Metal roof waterproofing, rust prevention, and heat insulation methods! Using waterproof materials that reduce odors and toxicity!
The "Big Sun MR Method" is a specialized construction method for metal roofs that uses a highly flexible polymer cement-based waterproofing material primarily composed of acrylic resin, along with a solar heat reflective coating. Thanks to the highly flexible waterproof coating, which excels in durability and weather resistance, it follows the expansion and contraction of the substrate, maintaining waterproof performance over the long term. The flexible coating also has soundproofing effects, reducing the sound of rain. Additionally, due to the effects of the heat-reflective coating, it suppresses the rise in indoor temperatures, thereby reducing energy costs for air conditioning during the summer. 【Features】 ■ Excellent waterproof performance ■ Excellent rust prevention performance ■ Suppresses the rise in indoor temperatures ■ All constituent materials are environmentally friendly products *For more details, please download the PDF or feel free to contact us.
