PUR and PIR Sandwich Panel Roofs
To talk about PUR and PIR Sandwich Panel Roofs, it is necessary to emphasize the function and the components of PUR and PIR Sandwich Panels. In the following we will explain all the characteristics that must be taken into account when choosing the type of sandwich panel for a construction site or project.
It should be noted that the use of high quality raw materials and the application of strict quality controls allow us to offer product guarantees of up to 10 years depending on the manufacturer.
PUR and PIR sandwich panels are manufactured to insulate with the safety of your building in mind.
Nowadays, basic protection needs are required in the field of construction, so PUR and PIR rigid foam sandwich panels are nowadays one of the preferred options for engineers and architects, to guarantee a construction with high thermal insulation values.
PUR and PIR Sandwich Panel Roofs consist of an insulating core of rigid polyurethane (PUR) or polyisocyanurate (PIR) foam adhered to two walls, which are usually metal. The metal layers are usually made of steel or aluminium.
What are the differences in PUR and PIR Sandwich Panel Roofs?
The difference lies in their fire behaviour. The PUR foam insulation board has less fire resistance, while the PUR foam insulation board has less fire resistance.
PIR foam insulation board can have excellent fire resistance due to its cyclic structure.
PUR and PIR sandwich panels are one of the best options in terms of insulation and safety due to their functionalities and advantages, especially PIR panels against fire. Building codes and legislation are becoming stricter and stricter with regard to the fire performance of building envelopes. Polyisocyanurate rigid foam (PIR) is a variant of polyurethane foam (PUR). At first glance, it has practically the same appearance, mechanical and thermal properties, but its main difference is that it reacts safely to fire by forming a carbonised surface layer that protects and prevents the penetration of fire into the interior layers of the dwelling.
PIR is a polyisocyanurate polyurethane foam composed of polyol and isocyanate, with excellent qualities. PUR, on the other hand, although still a polyurethane foam, is composed of a combination of polyol and diisocynate.
PUR and PIR Sandwich Panel Covers have a high insulation capacity and guarantee the good preservation of the goods inside the building. However, PIR foam is 10% more insulating and is also more tolerant to chemicals.
Due to its different chemical composition, polyisocyanurate (PIR) provides different physicochemical properties for sandwich panels incorporating it as a core compared to panels using polyurethane (PUR).
What are the thermal and dimensional properties of PUR and PIR Sandwich Panel Roofs?
PIR panels are temperature stable from -200°C to 120°C, and PUR panels obtain thermal stability from -150°C to +80°C.
The dimensional stability of the PIR sandwich panel has a better stability and a better mechanical strength compared to PUR.
In short, PIR has an advantage over PUR, both in thermal insulation and in thermal and dimensional properties. All PUR and PIR Sandwich Panel Roofs pass strict tests that comply with ASTM E84, where the most appreciated in generating less smoke in case of fire would be the PIR.
Advantages of using PUR and PIR Sandwich Panel roofing in your construction:
Like asphalt Deck Roofs and synthetic Deck Roofs, PUR and PIR Sandwich Panel Roofs are recyclable. PUR and PIR Sandwich Panel Decks are made of prefabricated panels, making them sustainable to manufacture and very light to transport to the construction site. The insulating capacity of the polyurethane sandwich panels helps to reduce energy consumption, and the construction of a building with PUR and PIR Sandwich Panel Roofs produces very little waste, which helps to make the construction process more sustainable.
Great thermal insulationPIR is one of the thermal insulators with the lowest coefficient of thermal conductivity: 0.022 W/mk. It is a homogeneous insulator at all points of the panel.
It has a lower insulation thickness due to the low coefficient of thermal conductivity of the polyurethane foam, thus optimise the usable space to 100%.
MackintoshesThey have virtually no water absorption due to the closed cell structure of the polymer.
High mechanical properties (high rigidity and low weight of the panels), which facilitates and economises transport, handling, installation and structural sizing. Easy machining and cutting.
Fire safety.
At COVER Industrial we strive for safety in the workplace and in your home, providing high quality work for the life of people and property, avoiding as much as possible that they may be in danger in the event of a fire.
