Facade sandwich panels

The efficiency and adaptability of facade sandwich panels have completely changed the exterior design of contemporary buildings. Two layers of material are fused to a core material, usually insulation, to form these panels. There are a lot of aesthetic options available when it comes to the outer layers because they can be made of different materials like wood, fiberglass, or even metal.

Sandwich panels for facades have a number of benefits, one of which is their high structural strength and lightweight design. Compared to conventional cladding materials, this makes them simpler to install and lessens the strain on the building’s framework. The superior thermal and acoustic qualities of the insulation core also improve the building’s interior comfort and energy efficiency.

Sandwich panels for facades are preferred by builders and architects due to their weather resistance and longevity. Their durability and functionality are ensured by their ability to tolerate inclement weather, wind, and temperature changes. Their longevity results in reduced maintenance expenses and an extended lifespan, rendering them an eco-friendly option for contemporary building.

First meeting

Device

Originally referring to a multi-layer sandwich, the term "sandwich" eventually extended to all multi-layer constructions.A facade panel is composed of what layers?

• The outer and inner layers are a rigid material that protects the insulation from mechanical damage and the rigidity of the structure as a whole. In most cases, metal – aluminum or galvanized steel acts as an external coating. However, the use of polyvinyl chloride or magnesite slab is also practiced.
• Inside, respectively, is a layer of insulation. The panel is assembled on glue by cold or hot pressing.

The figure represents a particular kind of sandwich panel.

Story

For the first time, sandwich panels were used by American engineer Frank Wright in 1930. The material was far from perfect; However, installation was significantly facilitated in comparison with the then existing systems of insulation. The main goal was achieved. The first mass production began in 1959, when Koppers rebuilt its lines to produce cars for a new, more promising project. Literally a year later, ALSIDE pulled up, which polished production technology and reduced the manufacturing time of panels. In the Soviet Union, its own production began in 1974 at the capacities of the Samara plant electrical panel. The polyurethane foam acted in the role of insulation, the outer layers of the panels were metal. Kamaz and Volgodon atommas pulled up a little later.
Panels of domestic production found application primarily in industrial construction.

Used insulation

What kind of insulation can be built into a sandwich panel facade?Let’s examine every material that was used.

• Mineral wool is valuable primarily because it does not support combustion. Basalt wool, in addition, practically does not cake; That is why most often as a filler and insulation for the panel, it is it that is used.
• Polyurethane foam is convenient in that it can be used in high humidity conditions. Facade sandwich panel of two sheets of aluminum and foamed polyurethane heater can be immersed in water for an unlimited time; In this case, high humidity will not lead to the appearance of mold or fungus – the insulation is not a nutrient medium for them. In addition, polyurethane foam – material is quite tough. The panels will be more durable: the insulation itself acts as an additional strengthening.

The strength of sandwich panel walls is increased by the rigidity of polyurethane foam.

Polistyle foam is significantly less expensive and, crucially, slightly lighter than the prior substance. This is an excellent material for insulating cold storage facilities and other commercial buildings; however, polystyrene foam is used somewhat less frequently for insulating building facades.

Foam polystyrene fuel: Its use may be discouraged by strict fire safety regulations.

Types of coating

Sandwich panel facades vary not only in terms of warmth but also in terms of internal and external coating.What choices do we have in the market?

The least expensive and most resilient material is galvanized steel. Zinc protects against corrosion. But steel is a heavy material, which frequently goes against the goal of using panels to create the lightest possible facade.

Galled steel is reasonably priced and strong at the same time. It is the most widely used material for the panels’ outer layer for this reason.

• Aluminum. Light material; However, its mechanical strength somewhat loses to the previous option.
• Alucinki – aluminum and zinc alloy with silicon addition.
• Plazor – in essence, ordinary polyvinyl chloride with plasticizers. The material is light and strong enough to suit the facade decoration.
• Polyester is another plastic that has a fibrous structure and high mechanical strength. If PVC needs special supplements to protect against ultraviolet radiation, then polyester does not burn out in principle.

Kinds

The cladding and insulation materials used for exterior house decoration vary, as does the installation technique for facade sandwich panels:

Differences on the material of the cladding

A crucial component of the panel in charge of strength and appearance is:

Metal multi -layer panels

Possess a corrugated, smooth surface. Cladding is done with galled sheets that range in thickness from 0.7 to 1.2 mm. Steel that has been galvanized resists rust and does not grow fungus. The panel endures several cycles of frost-breaking cycles without being damaged by precipitation.

Excellent anti-vandal qualities and resistance to mechanical exposure characterize galvanized metal. You can precisely select the panel color for a given set of circumstances with the polymer coating found in the RAL and RR catalogs.

The element’s weight is its drawback. A sturdy foundation or frame is required for the installation of metal sandwich panels.

Aluminum sandwich panels

A more costly choice for cladding. Metal panels weigh a lot more than aluminum ones. It costs a lot more per square meter. Their strength and anti-vandalism features are listed below. The elements can be sheathed with shaky, outdated emergency bases because of their low weight.

Sandwiches made of aluminum can withstand the harsh effects of atmospheric precipitation with perfect ease. Seasonal variations in temperature do not destroy them.

They are unclaimed in private construction due to their high cost. Production and commercial buildings are completed with their assistance.

Multilayer panels of wood-polymer plates

Frame low-rise residential buildings are constructed with SIP panels. Slabs of wood are a pure, safe material. Their strength is more than sufficient to arrange the cottage’s exterior walls. You can lower the cost of the reinforced concrete foundation device by using a small weight.

Differences in the insulation

A crucial part of the panel that controls noise reduction and thermal insulation. Two varieties of insulation are utilized in the creation of sandwich panels:

Foam polystyrene

Simple and trustworthy. Moisture cannot pass through foam or be absorbed. He has good noise sounding indicators and a low heat conductivity coefficient. Sandwich panels made of foam can be installed below ground.

Foam multilayer facade components don’t always adhere to fire safety regulations. Industrial and non-residential buildings are covered with them.

Mineral wool

A stronger layer of insulation. Basalt mineral wool with a higher fiber density is used to make panels. Because mineral wool absorbs moisture, it requires extra protection. She exhibits high sound insulation indicators and low thermal conductivity.

Mineral wool meets all requirements for fire safety. It can be incorporated into panels to adorn both public and private structures.

Differences by installation method

Sandwich facade finishes are applied in two different methods:

Classical

Factory-cut finished panels are used to sheathe the walls. The castle is joined by plates. mounted either on the frame or a nude base. Starting with the bottom corner, install the system. Use specialized mounting foam or silicone sealant to sandwich panels next to one another.

Elepenstate assembly

Layers cover the walls or frame. Low-rise frame structures are being constructed in this manner. Aluminum or galvanized steel cassette panels are affixed as the top layer. You put mineral wool inside of them. Over that, a second metal cladding layer sheaths the structure. Every seam that separates the components is completely sealed.

Sandwich panels coating

The modern sandwich panel device uses a variety of fillers and coatings for insulation. The following materials can be used to create sandwich-style panels:

• galvanized steel is distinguished among analogues by ease of operation, significant anti -corrosion properties; The thicker the layer of zinc, the longer the panel lasts;
• alucinc (as part of aluminum + zinc + silicon)-reflects UV radiation, permissible temperature mode of use-up to + 315 ° C;
• drywall (on the sides construction cardboard, inside a gypsum core) – small weight, environmental safety, suitability for residential premises;
• playsol (PVC with plasticizers) – has a high density, the material is recommended for use in difficult weather conditions, is not afraid of mechanical damage, meets the requirements of internal and external decoration of the premises;
• Orlit is moisture -resistant (wood in the form of chips + glue) – reliable protection against moisture, which is affected by the quality of the glue;
• OSP is a wooden chip glued under pressure;
• Pural (polyurethane + polyamide) – suitable for external and interior decoration, protects from unstable temperatures and sharp differences, burnout, corrosion;
• polyester – withstands a long high -temperature regime, does not burn out, resistant to mechanical damage;
• Polypropylene/polystyrene finish window openings (sandwich-pinks).

Installation instructions

We would like to draw your attention to the following brief instructions for installing sandwich panels. Building the foundation and frame is the first step in building a house out of sandwich panels. The distances between the panels’ dimensions and the frame’s vertical and horizontal profiles should match. The frame’s rails are all precisely exhibited. A lot of people are curious about how to mount a lining by hand. Typically, provide joints and a five-centimeter indentation from the edges.

Using an antiseptic and a corrosion method, the surface is cleared of dust and debris during the preparatory stage. Choose the installation tool:

• for a wooden frame-wood screws for sandwich panels;
• for reinforced concrete foundations – anchors and dowels;
• The metal frame requires self -driving screws (the holes should be smaller in diameter in the supports so that reliable fixation is obtained).

A screwdriver with an 8 mm hexagonal magnetic nozzle will also be needed for facing work. It might be necessary to alter the standard sizes when installing facing elements. cm table to select the cutting instruments.

Jigsaws: electric and hacksaw

Electrolobzik greatly improves SPIL.

Metal cutting scissors, jigsaw, and circular saw for cold processing

Since the protective layer on steel cannot get too hot, the grinder, grinder, and plasma cutting are not appropriate.

SIPs, or structurally improved plates

Circular electric saw using a hand tool

Ensuring the edge’s integrity and even connection is crucial. An electrician is not the right person for this task.

How to prepare wall canvases for installation: important points of installation

Prior to beginning any installation work, it is first required to remove the protective film that the manufacturer had applied to each sandwich panel’s surface. Helpful tip: make wood or foam gaskets ahead of time before laying out wall canvases to prevent scratches on the building materials’ anti-corrosion coating. Visually inspect the cladding’s castle sections to make sure the insulation does not protrude (if needed, a wooden scraper can help you carefully remove any excess).

Second, all of the panels—particularly the first one—should be perfectly level. The appearance and caliber of thermal insulation will be seriously harmed if you make a mistake because the error of deviation from the horizon will grow with each additional structural element. After every third wall canvas is installed, control by level is completed.

The third crucial point is that the control wishes’ marking will aid in observing the size’s accuracy. Subsequently, all vertical joints are sealed with tinkers and filled with mineral wool after the panels are installed. The mounting nodes are also waterproofed. Shaped pieces fastened to screws or rivets conceal the seams.

We would like to remind you to take safety precautions. The contractor needs to wear a respirator when working with mineral wool. To prevent the filler from swelling, it is not advisable to install structures made of mineral wool in high humidity conditions. After installation, protect the sandwich panel exterior coating from mechanical forces by avoiding leaning against stairway facades, supports, or construction machinery. Scratches can be painted with specialized repair dyes, and conventional contaminants can be removed with a soft brush and soap.

Wall Sentifier panels: sizes and prices of panels

Walls and partitions are constructed with wall sandwich panels. Depending on the materials used to make the plate, there are differences in the Sentifier panel sizes and prices. For instance, 50 mm thick PPU plates or products with an internal mineral layer of 100 mm are required to achieve the same level of thermal insulation for the home.

Wall sensor finger standard size, N = 50, 80, 100, 120, 150, 200, or 250 mm

Products with lengths of 7.5-8 and widths of 1.15 m are used for the installation of industrial structures. You can expedite and streamline the building’s installation process by utilizing long panels.

The standard sheet measures between 3 and 8 meters in length, 1.2 meters in width, and 40 to 320 millimeters in thickness.

One drawback of sandwich panels for walls is that they are not very resistant to mechanical forces. Special protective compositions are applied to sheets to improve strength indicators. A wide assortment makes selecting and purchasing a solar panel simple. The following table shows the cost of various wall plate types (per 1 m2):

Type of wall panel	Filler	The price of the panel, depending on the thickness, rub./m²

Price and sizes of sandwich panels for roofing

Because these plates are made in tandem with the insulation, their popularity during roof installation is determined by this. As a result, the roof structure’s construction takes a lot less time. The most popular material used to create these panels is galvanized steel coated in a unique protective layer. Second on the list is stainless steel. The roofing sandwich panels have the following measurements: length 8–16 m, width 1000 mm, and thickness 40–160 mm.

You have the option to place an individual order if necessary, as many companies produce products with non-standard sizes. The thickness, kind, and manufacturing material of insulation all affect how much roofing panels cost. The following table shows the approximate costs for one square meter of different roofing plates:

Type of roofing panel	Filler	The price of the panel, depending on the thickness, rub./m²
Panel thickness, mm
40	60	80	100	120

Basalt cotton wool	–	2380–4550	2440–4600	2510–4670	2580–4750

Any kind of Sentifier panel can be purchased from a specialty shop or hypermarket dedicated to building supplies. Additionally, you can use the Internet to order the required building supplies.

Vertical or horizontal installation?

You must have a firm grasp of installation technology if you’re looking for instructions on how to construct a house out of sandwich panels. It can be installed vertically or horizontally. Select an installation technology, making sure to follow these guidelines: A vertical mount is used for floors between three and six meters in height; for floors higher than six meters, use horizontal skin.

Vertical installation: every panel is uniformly fastened to the ceiling, the metal guide, and each other. If you own a residential building, you will be protected from cracks and frost by having the sealant applied on both sides. The sealant application process is executed while considering the local weather and ambient temperatures. The installation process starts at the building’s corner and moves left to right.

When high floors (above 6 meters) prevent you from raising the budget for the installation of construction forests and a crane challenge, horizontal installation makes sense. With this technology, the wall canvases are arranged according to the "upper panel on the lower" principle, and the installation captures are situated on the frame’s columns. The fastening order is as follows: grooves are positioned below for drainage lightness starting from the bottom up. The frame’s horizontal step shouldn’t be more than six meters.

"Facade sandwich panels offer a versatile and efficient solution for modern building exteriors," could be the main thesis statement for an article on facade sandwich panels on the website "All about the facades of the house." These panels offer good weather resistance and thermal insulation while combining durability and aesthetic appeal. This article explains how these panels are a popular option for architects and homeowners who want to combine style and functionality in their building facades. They also lower maintenance costs and increase building efficiency.

Characteristics and composition of aluminum composite

The well-liked product’s layer sequence is as follows:

• protective coating with anti -corrosion properties;
• The primer for the giving aluminum sandwich panel of resistance to the formation of rust;
• first aluminum sheet up to 0.5 mm thick;
• Plastic layer;
• second aluminum sheet up to 0.5 mm thick;
• A primer layer of a composite based on polyvinylendenfluoride resin;
• varnish composition;
• protective film.

Different aluminum panel thicknesses are available for easy selection based on the tasks involved. Well-known brand products have a non-flammable base.

Advantages and disadvantages

Aluminum sandwich panel advantages include the following:

• ease;
• strength;
• high insulating properties;
• resistance to environmental influences.

This building material is resistant to aggressive deposits, sunlight, wind, high and low temperatures, and atmospheric dust. It also resists precipitation.

They can function as complete fire barriers because they are not ignited.

Aluminum sandwich panel models come in a variety of materials with varying degrees of fire safety. They can function as complete fire barriers because they are not ignited.

Panels can be shaped into a vast array of shapes because of the combination of soft elastic material inside and hard aluminum sheets on the outside. They are bendable, millable, choppable, and drillable.

It is not necessary to mill additional grooves when creating cylindrical, oval, or curved objects from the panels using cold rolling. It is possible to apply a self-adhesive film to this silkscreen-printed material.

One of the drawbacks is that aluminum sandwich panels are more expensive than a lot of other building materials that are used to decorate walls. Modifications are not fire resistant and release harmful substances when they burn because a regular polymer filler is used in their manufacture instead of antipyrene additives.

Special materials are required for thermal insulation.

As a result, their function in wall decoration is limited to decoration. Special materials are required for thermal insulation.

Description

Sandwich panels for facades are multilayered construction materials that include insulation between the exterior and interior protective layers. Between the exterior cladding and the mineral insulation is a layer of vapor barrier. On the one hand, he prevents atmospheric moisture from saturation the porous mineral wool, and on the other, he removes condensate.

Pressing and adhesion are the mechanisms that link insulation and facing material. The following sizes of multi-layer panels are accepted: 3000 x 1150 x 32 mm, 3000 x 1150 x 24 mm, and 3000 x 1150 x 10. The first number represents length, the second, width, and the third, thickness. In order to install interior partitions, more compact panels measuring 1,500 mm in length and 1000 mm in width are made.

Finishing work and conservation of heat

There is a significant benefit even though using sandwich panels requires a lot of particular details. This has a high degree of sound absorption and thermal insulation.

To avoid damaging the construction’s overall structure, their use should be rational and reasonable.

Therefore, a heat engineering calculation has to be done first. The materials that will be used for interior and exterior decoration, as well as the layout of the ventilation system, are unknown to the designer. Panel homes frequently lose their benefits as a result of the insulation’s material being destroyed by the calculated point being displaced. However, if a specific synthetic filler (polyurethane foam, polystyrene foam) is used, this issue can be easily resolved.

And lastly, there’s the matter of ornamental decoration. In most cases, it is not necessary when using SIP panels. Coatings can be used for both wet and dry drying. Nevertheless, extra security for insulation is not required.

Quick -made buildings

Sandwich panel buildings fall into the category of quickly vested buildings.

Non-residential production or administrative buildings are the most common kind of these buildings:

• Warehouses.
• Public premises.
• Sports or fitness centers.
• Auto Show.
• Commercial or entertainment centers.
• Industrial refrigeration chambers.
• Angars for large air equipment.

Crucial! Building structures to house their sandwich panels is becoming more and more common. The low cost, quick construction, and lack of requirement for a strong foundation are becoming more and more alluring to users.

Buildings that are rapidly vested are constructed in accordance with the following standard scheme:

• The construction of a metal frame from unified elements that give a wide combination of assembly options – as if from a children"s designer.
• Installation of sandwich panels. The installation of panels takes a matter of minutes, most of the time is sealing joints and installing additional elements.
• Installation of roofing panels, the design of overhangs and other elements with inputs.
• Design of window and doorways.

Everything is completed very quickly. The construction of the foundation, the cost and type of which are dictated by local geological conditions, accounts for the majority of labor expenses and capital outlays.

Criteria for choosing external facade skin

In order to get cladding that will not only look good but also last a long time, they consider the following factors when making their purchase:

• Cost – the price of the panels themselves, additional elements necessary for a high -quality installation, and the performance of work, if you plan to entrust the entire decoration process to professionals.
• The similarity of imitation with natural material, as well as the quality of the applied decorative layer. Disabilities, streams, bubbles and other flaws are not allowed.
• Linear values ​​of panels. All details in one package and parties should have the same size.
• If the finish has fasteners, then it is checked. Metal parts are clean, without rust, covered with a protective composition, even – when the option is suitable.
• Slas must be operated by the manufacturer.
• Critical temperatures at which panels retain the original attractiveness.
• The presence of a quality certificate.

You are welcome to purchase the appropriate quantity of material if the option you like meets all the requirements. Remember to set aside 10% to 15% of the reserve. If suddenly a few details are revealed, you won’t need to search the nearby stores for the same party.

The main types and characteristics of the material

The market for building materials today provides an enormous assortment of facing materials that vary in:

• the raw materials from which are made;
• installation method;
• imitations of different natural materials;
• sizes and forms of parts;
• The installation site (wall or basement).

However, there are three types of panels that are used to line houses, regardless of how private or apartment buildings are:

1. Single -layer – perfectly protect the facade from the effects of external negative factors. But are not able to maintain heat inside the house. If there is a need for additional thermal insulation, then I use the insulation material, and the single -layer panels close it.
2. Thermal panels and two -layer cladding. Insulation and finishing material are fastened to each other. This option solves two problems at once: facade cladding and insulation.
3. Sandwich panels or three-layer. In this option, the insulation is not only closed by decorative trim, but also covered with hydrophobic membranes, which do not allow moisture to enter the heat insulator, which significantly increases the life of the material.

You shouldn’t choose to purchase the first option you find because the house is subjected to multiple loads. The decision is extremely important.

Sandwich panels for facades are a flexible option for contemporary building exteriors. Their creative design offers superior insulation and structural support by combining layers of materials such as metal, aluminum, or composite materials.

The lightweight design of façade sandwich panels is one of its main benefits as it facilitates handling during installation and lessens the structural load on buildings. Because of this feature, they are perfect for projects involving both new construction and renovations where efficiency and speed are critical.

In addition to their functional advantages, these panels enhance a building’s visual appeal. They are available in a variety of hues, patterns, and sheens, enabling designers and architects to create a broad range of styles, from sleek and modern to textured and traditional.

Furthermore, façade sandwich panels are renowned for being long-lasting and requiring little upkeep. Their resilience to weather, corrosion, and fading guarantees their long-term functionality and visual integrity.

To sum up, façade sandwich panels are a cutting-edge, practical, and visually beautiful option for improving building facades. They are a popular choice in modern architecture and construction because of their unique combination of durability, design flexibility, and functionality.
