The sandwich panel is a material that allows a very fast modular construction, with very good thermal and acoustic insulation coefficients, at a good price and whose elaboration requires little energy compared to other construction materials.
In addition, it is an increasingly easy material to find, you can even buy the Sandwich Panel online, which makes it ideal for many types of construction, especially roofs and those where speed is a requirement. , because a house made with this type of panels can be lifted very easily and in a short time.
The environmental compliance of building elements made of various materials is one of the most crucial issues to pay attention to.
An overview of the physical characteristics of sandwich panels indicates that all components of sandwich panels, including metal surfaces, organic finish, polyurethane (PUR) core fillers, etc., are safe components.
Such components remain protected from the assembly of materials to the building until their full use in the building after assembly. The safety of this coating system, which has been in use for more than 50 years, with the exception of minor revisions, is already apparent from previous experience.
Including applications requiring food safety, all materials used in sandwich panels easily meet the requirements of good hygiene practice.
Polyurethane as a core filler material offers significant benefits with its biological properties, such as being odorless, as well as being highly resistant to contaminants, mold and rot. In addition, its high insulation capacity also makes it the ideal filler material.
The ecological effects of the gases used to blow polyurethane are one of the important problems to be solved. From several studies carried out, it was found that the gases previously used in this field had harmful effects on the ozone layer. In an effort to find a solution to this problem, environmental conscious sandwich panel manufacturers have made great efforts and started using the environmentally friendly n-Pentane gas.
Sandwich panel and energy consumption
In a natural cycle, any form of energy consumption has some effect on the environment. Although the content of these effects is complex in nature, they are generally related to emissions released into the atmosphere.
The amount of energy used for heating has a direct effect on the ecological balance. For these reasons, high capacity insulation materials used in buildings offer significant environmental benefits, as well as an economic contribution.
In conclusion, the insulating materials used in buildings for a long time contribute to the protection of energy resources, in addition to contributing to the reduction of emissions into the atmosphere.
Sandwich panels are the most efficient cladding system from an economic and ecological point of view thanks to their polyurethane core with high insulating power, as well as their technology which does not create a thermal bridge. Although there is energy consumption during the production processes of the sandwich panels, it is considered to have minimal impact compared to the energy efficiency it provides during use.
The biggest advantage of sandwich panels in the energy cycle is their long service life. Its polyurethane filler material has been commonly used as an insulating material for about 50 years. Since the early 1960s, polyurethane has proven to be the most effective insulating material used in cold room systems, despite significant differences between indoor and outdoor temperatures.
Sandwich panel and recycling
Today, the fact that materials are recyclable is one of the most crucial parameters when it comes to the environment.
Thanks to their long service life, the unused parts of polyurethane materials used in buildings are insignificant compared to production volumes.
As long as they are disassembled carefully and without causing damage, the sandwich panels can be reused. In the event that a polyurethane material that has been used for many years cannot be reused due to damage or is no longer needed, there are three different recycling methods.
Since older versions of polyurethane materials still contain CFC gas, which is harmful to the ozone layer, these materials and raw materials are not suitable for recycling and therefore only energy recovery is considered.
Polyurethane materials that contain CFC gas and have been used for years can only be used in new materials under special conditions. Recycling the metal surfaces of sandwich panels is often preferred in the metal industry.
