Waterproofing and energy rehabilitation of an existing roof without providing for the demolition of the existing layers. The new panel is bonded on the existing membrane.

If the old covering has good adherence properties, once repaired, it can be reused as vapour barrier for the new thermal insulation layer (its thickness must always be checked by the specialised technician in order to prevent condensation beneath the vapour barrier). The new insulation is mechanically fixed or bonded with MASTICOLL or bonded with melted bitumen. The new covering will be mechanically fixed to the foot of the projecting parts.
