The hybrid waterproofing method, which excels in airtightness and weather resistance, protects buildings for a long time.
The Z Roof uses galvanized steel sheets as the base material and standard molten zinc-coated steel sheets, offering superior corrosion resistance compared to other company's deck roofs. Additionally, the Yodo GL Eco Green steel sheet used as the base material has a special coating that does not contain hexavalent chromium, which is an environmentally harmful substance. The Z Roof Type 1 features a structure that conceals the screws used to secure the insulation and sheet at the joints, enhancing the aesthetic appeal from the interior side and preventing the falling of metal shavings generated when fixing the screws to the steel sheet.

basic information
The roof is equipped with fire prevention and fire resistance performance as required. By combining the "Z Roof," which meets fire resistance standards, with "PVC sheets" that comply with fire prevention performance, it can be adapted to fire prevention areas, quasi-fire prevention areas, and areas designated under Article 22 of the law. Even when combined with Z Roof Type 3, insulation materials, and waterproof sheets, the roof remains lightweight at 16 kg/m², resulting in an eco-friendly structure with excellent external insulation and seismic resistance, which can reduce construction costs. Since the metal surface is not exposed, rain noise is minimized. The thickness and variety of insulation materials are abundant, making it effective for energy-saving measures under the "Building Energy Conservation Act." As it uses a dry construction method, there is no need for concrete pouring and curing on the roof, which shortens the construction period. It is also effective for leak prevention in areas with heavy snowfall.
