheets are fixed. It is not permitted to use material on frameless constructions.

Hopper sandwich panels

The only ingredients in this material are oxide binder and aluminum. Three layers make up this design. The aluminum that makes up the corrugation is located in the center. The sides of the sheets are glued together. High stiffness is provided by the interior design. The plates’ surface can be processed with a PVDF layer for finishing. Thicknesses ranging from 0.5 to 1 mm of aluminum sheets are utilized in the production of these sandwich panels.

Parameter	Meaning
Thickness	4-42 mm
Weight for 1 m2	3.5 kg
Sheet separation	more than 20 kg
Compression strength for cm2	30 kg

There are several sizes available for this material. Its typical dimensions are 1020 or 1250 mm in width and 2440 mm in length. Since the device of this design effectively transfers temperature, thick insulation is necessary when using the material for lining. The panels don’t catch fire at all.

Two-layer hopper sandwich panels are supplied to the market. They are made of aluminum and an external flat leaf. The panels can flex effectively because there isn’t a single surface present. Because of this, they can be used to complete intricate reliefs, like curved wall buildings.

Out of all the aluminum structures, this kind of sandwich is the strongest. It can be applied in both shipbuilding and the transportation industry in this way. The market-supplied products from Western companies may have different facing coatings. The most popular ones are imitations of skin, fabrics, stones, and wood.

One of the best ways to make a gate is with this kind of panel. Compared to composite panels, this coating will be more resistant to wear. Furthermore, the material is more rigid, which when paired with the collar frame will make it impossible for attackers to penetrate.
