Technology background of the polyurethane foam insulation of trapezoid sheet roofs

An anti-corrosion and adhesion improving painting is required as preparatory work. The sprayed polyurethane insulating foam covers the defects of the roof, stops the leaks through the gaps of the trapezoid sheet roofs and through the holes of the sheet-fixing screws.

In the case of external insulation, the trapezoid sheet will not heat up in summer days, therefore the internal temperature fluctuation of the building will cease to exist and the dilation gaps of the roof structure will be remedied as well. Due to its density it makes the roof more stable and even walkable. It prevents the internal formation of condense water. The load caused by the insulation is minimal, a foam layer of 3 cm thickness means a loading of 1,8 kg/m2.

The characteristics of the applied material

  • foam density: 35kg/m3

  • compressive strength: 150K.Pa

  • thermal conductivity coefficient: 0.023W/mK

  • fire safety class: B2 – self-extinguishing
