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.

Kingspan – manufacturer of easy to install sandwich panels

The production of sandwich panels for walls and roofs should be carried out under perfect conditions because only then is it possible to achieve the right parameters.

Thermal insulation parameters.

Kingspan, a manufacturer of sandwich panels that are easy to install, is the undisputed market leader. The company also manufactures accessories for the refrigeration industry and doors.

All items are competitively priced and made from the best materials available. Sandwich panels are very economical and have good thermal insulation parameters. They are ideal for large projects that need to be completed quickly. The production utilizes the latest technology, so the panels are manufactured in an extremely short time. Kingspan panels also have a low weight and very high strength. All these factors mean that they are being used more and more successfully in many constructions. This means that they can also be used for the construction of cold stores and freezers.

Additional accessories

When buying sandwich panels it is worth equipping yourself with accessories such as:

– blinds- natural lighting system- a masking strip- flashing

Sanwich panels – Kingspan

Companies involved in the production of foodstuffs must obligatorily equip their facilities with cold rooms. This will ensure that the products do not deteriorate and retain their value for longer. The best cold rooms consume small amounts of energy and have a low life-cycle cost. When choosing sandwich panels, it is worth paying attention to the standard of workmanship and the material used. The quality of Kingspan products is regularly confirmed by tests and certificates. All sandwich panels are carefully manufactured with attention to the smallest details.

Mounting of a sandwich panel.

All these aspects make this company’s products a popular choice for customers. The sandwich panel can be installed vertically or horizontally. It works perfectly as a lightweight wall cladding regardless of the type of building. If the outside temperature is generally more than 0 degrees Celsius it is a good idea to use lightweight panels. The greatest advantage of the sandwich panel system is its core. The excellent insulation is due to the core and the various coatings.

 An interesting solution is also the concealed fixing system, which allows to hide any imperfections and make the construction look better. The standard length of the panel ranges from 3 metres to 13 metres, but can be cut and adjusted as required. The largest possible length is 15 metres, but this is rarely used.
