Facade sandwich panels: varieties, installation methods and advantages of use

Sandwich panels for the facade provide a flexible option for contemporary architecture that combines practicality and visual appeal. These panels are composed of three layers: two outer layers, usually made of aluminum or metal sheets, and an inner core made of insulating material, such as mineral wool or polyurethane. This design is a popular option in both residential and commercial architecture because it not only improves the aesthetic appeal of buildings but also offers excellent thermal insulation.

The variety of facade sandwich panels is one of their main benefits. Architects and designers can create a variety of visual effects and styles with them because they are available in a range of thicknesses, colors, and textures. These panels can be tailored to fit a variety of architectural tastes, whether they look like classic materials like stone or wood or provide a sleek, modern appearance.

Facade sandwich panels are becoming more and more popular in construction projects because they are relatively easy to install. Compared to conventional building materials, the panels are easier to handle and install because they are lightweight but durable. Builders can save money by using facade sandwich panels because of their simple installation, which also cuts down on labor expenses.

In addition to their practical and aesthetic advantages, facade sandwich panels have excellent thermal insulation qualities. The insulating core increases energy efficiency by reducing heat gain in the summer and heat loss in the winter, helping to control indoor temperatures. This feature lowers the building’s overall energy consumption, improving occupant comfort while also making a positive environmental impact.

What is a sandwich panel?

They are symbolized by a unique finishing material that is applied in multiple layers simultaneously. Panels can be utilized both inside and outside the building. Durable, wear-resistant materials are used to create products for exterior home decoration, and they also include insulation.

Hard, profiled material is used to represent the panels’ outer layer. It offers the house defense against mechanical harm. There is a heat-insulating layer in the middle that is made of mineral wool or other comparable materials. The panels are coated, either smooth or ribbed, with a robust layer of protection from the inside.

Pressing—which can be done with cold or hot pressure—connects all of the sheets. Additionally, environmentally friendly adhesive materials are used. Sandwich panels are an easy and quick building material to work with, making it a great option for individuals with disabilities. At the same time, a strong, lovely, cozy, and secure place to live will be acquired.

Kinds

A multitude of materials can be used to create external sandwich panels. Aluminum or steel can be utilized for this. Polystyrene foam or mineral wool are used as insulation.

The materials used in the production process determine the cost of the panels.

Metal multi -layer panels

These panels are made of stainless steel or less expensive materials coated in zinc to form a protective layer. They are available in a variety of colors and come at a reasonable price. Among their favorable parameters are:

• attractive appearance;
• ease of care for the resulting coating;
• long life;
• low price.

However, these panels have a few major disadvantages. These include low strength, the formation of dark spots after several years of use, and the material burning out quickly when exposed to UV light.

Aluminum sandwich panels

They are occasionally employed in the fast-vested building industry, where a panel-sheathed frame is constructed. This is because there are a lot of good qualities present. Aluminum is utilized in the fabrication of these panels, and it is not susceptible to corrosion. Typically, it is mixed with silicon, magnesium, manganese, and zinc. Panels with the following benefits are the end result:

• resistance before fire;
• stability before mechanical influences;
• the long service life exceeding 30 years;
• the presence of a polymer coating with not only an attractive look, but also resistance before corrosion;
• Environmentally friendly and safe components are used to create the material;
• You can use such a coating even at excessively low or high temperatures.

However, even these materials have certain drawbacks. Among these are the fact that rust may develop on the polymer layer due to easy damage. The coating ages and becomes less visually appealing due to the ongoing effects of the environment.

The intricate processes of installation and transportation carry a risk of damaging the external decorative coating.

Multilayer panels of wood-polymer plates

Use of frame technology, which involves the use of wood-polymer plate panels, is advised if a building needs to be constructed quickly. You can create an internal partition or close off a portion of the wall with their assistance. As a result, sandwich panel buildings can be constructed quickly.

Foam or polyurethane foam are used as insulations when making these materials. The electrical wiring can be readily laid inside the stove.

Because elements are lightweight, they can be used even with a light strip foundation. However, their appearances are not that appealing, so you will need to spend time and effort decorating them. It’s critical to continuously shield wood from the damaging effects of the environment, including antiseptics and pirenoids. You can improve the walls’ thermal insulation characteristics by using premium materials to build an outer layer. Sandwich panel facade repair is an easy process because any component can be disassembled and replaced at any time.

Differences in the insulation

The panels vary in terms of insulation in addition to their outer layer. Different thermal insulation materials with varying costs, thermal conductivities, and service lives are used by manufacturers.

Foam polystyrene

It is a well-liked heater that is used to make sandwich panels as well as insulation for walls, roofs, and other building components. In the latter case, the material has to be protected from moisture, which is why Isospan films are perfect.

Panels and sheets are the two common forms of insulation sold. Using sandwich panels made of polystyrene foam has the following benefits:

• low thermal conductivity, which allows saving on heating;
• good soundproofing parameters;
• small mass;
• inertia, due to which the insulation is not damaged by mold, insects or fungi, although it is easily destroyed by rodents;
• Polistyle foam does not absorb moisture and easily cope with a change in temperature;
• Installation can be performed at any time of the year;
• The life of the material exceeds 50 years.

Polystyrene foam panels have a number of drawbacks, including the material’s tendency to trigger allergic reactions and its prohibition against exposure to sunlight. It is risky to use it for residential buildings if anti-pires are not installed beforehand to prevent fires.

Mineral wool

This type of thermal insulation keeps buildings warm. It is made of natural and safe materials, has good soundproofing qualities, and low heat conductivity. Cotton wool doesn’t burn or cause corrosion to appear in metal components that come into contact with the insulation.

However, because mineral wool is a hygroscopic material, you must firmly attach the panels to the house while sealing the joints with a hydrophobic sealer when decorating the facade. Because mineral wool panels are excessively heavy on their own, they should only be used as a strong base. Installation is only possible in favorable, dry weather. Because fibers break easily, the material’s high parameters are lost.

Methods of installation on the facade

The installation of sandwich panels intended for facade decoration varies as well. A variety of technologies are available for use with corrugated board panels. These technologies include vertical styling, where the panel mounting starts from any corner of the structure, and horizontal styling, which is done from the bottom edge of the wall.

Furthermore, ready-made factory panels are utilized in the implementation of a traditional technology. The ventilation facade is typically formed for the basic assembly, which consists of three layers that are gathered alternately directly on the wall.

Classical

Homeowners who wish to close on a property quickly are more likely to select this technology. Prefabricated facade panels are certified after passing inspections and testing. They can be installed on any type of house and are appropriate for exterior slopes.

The installation is broken up into phases if a classic layout is chosen:

• preparation of the facade cleansing of the old cladding, cracks or dirt;
• House coverage with antiseptics;
• applying a deep penetration;
• installation of the frame;
• fastening of sandwich panels;
• Fixation of inhibits providing the creation of a sealed coating.

Sandwich panels can also be equipped with anti-vandal roller shutters, which guarantee a greater level of resistance to adverse impacts for the products. They are typically found on public infrastructure.

Elepenstate assembly

This technology is only used by experts because it is thought to be highly complex. In order to do this, steps are taken:

• Profile and metal cassettes are purchased;
• A heater is selected, which will be closed on both sides;
• the base is prepared;
• a primer containing antiseptic additives is applied;
• the frame is mounted;
• the first layer of metal cassettes is fixed;
• The insulation is attached, and the presence of gaps or overflow is not allowed, so an even layer is made;
• Another layer of metal is fixed, which performs not only a protective, but also a decorative function.

You must be extremely careful when purchasing the components needed for panel assembly if you want the ideal outcome.

Application on the elements of the facade

Sandwich panels can be used to decorate the facade in addition to being used to build walls and partitions. They are applied to angles, even unreachable places, and even smooth walls. You will need to use a circulation slab to cut the elements in order to accomplish this. To shield the insulation from harm, the cut edge is hermetically sealed with a metal sheet or other materials.

Using metal fasteners included in the kit, the panels are secured with a VSTOK. The installation and alignment of the starting bar require special attention and will need to be guided by future work.

Advantages and disadvantages

Using sandwich panels for facades has the following benefits:

• the efficiency of the sheathing;
• high thermal insulation and soundproofing properties;
• lack of serious load on the foundation and bearing walls;
• long service life;
• An attractive appearance.

However, there are certain drawbacks to using this material. Among them is the fact that attaching a staircase or any other heavy object to a finish like this will not work. Joints must be carefully sealed to prevent condensate from forming and deteriorating the properties of thermal insulation.

Manufacturers and prices

Sandwich panels can range in price amongst different companies. It is contingent upon the intricacy of the manufacturing procedure and the caliber of the components employed. For instance, the cost of panels rises if a fire-resistant heater made of PIR foamyazocyanurate is utilized. renowned producers consist of:

• Stalsoyuz offers panels at a price of 1139 rubles. per 1 sq. m.;
• Klimpanel LLC has been selling panels for 11 years, and the price depends on the thickness of the metal layer and the heater used, but the prices start from 1109 rubles. for sq. m.;
• The Stalnoff plant has been using a flexible pricing policy, selling a sandwich panel for more than 10 years, and the most affordable panels cost from 900 rubles. per 1 sq. m.;
• Vectra plant offers material for 817 rubles. for sq. m.

You should consider an option’s cost, quality, and composition before purchasing it.

The cost of building a whole house from panels

The building’s size, number of stories, layout complexity, and cost of finishing materials are some of the variables that influence this indicator.

A typical project requiring up to 100 kV at home or elsewhere will need roughly one million. 750.000 rubles. The cost may rise to 5.5 million rubles if a custom project is completed, pricey materials are used, and the house is 300 kV. m. in size.
