2. Core Explanation
• Made from high-quality, high-purity alkali-free glass fiber, it offers stable mechanical properties and is resistant to breakage and deformation.
• Aging-resistant and UV‑stable, suitable for long-term outdoor use; resistant to aging and embrittlement, ensuring a long service life.
• The asphalt exhibits excellent penetration and bonds tightly with the waterproof membrane, ensuring no delamination or adhesive failure, thereby delivering more stable waterproofing performance.
• Customizable basis weight, width, and roll length to meet the dimensional and load requirements of various roofing projects.
