There are different types of sandwich panels, each with its own characteristics that determine their application. One type of prefabricated panel is the hidden screw sandwich panel. In this article, we intend to examine hidden screw sandwich panels and their applications and features.

That is why this type of sandwich panel is called a hidden screw sandwich panel. Like other sandwich panel models, this sandwich panel is made up of two aluminum, aluzinc or galvanized sheets and a polyurethane insulation foam, polystyrene, rock wool or glass wool. These panels are designed in such a way that during installation, the shape of the overlaps makes the screws used in the installation of the sandwich panel invisible.

Hidden screw sandwich panels are only available in the wall sandwich panels type. Hidden screw sandwich panels are used in the construction of wall facades, partitions, dividing walls, etc. The hidden screw prefabricated panel is completely similar in functionality to other sandwich wall panels, differing only in foam material and color. It may also differ in width and installation type.

Features of hidden screw sandwich panels

In addition to the beautiful and uniform appearance they create during installation, hidden screw sandwich panels also have other notable features. The most important features that can be considered for this type of panels are:

• Insulating foams have properties such as being fireproof and antibacterial, which is why they are used in the construction of clean rooms, refrigerated rooms, and medical and laboratory halls.
• Hidden screw sandwich panels are considered good insulators for moisture and have a low heat transfer coefficient. For this reason, they are considered good insulators to prevent energy loss. In addition, they have fireproof and fireproof properties, which makes them a practical product.
• These sandwich panels have excellent resistance to environmental factors such as temperature, sound, humidity, etc.
• They have high physical and mechanical resistance.
• Hidden screw sandwich panels have high resistance to pressures and forces caused by collisions or earthquakes, which is due to the design of the grooves on them.
• These prefabricated panels have good resistance to factors such as chemicals, acids, bases, etc. and are not conductors of electricity.
• The most important advantage of hidden screw sandwich panels is their beautiful appearance. These panels are installed in such a way that the connecting screws are not visible, and therefore have a uniform and beautiful appearance.
• Another feature of these panels is their light weight, easy and quick transportation and installation, which reduces project completion costs.
• Like other sandwich panels, hidden screw panels can be dismantled and can also be used second-hand.

Sandwich panel sheet material, hidden screw wall

These panels are generally used in interior design and decoration, and as we mentioned, hidden screw sandwich panels are only produced in the wall type. The high durability and resistance of these panels, as well as the very low maintenance costs, make these panels very popular among all types of wall panels.

The sheets used in the manufacture of hidden screw sandwich panels are mostly made of metals such as aluminum, galvanized, and aluzinc, which have features such as high resistance, colorability, waterproofness, and so on.

Sandwich panel insulation material, hidden screw

Like other prefabricated panels, hidden screw sandwich panels have properties such as heat, cold, sound, moisture insulation, etc. The best type of insulation that can be considered for these types of panels is polyurethane insulation, which, in addition to being lightweight, also has properties such as antibacterial, antifungal, waterproof, fireproof, and fireproof.

Of course, another type of lightweight insulation used in wall panels, including hidden screw sandwich panels, is polystyrene insulation, which makes the structure very lightweight and at the same time resistant to moisture and sound. However, such insulation is not fireproof and cannot be used in high-risk environments. Despite this feature, due to their very reasonable price, polystyrene panels are considered among the most popular hidden screw sandwich panels.

Types of hidden screw panels

There are various types of hidden screw sandwich panels, which are classified mainly based on the design and placement of the sheets and their insulation. These panels include: Two-sided sheet, one-sided sheet and one-sided foil, one-sided sheet and one-sided nylon, two-sided nylon, one-sided sheet and one-sided paper, two-sided paper and two-sided foil. Each of these types of hidden screw sandwich panels has features that determine their application.

How to install hidden screw sandwich panels

In such panels, the connection should be such that first one of the panels is screwed onto the structural skeleton for a firm and stable connection, and then the next overlap panel is placed on it. In this way, the connecting screws of each panel will be hidden under the overlap section of the next panel. Such a feature makes the wall facade integrated and has a more beautiful appearance.

Advantages of using hidden screw sandwich panels

These sandwich panels are very light and have high strength and resistance. In addition, they have a more beautiful appearance compared to other wall panels. Also, due to the special way of installing hidden screw panels, such structures have higher durability and stability.

Applications of hidden screw panels

This sandwich panel is used in various industries due to its unique features, the most important of which is the use of hidden screw panels in interior design and decoration, cold storage construction, shed construction, clean rooms, recording studios, various types of enclosures, etc.

Hidden screw sandwich panel price

The price of this type of sandwich panels is determined by factors such as the type and quality of the material used, the area and dimensions requested by the buyer. However, hidden screw panels are cheaper than other panels.
