POLYURETHANE it is a synthetic and duroplastic material, highly cross-linked and non-fusible, wich is obtained from the mixture ot two components generated by chemical processes: Isocyanate and Polyol.
Rigid polyurethane is the most efficient and durable thermal insulating material. Its low conductivity conferred by the closed cell structure and its innovative manufacturing technology have placed it at the forefront of products that help save energy through thermal insulation.
It is the insulation material par excellence in multiple industrial applications ans is undoubtedly the most widely used product in the insulation of industrial and residential buildings due to its energy efficiency.
There are two manufacturing systems that lead to two differentiated products:
•Rigid polyurethane foam applied in situ by projection, or projected polyurethane, wich is obtained by simultaneously spraying the two components on a surface called the substrate.
•Rigid polyurethane foam applied in situ by casting, or injected polyurethane, in wich the two components are physically mixed by beating and introduced into a cavity where expansion is carried out.
Among the properties of POLYURETHANE we can mention the following:
•It is the material with one of the lowest thermal conductivity values, 0.031 W/m K.
•The maximum level of insulation is achieved with a minimum thickness.
•Helps reduce the energy consumption of a building.
•The insulation capacity does not decrease with the passage of time.
•It is 100% waterproof but allows perspiration which prevents condensation.
•It complies with grade of impermeability of facades according to the CTE.
•There are no joints or gaps and thermal bridges are avoided.
•Great adherence to almost any surface. It adapts to any shape.
•It is an excellent sound insulation.
•It is harmless product for people and the environment. It does not gives off gases or fibers.
•Fire resistance classification from B, S1-d0 to B S3-d0
•Has a compressive strength greater than 160 kPa.
•Density between 35 and 45 kg/m3
