Roofing & Building Membranes Archives

Roofing and building membranes are critical components in construction, providing waterproofing, weather resistance, and structural protection for a variety of buildings. Composed of bitumen and reinforced materials, roofs and membranes are designed to create durable, long-lasting surfaces that withstand environmental stressors. Roofing compounds and asphalt additives can enhance performance by improving flexibility, adhesion, and resistance to temperature fluctuations. Bitumen building membranes offer reliable solutions for flat and sloped roofs, while asphalt roofing solutions contribute to energy efficiency and overall building longevity. Their versatility, durability, and protective properties make them indispensable in both residential and commercial construction projects.

Boosting Roofing Performance with a Polymeric Additive

In today’s demanding construction environment, roofing systems are expected to do more than just provide shelter. They must withstand extreme temperatures, resist water ingress, and maintain long-term durability under mechanical stress. Achieving this level of performance starts at the formulation stage. For manufacturers working with roofing membrane formulations, roofing underlayments, and ice and water barrier systems, a bitumen-friendly polymeric additive like PGXpand® proves [...]
