Double-layer board – what is it?

Sandwich panels, also available as “panel boards” are a composite building material used to enclose walls and roofs and form the body of a building. We distinguish between wall and roof sandwich panels. Regardless of the type, they consist of the same elements: steel, profiled sheets in the outer layers and an inner insulating layer, also called filler or core.

How is this material created?

The process of creating sandwich panels consists of several very important steps and is an iterative process, no matter what type of material we are dealing with. It is carried out in an automated manner.

First, a sheet is prepared – with the shape and parameters derived from the technical documentation. It is the one that forms the outer layer of each sandwich board and is a typically structural element. This is followed by the core of the material, or insulation layer. Various materials are used for this purpose, but the most common are mineral wool, polyurethane foam or polystyrene foam. State-of-the-art products, including Kingspan sandwich panels, feature innovative cores with increased values for particular parameters. The next step is to connect the sheet metal to the insulation core. This stage takes place on the production line. It is based on the phenomenon of adhesion, or the ability of materials to bond with each other.

However, before the sandwich panel is transported, it undergoes quality control. Among other things, specialists check whether its thickness and shape agree with the technical recommendations for the product. The slab is also sent for so-called seasoning – a break during which it acquires the right temperature. For delivery, the material is properly secured.

What are the characteristics of panelboards?

Wall and roof sandwich panels have many features that are appreciated by every construction investor. They are primarily a highly thermally insulating material. Thus, they prevent heat from escaping from the building and contribute to creating the desired thermal comfort inside the house (or another type of building). They also offer favorable sound insulation. This feature is important, especially in construction projects taking place in close proximity to traffic arteries or in the creation of industrial buildings. In addition, the material shows high resistance to mechanical and even fire damage. It is lightweight and handy, making installation faster, and available in a variety of aesthetic and size options. Also in favor is the relatively low cost of purchasing such a product.

Sandwich boards – application

Due to the aforementioned features, sandwich panels are used in the construction industry in the broadest sense of the term, and co-create, among others: production halls and warehouses, office and commercial buildings, public buildings, cold stores and freezers, logistics centers, various types of workshops, as well as buildings on farms.

Definition of sandwich panels

sandwich panel is a building material that, as the name implies, consists of two layers: sheet metal on the two, outer sides and an insulating core in the center. You can also find it under the name “panel boards”.

Depending on whether we are dealing with wall or roof sandwich panels, the product is used to enclose walls or roofs and thus create a building block. As it is an extremely aesthetic material, it is also responsible for giving the building an attractive, neat and modern appearance. In turn, its insulating properties allow investors to create buildings with the desired thermal and acoustic comfort.

What does production look like?

Whether a wall or roof panel is being created, production looks very similar and consists of the same key steps.

  • Creating sheet metal
  • – properly shaped, durable and with planned aesthetics. It is she who gives the entire board a certain structure and solidity.
  • The formation of an insulating core –
  • the peculiar heart of any double-layer board. This layer is formed from a variety of materials, but mineral wool, polyurethane foam and polystyrene foam lead the way, as materials with the most favorable thermal insulation parameters.
  • Combining the outer layer with the inner layer –
  • that is, sheet metal with an insulating core. This uses the phenomenon of adhesion, which is the ability of materials to bond with each other.
  • Quality control and so-called seasoning
  • – a very important stage, during which sandwich panels are checked for compliance with technical documentation and “rest”, acquiring the right temperature.

* It is worth knowing that state-of-the-art insulated panels use different and improved cores. This is the case, for example, at Kingspan, a leader in the production and sale of this material. In addition to standard PIR cores, the manufacturer’s IPN uses the innovative QuadCore™.

Key advantages of the material

Insulated panels are a material with many advantages. It is characterized by light weight, yet high mechanical and fire resistance . It is distinguished by its low thermal conductivity coefficient (this indicates its excellent thermal insulation properties) and is available in a variety of aesthetics and many sizes. In addition, it offers good sound insulation – this is appreciated, for example, by investors planning to create a building in close proximity to streets. In contrast, in the context of sustainable construction, close to Kingspan’s policy, sandwich panels are made with great care for the environment.

Double-layer boards – where are they used?

Having learned the main advantages of the material, it is not surprising that it is used in the construction industry in the broadest sense of the term and co-creates, among others: production halls and warehouses, office and commercial buildings, public buildings, cold stores and freezers, logistics centers, various types of workshops, as well as buildings on farms.

Fastening belts – what are they useful for?

Lashing straps and Belts

Lashing straps are commonly used in the shipping and transport industry. They are primarily used for the optimal securing of loads, effectively preventing them from shifting on the truck bed. In the construction of the standard model, we distinguish components such as a fabric strap, tensioner, hook and additional accessories that increase the level of protection. In what situations are the fixing trowels best?

Proven way to deliver goods intact

Fastening belts are characterized by above-average strength and resistance to the effects of various external factors (e.g. chemicals, moisture, UV rays). In addition, they are relatively light and handy, which greatly facilitates the assembly process – one person is enough for this.

Thanks to the soft and flexible structure of the material, the belts effectively absorb any shocks and do not have a destructive effect on the delicate surface of the protected packages. The properties mentioned above guarantee the delivery of the cargo to the addressee without the risk of its mechanical damage or causing a hazard on the road. It is also worth mentioning that the fastening belts are extremely universal. They can be used to secure both small and large-size goods.

Many types of lashing straps to choose from

Lashing straps of various construction types are used to stabilize the loads. For years, the traditional versions with a tensioner have been the most popular, as they can easily withstand loads of several tons. Items with a length of 2-4 meters are perfect for securing furniture, electronics and household appliances, bicycles or small fishing boats. On the other hand, the ones over 4 meters are able to anchor, for example, quads, construction machines, Dutch houses and concrete tanks.

Also noteworthy are the three-point models, intended mainly for attaching passenger cars to carriages. The division of the discussed elements can also be made by considering the color of their labels. The blue color indicates that the belt is made of polyester, a material resistant to mineral acids and retaining its performance parameters at low and high temperatures. The green color symbolizes polyamide (not susceptible to alkaloids), while the brown color relates directly to polypropylene (slightly less durable than other materials). It is also worth remembering that the fastening belts are available in various widths – from 25 to 50 mm.
