Short construction period and contributes to cost reduction! Can be installed over any roof.
We would like to introduce the overlay construction method using "Ondulin Classic." This method is a cover construction that can be performed in the same way as a regular roof without removing the existing roof. Classic is lightweight at less than 4 kg/m² and does not incur additional costs for the structure. Furthermore, it can be applied to any type of roof, including iron, steel, asbestos cement, membranes, and tiles. 【Advantages of the Cover Method】 ■ No waste materials are generated, saving both demolition and waste disposal costs. ■ The removal costs for roofs containing asbestos are high, but this method can help save those costs. ■ Short construction period. ■ No disruption to daily life. ■ The double structure of the roof reduces noise from rain and improves insulation. *For more details, please refer to the PDF document or feel free to contact us.
