Types and characteristics

It’s important to comprehend the types and characteristics of materials when it comes to construction and renovation projects. Making decisions that affect the built environment’s usability, durability, and aesthetic appeal is made easier with the use of this knowledge. In this post, we explore different kinds of building materials, paying special attention to their special qualities and uses.

The selection of building materials is a fundamental consideration in the construction process. Different types of materials have unique qualities that suit them for different uses. In order to attain the intended result, builders and designers must consider a variety of factors, including structural integrity and aesthetic appeal.

For example, bricks are a versatile material that is frequently used in construction. They come in a variety of forms, from standard clay bricks to specialized facing bricks intended to improve aesthetics. Knowing these differences makes it easier to choose the appropriate brick type for a variety of uses, including decorative, load-bearing, and facade applications.

The variety of materials used for interior finishes is another important factor. Different flooring materials, including hardwood, tile, laminate, and vinyl, offer varying degrees of durability, upkeep, and visual appeal. Similar differences exist in how long wall finishes like paint, wallpaper, and paneling last while improving the interior space.

Environmental factors are just as important in material selection as structural and aesthetic considerations. Sustainable building methods give preference to long-lasting, eco-friendly, and energy-efficient building materials. This method lowers the environmental impact while also improving occupant comfort and long-term cost savings.

Types	Characteristics
Concrete	Durable and versatile material used for foundations and structures.
Wood	Natural material with warmth and aesthetic appeal, suitable for framing and finishing.
Steel	Strong and resilient material ideal for structural support and framing.
Brick	Durable and fire-resistant material used for walls and facades.

Technical properties

The operational characteristics of panel products are determined by their technical attributes, which align with the declared indicators provided by both domestic and foreign manufacturers.

Compound

The following elements make up wall sandwich panels:

1. Core. It is made from polystyrene foam, polyurethane foam, mineral wool and other types of foam plastics. It is represented by a heat-insulating element and is considered the internal part of the product.
2. Two sheathing sheets made of metal. They are always located on both sides of the core. Sheets provide protection from external damage and moisture.

Some customers form the insulation layer in production according to individual orders for sandwich panels with profiled galvanized sheets, the coating of which is made on the basis of Polyester-type polymers. The layer becomes denser the more insulation is applied.

The regulations from the published TU 5284-001-18201124-2016 and TU 5284-001-62357959-2010 are applied in the manufacturing of any sandwich panel.

The panels’ inner and outer sections are adhered to one another using premium glue, like "DOW."

The table displays the joint venture’s composition:

Environmental friendliness

Sandwich panels are made entirely of natural materials, are impregnated with antifungal and disinfectant agents, and do not trigger allergies, making their material environmentally friendly. Because of the "breathable" walls, the space has a favorable microclimate.

Frost resistance

With a thermal conductivity of λ = 0.05 W/Mk and good thermal insulation properties, the panels are thought to be robust and frost-resistant. Depending on the thickness, this number could go up to 250 (mm).

Degree of sound insulation and fire resistance

Items In compliance with GOST 30247.0-94, they also feature good fire resistance from EI 30 to 150 (belonging to the "NG" group, which is considered non-flammable), as well as good noise and sound insulation (between 30 and 43 dB).

Density

All panel types have a density of 120–140 kg/m3 at any thickness. Although the panels are water-repellent, they absorb 1.5% of their surrounding water content in a day, just like any other natural material.

Dimensions

Sandwich panels are typically classified as wall or roof panels and range in length from 2,000 to 13,500 mm. The widths of the wall ones are 1,000 and 1,200 mm. These two products are variations of this kind. There are 1,000 mm widths for roofing ones.

This article provides more detailed information about the joint venture’s size.

Weight and load-bearing capacity

Sandwich panels weigh 9.2–38.5 kg per m2 for walls and 12.2-43.5 kg per m2 for roofing. The product weighs more the thicker it is.

Furthermore, sandwich panels have a tremendous load capacity (kgf/m2) that is solely dependent on the range of sizes of the panel’s thickness, length, and width in addition to the range of sizes of its supports and spans.

This denotes a high load-bearing capacity, which can change based on the dimensions and type of filler. For all panels combined, the average is 426 kgf/m2.

Service life of joint ventures and buildings

Panels have a limited service life, which is determined by the production parameters, raw material quality, superior packaging, adherence to final product storage regulations, and continued use. Additionally, the anti-corrosion coating and seam width play a major role in how long a product lasts.

The structure has a 25-year lifespan if the front is covered in galvanized material. The warranty on particle boards is for fifty years. Polyurethane filler produces long-lasting products. Constructed homes will have warranties that last longer than 20 years.

It is essential to comprehend the various kinds and attributes of building materials and methods when it comes to construction and renovation. Every variety, including wall coverings, roofing, and flooring, has special qualities that influence practicality, longevity, and appearance. This article will walk you through the types and qualities that are essential to know so that you can make well-informed decisions for your projects.

Types of sandwich panels

The type of insulation used directly affects how wall panels are categorized. The most widely used materials include fiberglass with a combination of filler and polyisocyanurate foam, as well as polystyrene, polyurethane, and mineral wool products. They can be used in both residential and commercial buildings because they are all lightweight and have excellent insulating qualities.

The filler types listed below are used to make steel galvanized slabs. It is between 0.5 and 0.7 mm thick. Additionally, there are models made of plastic. By functional purpose, all products are separated into:

1. Industrial wall. Made from absolutely any insulation and cladding (plastic, metal). Have a layer thickness of 50–200 (mm). Attached to any frame used during installation – metal (aluminum), wood.
2. External roofing. Very durable. Made only from metal cladding (high-quality profile). Mineral wool or polyurethane is used as internal filler. Has a thickness of 40-200 (mm).
3. Walls for residential buildings. The cladding layers are often made of OSB. The inner part is often polystyrene foam, lightweight, with a thickness of 60-200 (mm).

Sandwich wall panels work well for low-rise buildings’ exterior walls. They can be used as housing or to design small offices and other spaces.

However, sandwich panels are particularly well-liked for setting up ceiling walls and partitions for roofing.

The following types of SP are differentiated based on the type of polymer coating:

• polyester – glossy and matte;
• plastisol – suitable for external and internal structures;
• polydifluorionade – due to their good thickness, they are practically not subject to mechanical damage;
• pural – matte silky, UV resistant, therefore used for external walls.

Panels with different locking connection types are used to categorize products.

• tongue-and-groove (tongue-and-groove connector);
• secret fastening "Secret-Fix";
• double Z-Lock shutter;
• roofing "Roof-Lock";
• rebate lock.

Speak with a construction specialist to determine the best connector type for your particular situation, as they will consider factors like the direction in which the slabs are installed and their intended use (roofing, partitions, fencing).

By type of insulation

Let’s examine the various panel types in more detail according to the insulation type.

Expanded polystyrene

The panels are resistant to chemical and biological irritants and have excellent thermal insulation properties. This kind is lightweight (two times less than mineral wool), water-repellent, temperature-independent, and non-flammable in addition to providing good protection against background sounds and noises.

Along with these benefits, the material is also resistant to deterioration over time, durable, and has good adhesion to a variety of substances. Sandwich panels made of expanded polystyrene are a sturdy and dependable material that is appropriate for use in the winter.

The panels’ sensitivity to UV rays, shrinkage at excessive temperatures (above 1000°C), and potential for rodent damage are their drawbacks.

Polyurethane foam

Fine porosity is one of the properties of the polyurethane foam (PPU) filling used in these products. They are thought to be chemically neutral for aggressive alkaline substances, have a low level of thermal conductivity (good for outfitting rooms with refrigerators), and are not easily deformed by external factors like mechanical stress or fluctuations in the atmosphere.

The material’s durability, elasticity, safety in the environment, and resistance to mold and fungus are further benefits. Additionally, he works well with all materials (metal, plastic, and wood).

PPU sandwich panels have two drawbacks: they are relatively expensive and have a higher flammability due to their easily combustible materials.

Mineral wool

The model on display is constructed with mineral wool, an eco-friendly material, for internal insulation. The internal structure of the product is fibrous as a result of the utilization of naturally occurring silicate alloys (slag, rocks).

The non-flammability, mold and fungal microbe resistance, high protection against noise and sound absorption, lack of tendency to shrink and deform due to temperature changes, and ease of installation are the benefits of using mineral wool sandwich panels.

The material’s high water absorption and vapor permeability (which necessitates extra caution and protection from water during production), large mass (which adds to the base’s load when forming walls), and the fact that it should only be used during the dry season are thought to be its drawbacks.

Fiberglass

Although the technology used in the production of fiberglass sandwich panels is somewhat different from that of mineral wool, the long fiber length and thickness are still present. The material’s resistance to chemically reactive substances and the inner layer of the panel’s strength and elasticity are its primary advantages.

Furthermore, fiberglass sandwich panels are non-flammable materials that are thought to be lighter than other materials, like mineral wool. Among the benefits are their excellent resistance to mechanical vibration, superior noise insulation, good thermal insulation, and environmental friendliness.

The high water absorption qualities, caking ability, temperature sensitivity, and weathering ability of panels made with this filler are thought to be their drawbacks.

Polyisocyanurate foam

The material that is being presented is the best blend of polyurethane foam and specific additives to enhance its properties and produce a flame-resistant layer for use as a thermal insulation layer in sandwich panels.

Polymer materials with low heat conductivity, high elasticity, resistance to mechanical and atmospheric vibrations, and environmental friendliness are referred to as polyisocyanurate foam.

The material also has good adhesive qualities when interacting with other materials (glass, concrete, brick, and so on), resistance to fungi, mold, and water, and high strength, which enables you to save money on metal structures. Penopolyazocyanurate is regarded as a long-lasting substance.

Some of the disadvantages associated with the plates of this type are that they are more susceptible to UV radiation, precipitation (hail, rain, and snow), and high cost.

Our material contains more information about the joint venture with fenopolyazocyanurate.

Combined

Sandwich panel fillers of this kind include goods with layers of polystyrene foam and mineral wool at their core. High fire resistance, strength, dependable thermal insulation, and noise and sound protection are all provided by this combination. The only drawbacks to such a product are a few exaggerated costs.

By type of cladding

It is also important to note that sandwich panels are classified into the following categories based on the type of cladding they are used with:

1. Plasterboard, fiberboard, plywood, fiberboard. The presented types get their name from the material with which they are lined. The peculiarity of the panels is that they have the same cladding on only one side (inner). The outer (outer) side is most often made of a metal profile. For example, a DSP panel is made from a mixture of cement and shavings on one side, and from a thin metal profile on the other. An important advantage of these types is the convenience of arranging communications (for example, wiring).
2. Metal. The presented views from the outside are completely sheathed with a galvanized or stainless steel thin layer of rolled metal, on top necessarily coated with polymer from the manufacturer (pural, polyester, plastisol, etc. d). Products have a smooth surface or are presented in the form of microwaves, for example, in the production of roofing slabs.
3. PVC. Here, polyvinyl chloride sheets with a rigid structure were used outside. Such sandwich panels are especially in demand for arranging partitions, window and door openings, or their slopes. Inside, the core is most often represented by extruded polystyrene foam.
4. Paper. Such products combine butamized compressed paper and aluminum foil that reflects infrared radiation, rarely polyethylene. They are good as thermal insulation for any premises that require additional insulation, so they are often made with a mineral wool core. Due to the fact that foil or polyethylene do not allow steam to pass through, they do not accumulate condensation, therefore they are suitable as the inner layer of warehouses. They are relatively lightweight compared to other types, so they are considered quite ergonomic.
5. Woody. This type can be made from high-quality wood or any wood material or substance “like wood”. Such panels have different shades in their color scheme, which is very aesthetically pleasing for exterior decoration. Sandwich panels have low cost, good thermal insulation and a “breathable”, environmentally friendly layer, increased tightness, and are easy to install.

For these panels, there are additional decorative coating options, such as: h. beneath brick, stone, etc. d.

The right choice of products for construction

It is advisable to choose products with future operations and parameters in mind. This is a crucial point to remember because different sandwich panels work better in different situations. Here, the filler is also very important.

For instance, polyurethane products work best in rooms where refrigerators will be used. And sandwich panels with mineral wool are used for buildings where fire safety is a concern.

When selecting items, keep the following in mind:

• method of foaming used insulation (uniformity of composition and pores matters);
• assembly of individual elements (appearance, presence of grooves, structural integrity);
• certification and documentation from the manufacturer (availability of a guarantee, instructions, accompanying papers confirming the construction nomenclature and workmanship);
• integrity of the packaging (polyethylene from the manufacturer, indicating the product labeling, must be intact);
• storage conditions (it is not recommended to purchase panels in very damp rooms, as this indicates a violation of storage conditions).

You should select the sandwich panel’s parameters at the same time. For walls, for instance, it is best to select models with widths between 1 and 1.5 (m) and lengths between 2 and 19 (m). Panels with a width of 1 (m) and a length of 1-16 (m) are appropriate for the roof.

The preferences for the interior microclimate determine the panel thickness. The room will be warmer and the cost of heating will be lower in the thicker the product.
