Features of OS-sheets

The conventional layering process has been shortened to one step! Sandwich structure of modified asphalt layer.

"OS-sheets" are single-layer sheets that enable the functions of the traditional two-layer system: a "bottom" ventilation layer and a "top" waterproof layer. As a result, the conventional lamination process has been shortened to one step, allowing for a reduced construction period. 【Features】 ■ Sand granules: Protect the waterproof layer and prevent UV degradation ■ Modified asphalt: Asphalt with additives such as rubber and plastic ■ Synthetic fiber non-woven fabric: Improves dimensional stability and tensile strength ■ Partially adhesive self-adhesive layer: Maintains breathability while also excelling in insulation *For more details, please refer to the PDF document or feel free to contact us.
