Thermal and hydro insulation with PUR foam

Insulation of arched and shaped roofs

Description:

The need to repair roofs and additionally provide thermal insulation (because of ongoing increasing energy prices) and the discovery of the processing method for polyurethane in situ were, in the beginning of the seventies (1970) the stimuli to introduce progressive technologies – the spraying of hard polyurethane foam directly on the roof or roofing. The first applications were performed in the USA, the country with one of the largest markets for this technology up until today. Thermal insulation of roofs is important not only from the viewpoint of energy savings in the winter (heat loss) but also in the summer when air conditioning units consume a lot of energy in large buildings. Currently the reason to reduce the consumption of fossil fuels and the reason to slow global warming are comparable.

The pur foam spraying technology creates a seamless waterproof and thermally insulating layer. This provides perfect sealing of all critical spots – passages for air conditioning equipment, necks of distribution lines etc. Polyurethane materials are not resistant to sunshine and so the surface may start to degrade after some time. In order to protect the insulation from sunshine we apply acrylate and silicone UV coatings with a service life of up to 40 years.

The polyurethane roof coat is often used for the reconstructions of flat, slanted or variously shaped roofs, but it can also be used for new buildings.
