THE INSULATION OF FLAT ROOFS –INVERSED ROOF THE INSULATION OF FLAT ROOFS –INVERSED ROOF

• Insulation of flat roof with the traditional method

the insulation is under the waterproofing (EPS-STONEWOOL)

• Insulation of flat roofs with the inversed roof principal

the insulation is above the waterproofing material (XPS)
