Flat roofing systems are a critical component in modern architecture, especially for commercial and industrial buildings. Among the various materials available for flat roofs, Thermoplastic Polyolefin (TPO) and Built-Up Roofing (BUR) stand out for their unique properties and applications. This article delves into the specifics of these two materials, offering insights into their composition, benefits, and suitability for different roofing needs.
Understanding Thermoplastic Polyolefin (TPO) Roofing
TPO roofing is a single-ply roofing membrane known for its exceptional durability and energy efficiency. Made from a blend of polypropylene and ethylene-propylene rubber, TPO membranes are inherently flexible, making them ideal for various roof designs. The key features of TPO roofing include:
- Energy Efficiency: The reflective white surface of TPO roofing significantly reduces heat absorption, leading to lower cooling costs.
- Installation Flexibility: TPO can be mechanically attached, fully adhered, or ballasted, offering versatility in installation methods.
