Sandwich panels are a very effective insulation system, with an efficient performance in all types of climates. For this reason, it is an indispensable tool in the energy renovation of buildings, as well as in new construction.
They consist of two metal sheets, normally made of steel, with an insulating core, which can be made of PUR, PIR, mineral wool, EPS (expanded polyethylene) sandwich panels or honeycomb (polystyrene core). In this case we will talk about the durability of PIR/PUR sandwich panels, which is why they are widely used in roofs, ceilings and walls. In addition to their excellent insulating properties, their lightness and speed of installation make them a very suitable option in the context of energy efficiency and sustainable construction.
Environmental benefits of PIR/PUR sandwich panels
With a view to the 2030 agenda, the world of construction is choosing materials and building systems that are increasingly environmentally friendly. PIR/PUR sandwich panels have a lot to contribute to the decarbonisation of the sector.
They undoubtedly contribute to the sustainability of buildings by improving their energy efficiency and thus reducing energy consumption.
In addition, both the metal of the panel and its core can be recyclable materials, thus favouring a more sustainable waste management. Moreover, the panels are industrially manufactured and can be cut to size, according to the needs of each project. In other words, material waste is minimal.
Quick assembly and durability
Another advantage of PIR/PUR sandwich panels is that they are easy to install. As lightweight elements, they require hardly any technical means, as they can be installed manually under certain circumstances. This also contributes to the sustainability of PIR/PUR sandwich panels, because the emission of pollutant gases is reduced as no machinery is required for installation. In addition, the speed of installation also reduces construction time, another great environmental advantage.
On the other hand, the high durability of PIR/PUR panels varies depending on environmental conditions. In saline environments, for example, it may be less durable. In this sense, it is important to choose the right finishes depending on the installation environment. In this line, another advantage is that the panel arrives ready from the factory with all kinds of finishes.
It is also advisable to plan maintenance, to schedule regular inspections and cleaning to check that they are in perfect condition.
Structurally, PIR/PUR sandwich panels are a self-supporting material. This means there is less need for metal or wood to create their support, which results in lower costs, as well as less energy and labour costs.
In summary, the durability of PIR/PUR sandwich panels is key to their consideration as a material that contributes to the sustainability of buildings, as well as their recyclability and ease of installation.
