Dimensions and cost of sandwich panels

Speed ​​and quality in construction are two seemingly completely different concepts that do not intersect and do not interact in the complex process of building construction. However, modern technologies are breaking the established stereotypes.

Today, the most popular and practical building materials are sandwich panels. They make it possible to implement architectural solutions of varying complexity in record time.

Sandwich panels make the building warm, durable and aesthetically pleasing. There are different types and purposes: it all depends on the heat-insulating insulation and the material from which the framing sheets are made.

There are wall and roofing. When choosing a material, you need to know what is the difference, what is their operational feature and what is their advantage? How not to get lost in a wide range of manufacturers and follow the path of least resistance?

Dimensions and weight

The dimensions of the sandwich panels are standard:

1. Length - 1.8 - 13 m.
2. Width - 1.2 m.
3. Thickness - 50-250 mm.

The weight of the material depends on the thickness of the used insulation and cladding sheets. Basalt fiber slabs are the heaviest heat insulators. The reason for this is not only the specific gravity of the insulation itself, but also the fact that to create high quality sandwich panels, it is necessary to use at least 80 cm of mineral wool.

Calculating weight sandwich panels, the density of the insulation is taken into account. Therefore, mineral wool has the highest density - 110 kg per cubic meter, and the smallest - expanded polystyrene, with a density of 25 kg per cubic meter. To calculate the total weight, you need to know the mass of the cladding sheets, the thickness of the insulation layer and the dimensions of the panel itself.

Sandwich panels with a thickness of 50 mm based on mineral wool and galvanized sheets weigh 15.2 kg, with a thickness of 200 mm - 38.2 kg. With 50 mm expanded polystyrene, the panel weighs 9.8 kg, with 200 mm - 14.8 kg. With polyurethane foam of 50 mm, the weight reaches 11.2 kg, with 200 mm - 22 kg.

Price, advantages and disadvantages

The cost of a building material depends on its purpose, thickness and insulation used.

Prices for facade sandwich panels with mineral wool start at 800 rubles per square meter. They can reach 1,500 rubles, depending on the color and amount of the heat insulator.

Wall panels have a cost in the range of 1100-2150 rubles.

Main advantages:

1. Fast installation speed, easy maintenance and repair.
2. Construction does not require special conditions, it can be carried out at any time of the year.
3. Keeps the room warm effectively.
4. Created from environmentally friendly ingredients, easy to care for and safe for human health.
5. Being lightweight, they do not unduly affect the foundation.
6. Installed without additional external finishing.
7. According to sanitary standards, they can be used in the food industry and for the construction of medical institutions.
8. Does not react with chemicals and aggressive natural conditions.
9. Quite low cost in comparison with wood, brick, concrete panels.

Main disadvantages:

1. May not withstand strong mechanical stress.
2. External damage often appears in the form of chips and scratches.
3. At the joints between the panels, gaps are formed through which cold air can penetrate.
4. Freezing is possible for the same reason.
5. The frame can be damaged due to strong condensation and dew point.
6. Over the years, the panels dry out and decrease in volume, which is why they lose their performance.
7. SIP panels can release toxic formaldehyde.

Description and scope

Sandwich panels Is a material that consists of two rigid sheets and insulation that meets various requirements. The main purpose is housing construction for the creation of pre-fabricated buildings. Such panels are called with the SIP or SIP prefix.

They have a hermetically sealed structure. The basis for such panels is OSB boards with polystyrene foam interlayer. Its cost also depends on the thickness of such a panel.

For commercial purposes, they are used in the construction of supermarkets, shopping centers, sports complexes, industrial workshops.

You may have noticed more than once how tall car dealerships, new car washes and huge sales areas appear before our eyes. This is the construction technology with the use of sandwich panels.

For the first time, the material was produced in the USA for the construction of a one-story building. Initially, the technology had more disadvantages than advantages, however, the panels looked very attractive and were easy to use.

Over time, the construction process has been improved and brought to the level of mass consumption. In Russia, the material found its use in 1974. Not much time has passed, and the percentage of distribution in the market has reached 40.

They are used for the implementation of such projects:

1. Trade and sports pavilions.
2. Constructions for shops and fast food.
3. Warehouse and industrial buildings.
4. Agricultural buildings.
5. As interoffice partitions.
6. For roof installation.
7. For cladding buildings ..

Sandwich panels provide high-quality insulation and can be used as a material for building renovation. In the future, the production of panels that could independently generate electricity is being considered. For this, photocells are built into the structure of the sandwich.

Varieties

Sandwich panels differ depending on the insulation used.

The following materials are used:

Styrofoam or Styrofoam

It has a cellular structure. Sandwich panels with a similar insulation are relevant in the production of industrial facilities, retail outlets and storage chambers. It is also used in the recently popular "Canadian technology", which allows you to create homes quickly and reliably.

Pressed mineral wool

Popular and demanded material. Mineral wool panels are used in the construction of simple structures where speed and simplicity are important.

They are easy to repair, have high thermal insulation qualities and do not burn when exposed to open fire. They easily tolerate low and high temperatures, do not deform, have excellent sound insulation properties. They do not respond to aggressive environmental influences.

Polyurethane foam

It combines very valuable qualities: strength and lightness. Such panels are durable and waterproof. Has high thermal insulation properties.

A distinctive feature of the material is the fact that polyurethane foam is resistant to the appearance of fungi, mold, does not lend itself to attack by rodents and insects. It is fireproof, therefore it has wide industrial and domestic use. The only drawback is the high cost of such panels.

Fiberglass

A material for a specific purpose, which consists of many thin glass threads. In fiberglass panels, soundproofing properties are especially appreciated. It does not burn, it is easy to transport and install without much difficulty. Resistant to chemical attack. However, such panels can only be used in environments where the temperature does not rise above 40 degrees.

Polypropylene

It has a honeycomb structure and is resistant to moisture. Not susceptible to chemicals. It has light weight and low thermal conductivity. Such insulation during the production of sandwich panels must be protected from fire by choosing the right facing material.

Also, the panels may differ depending on the type of coating. The structure can be made of two different cladding materials or have the same origin. The outer coating determines the basic functional properties of the sandwich panels.

There are the most common materials used as cladding:

1. Zinc plated steel - the most popular and affordable material that protects panels from corrosion, has a long service life and is easy to handle.
2. Pvc - relevant for indoor use.
3. OSB - the basis of panels for prefabricated structures.

Properties and characteristics

Main technical characteristics:

1. High strength.
2. Low moisture absorption.
3. Optimum thermal conductivity.
4. Long service life.
5. Resistant to temperature extremes.
6. Ability to resist chemical and weather conditions.
7. The ability to use from -50 to +60 degrees.
8. Withstand pressure of 0.96 MPa.
9. High sound insulation.

Under the press, with the help of loading devices, facing materials and internal insulation between them are placed. The surface is coated with high-strength glue and pressed with a press under pressure.
