What technical requirements define what is the difference between built up roofing and modified bitumen for asphalt or bitumen modification?
Built-up roofing (BUR) consists of multiple layers of asphalt and reinforcing fabrics, creating a durable, layered system. In contrast, modified bitumen roofing involves a single-ply membrane that incorporates modifiers like APP or SBS for enhanced flexibility and UV resistance. The key technical differences lie in the application methods-BUR is typically installed hot or cold, while modified bitumen is often applied using torching or self-adhesive techniques. Additionally, BUR offers greater redundancy, while modified bitumen provides easier installation and repair.
