【Labor Shortage Resolution】10-Year Warranty (with Extension) Modified Asphalt Waterproof Sheet
Since only the joints of the waterproof sheet are melted for joining, anyone can easily install it! Using a small burner, there is no need for gas refilling. *Shortens construction time and reduces costs.
The modified asphalt waterproof sheet "OS-sheets" is a modified asphalt sheet using a cold self-adhesive method, which excels in adhesion to the substrate and breathability. The joints and edges of the sheet are fused using a torch burner. It is a hybrid type modified asphalt sheet that combines the advantages of the self-adhesive method and the waterproofing of the torch method, reducing the heat generation during installation to below 10% compared to conventional torch methods. It is also environmentally friendly and offers economic benefits. 【Features】 ■ Hybrid sheet combining the advantages of cold self-adhesive and torch methods ■ Excellent adhesion to the substrate and breathability ■ Reduces heat generation to about 10% ■ Environmentally friendly and labor-saving ■ Shortens construction period ■ Addresses labor shortages ■ Economic benefits 【Specifications】 Modified asphalt sheet (synthetic fiber non-woven fabric + modified asphalt) 1.0m × 8.0m, thickness 4.0mm, surface with sand granules, back with partial adhesive layer 【Other Features】 ■ The partial adhesive layer on the back allows for adhesion to the substrate, providing both breathability and waterproof performance with a single sheet. ■ The sheet joints are fused through heating with a torch burner, ensuring complete integration and waterproofing. ■ Installation is possible even over large areas using only a handheld torch burner.
