Beyond the small heat conductivity, the long lifespan is one of the most important features of the polyurethane foam.
It is also advantageous that the heat loss in a seamless connection is much smaller than in traditional insulation boards.
Those are not in position to adapt to the unevenness of the surface.
Polyurethane spray foam is so elastic, that it can compensate shrinkage and expansion motions within 1,0 cm/lfm. No static problems occur, because the old roof panel is stressed with little weight.
By means of ECOPUR-spot-foam, the gaps and cracks are completely closed. The function is served until the building stands.
Different materials and roof forms pose no problems. You can renovate cement asbestos-, bitumen-, mush-, concrete-, wood-, foil-, metal-, shed-, and glass-roofs with ECOPUR spray-foam, which is system from the company ECOPUR. Problematic spots like dome lights, pipe penetrations, air conditioners, ventilators, fireplaces, roof inlets are tied technologically excellent and absolutely tight in the roof panel.
After the restoration, the roof is thermally immobilized, that means the tensions caused by temperature and weather are almost cut out. Moisture infiltration is not possible by the good background and ply adhesion, not even in mechanical damage of roof panel.
A closed insulation layer comes into being by an insulation of a cooling pipe and this way, it doesn’t permit dripping water formation.
