Sandwich Panel: what it is and advantages

Sandwich panels, also called composite panels, sandwich sheet or polyurethane panelis a material used increasingly in the construction of buildings. This is due to its practicality and versatility, so it fits into any type of construction. The sandwich panel is basically made up of two outer shells and a corewhich is composed of a insulating material such as polyurethane, rock wool or other similar. Its main characteristic is precisely its structure that provides shape, resistance to climate and rigidity in the construction, as well as insulating properties, both thermal and acoustic.

Although this type of panel originated after the Second World War, with the aim of satisfying the needs of cold rooms given its excellent thermal insulation, it has currently become a revolution in construction systems and we can find it in the structures of various buildings such as commercial, agricultural or residential.

As we have pointed out, the sandwich panel has become a fundamental element in any construction and it is basically because of all the advantages it brings us:

• Protects against water, steam and air tightness.
• It has a excellent thermal insulation.
• Its metal outer plates resist atmospheric agents more aggressive.
• It has a high resistance and low weight.
• Its assembly is very simpleso it allows structures to be built very quickly.
• Its repair or replacement is easy.
• Because it is a mass-produced product, you can save a lot of costs.
• Its useful life is long and its low maintenance cost.
• The panels with rock wool core are fire resistant.
• There is the possibility of placing a sandwich panel on other coatings existing.

The sandwich panel is a very versatile, practical and easy-to-use material, which is why it has become an ideal solution for roofs and interiors, not only in industrial use, but also in residential construction.

As you have seen by reading this far, the sandwich panel has numerous advantages over other types of materials, such as uralite, which if not maintained correctly can cause long-term problems. In this sense, if you are thinking of changing the uralite of your roof for a sandwich panel, you should know that it is necessary to have a qualified work execution team to carry out the cover replacement.

Firstly, the team must assess both the surface to be changed and the type of sandwich panel to be incorporated, in order to provide a adequate budget. Furthermore, the package offered by the removal of uralite roof with asbestosmust include both asbestos removal and transportation and management of asbestos in landfillactivating the generic or specific security plan on each occasion.

But why should you remove the uralite from your roof? There are different reasons why opting for the sandwich panel is an excellent option:

• Because uralite roofs cannot be repaired.
• The asbestos contained in uralite can be easily released and cause serious lung diseases.
• The uralite cannot be waterproofed, so it can cause leaks and humidity to appear inside the home.
• If you want to go for solar energy you need an asbestos-free roof. In addition, installing solar panels in a sandwich panel is simpler and less expensive.
• Thanks to the installation of sandwich panel you will obtain greater insulation that will provide you with greater thermal comfort.

To remove the uralite it will be necessary for the team to write a work plan that guarantees both safety and health of workers through the execution of work. In addition, the amount of uralite to be removed must be taken into account, as well as the cost of the environmental analyzes necessary to guarantee that the asbestos fibers have not been left free after their removal. Having professionals to replace uralite roofs with new sandwich panel covers is essential for the execution of this work to be efficient and effective.
