Sandwich panel partitions are a clever, practical way to divide spaces in modern buildings. These panels are perfect for both commercial and residential projects because of their superior insulating qualities, lightweight design, and simplicity of installation. Sandwich panels are a quick and cost-effective way for builders to quickly construct thermally regulated and highly soundproof partitions while cutting down on construction time. This article provides clear guidance for anyone thinking about using sandwich panels for their next project by examining the main advantages and useful aspects of using them.

Are sandwich slabs suitable for interior walls??

To divide the interior space, partition structures are required. They are frequently placed in warehouses, offices, production workshops, and shopping malls. Sandwich panels are a useful material for this kind of construction.

These raw materials possess all the essential qualities:

• excellent sound insulation;
• strength;
• durability.

As manufacturers have taken care of a variety of colors, each property owner can select a panel of their choice or combine them.

Since the structures are delivered to the construction site already assembled, partitions made of this type of material are regarded as prefabricated. Employees only need to affix them to the assigned location.

Sandwich panels are also used frequently for internal partitions in shopping centers because of their high fire safety rating due to the mineral wool filler they contain, which does not burn.

Requirements

When using such material for partitions, there are specific requirements. They should have a minimum thickness of 40 mm and a maximum thickness of 250 mm. A non-flammable filler, which frequently serves as insulation, should be present inside.

Panels constructed today using this kind of insulation:

• mineral wool;
• expanded polystyrene;
• polyurethane.

Only mineral wool, out of all the materials mentioned, is classified as non-combustible substances (fire safety class NG).

While some raw materials are also marginally combustible, these materials will eventually catch fire as well.

Panels with aluminum honeycomb inside are frequently utilized to build these kinds of structures. It is also believed that this material is fireproof.

Since the panels will be used in areas with constant human traffic after construction, they must all be certified. Smaller thickness panels are frequently used; this is an option when sound insulation is not a concern.

Design Features

In addition to sandwich boards, other materials are also utilized in the design of the partition:

• metal support frame;
• screws for fastening;
• shaped elements;
• adhesive materials – foam or sealants;
• sealing tape.

If you choose turnkey partition construction, the total cost of the project also includes all of the specified components. In this instance, the panels are 40–250 mm thick, and the interior can be filled with polyurethane or mineral wool.

The sandwich panel itself is composed of an outer sheet of galvanized metal with a decorative coating, polyurethane adhesive, mineral wool derived from basalt, and a metal sheet with a decorative coating.

Specialized panels with outer layers composed of steel alloy or stainless steel are used when building fire-resistant partitions.

What slabs are required?

Partition sandwich panels can be fastened in both visible and hidden ways. When connected, those with visible fastenings slide into grooves on the outside of each plate. Panels with concealed fasteners are joined by a unique mechanism in which one plate penetrates the other through the side surface.

The following kinds of slabs are used when installing partitions in rooms:

• Unilateral. Single-sided slabs are made in such a way that the decorative finished surface is on only one part of the tile. This means that they can be used if the second part is hidden from people’s view or if the second side of the sandwich panel has to be finished.
• Double sided. Double-sided slabs do not have this feature – they are finished equally on both sides, so they can be used on any surface.
• Shockproof. Impact-resistant panels have a reinforced frame so they are resistant to mechanical shocks.
• Fire resistant. Fireproof sandwich panels are made from mineral wool and have a fire safety class of K0.
• Smooth and grooved. The surface of the panels can be smooth or corrugated – it all depends on the customer’s wishes.

Sandwich panels provide effective heat insulation. We can draw the following conclusions after comparing this material to others: it provides the same thermal insulation qualities at a panel thickness of 100 mm as aerated concrete, which has a thickness of 600 mm, cinder concrete, which has a thickness of 940 mm, and sand-lime brick, which needs to be 2240 mm thick to provide the same qualities.

Materials, consumables and tools

In order to install partitions made of the designated material, the following tools must be ready:

• riveter;
• drill;
• screwdriver;
• drill;
• bits for screwdrivers and hex heads;
• perforator;
• metal scissors (it is advisable to prepare both left and right ones);
• jigsaw;
• laser level;
• a circular saw;
• gun for applying sealant.

The materials that you must buy in advance are the necessary number of sandwich panels. Examining the substance beneath the dividers is important. For instance, you would need to purchase galvanized screws if these were metal sheets.

It is preferable to use anchor bolts if the panel is covered in concrete or if the fastening base is composed of it. Use screws or self-tapping screws if the installation will be done in an area with wooden surfaces installed.

Step-by-step DIY installation instructions

It is advised to adhere to detailed instructions when installing sandwich panels on your own:

1. Preparing the base. At the first stage, it is necessary to prepare the place where the partition will be installed. This place is cleared, all debris is removed and a frame is mounted on it. You must first pay attention to the condition of the base for installing the slabs: if the floor is uneven, it needs to be modified. To do this, dismantling measures are carried out, then a solution is made and the floor is re-filled in those places where there are defects. After complete drying, the floor is checked again for defects. When all deformations are eliminated, markings are made. The best choice for this process is a laser level, which makes several projections at once.
2. For mounting the frame use a profile pipe or timber guides. The diameter of the profile pipe should be selected based on the requirements for the strength of the partition. The partition itself can be assembled without a frame, but only using a tongue-and-groove connection system. This option is chosen when there is not enough space in the room to install a frame system.
3. Installation of partitions. To begin with, the insulating (damping) gasket is glued to the frame. Then, starting from the corner, install the first panel in the design position. The plate is secured with self-tapping screws, sealant or mastic is applied to the locking part of the panel. Next, install the next panel, pressing it tightly against the previous one. The width at the junction of all panels must be the same. By analogy, all panels are installed.

The final slab is sliced to the necessary length. Shaped elements can be installed and all seams sealed with foam or sealant. Panels are processed with the above-mentioned tools. After drilling and sawing, a brush must be used to remove any thin metal shavings that are still present.

Difficulties and errors

Errors and difficulties can occur during the installation process; these occur most frequently when the team of workers is inexperienced. Errors could be connected:

1. with transportation;
2. storage of slabs;
3. installation.

For instance, workers may fail to adhere damper tape, which could eventually cause the material to expand thermally.

Remember to treat raw materials with antiseptic compounds specifically; this will prevent mold and mildew growth even in completely dry rooms where installation is taking place.

Advantages and disadvantages

This material’s primary benefit for partitions is its light weight. Sandwich panels that are light in weight are fastened to the frame without applying undue strain.

Additional benefits in multiple areas:

• safety;
• sound insulation;
• high installation speed;
• no need for finishing;
• fire resistance;
• price;
• service life.

If the installation requirements are fulfilled, the panels have a long lifespan.

There is nothing wrong with this kind of content. Low strength and low impact resistance are two of the drawbacks. Because there is less chance of impact loads during the construction of internal partitions in buildings, this kind of raw material is ideal.

Budgeting

When creating an approximation, consider:

• dimensions of the future partition;
• the basis of its frame is wood or metal;
• dimensions of the panels themselves;
• workers" salaries;
• machine operating costs;
• labor costs;
• cost of fasteners and auxiliary materials.

The type and name of the partition panels that will be used, along with the address of the construction site, are all clearly stated in the estimate.

Material prices

The cost of one square meter of sandwich panels can range from 970 rubles to 4,000 rubles, depending on the kind of stove you choose.

They will charge 500 rubles per square meter to install a partition spanning 100 to 1000 square meters. In the event that more work is required, the price will be 450 rubles. Costs will differ based on the contractor and the area.
