Lighten the burden of waterproofing work under the scorching sun! OS-sheets waterproofing system.

Reduce fire usage by 90% to improve harsh working conditions in summer! Suppressing fire also helps prevent heatstroke.

Especially during the summer season, the work of heating and melting the entire backside of the sheet with a large propane gas burner in the torch method is an extremely harsh environment for workers. By integrating the application process of ventilation sheets and waterproof sheets, which use a large amount of fire, with factory machinery, OS-sheets have improved quality and reduced on-site processes. Furthermore, since OS-sheets only require torch work at the sheet joints, it is about 1/10 compared to conventional torch methods. This significantly reduces the amount of torch burner work, alleviating the burden on workers. CO2 emissions are also reduced, allowing for construction that considers both workers and the environment. This reduction in processes and workload creates more flexibility in the construction schedule, enabling work to be done while avoiding the hottest times of the day, which helps prevent heatstroke. *For more details, please refer to the PDF document or feel free to contact us.*

basic information

【Reduction of Workload Part 1】 ★ Only the joint area is heated Compared to conventional sheets that require heating the entire backside, OS-sheets only heat the joint areas, reducing the heating area to 1/10, significantly decreasing the use of open flames by workers! While also greatly reducing CO2 emissions, it has greatly improved the working environment on site. 【Reduction of Workload Part 2】 ★ Two functions in one sheet In typical modified asphalt cold torch methods, two sheets are used: a "base sheet" (ventilation layer) and a "top sheet" (waterproof layer), with the entire backside of the top sheet being heated during installation. OS-sheets perform the bonding process of the base and top sheets using factory machinery, resulting in high-quality bonding that is not dependent on the skill level of the workers. This allows for a reduction in the sheet layering process on site while enhancing quality, thus reducing the workload. Additionally, the adoption of self-adhesive technology makes the work simple and speedy. Through various innovations, this sheet improves installation quality while shortening construction time and reducing the burden on workers. *For more details, please refer to the PDF document or feel free to contact us.
