10. Feb 2026 | OnlineEC Webinar on behalf of Omya: From heat reflection to energy savings: The role of hollow microspheres in cool roof coatings
15.00 h CET
This webinar shows the role of hollow glass microsphere in enhancing the comfort properties and cooling energy savings linked to roof coatings. By increasing the Solar Reflective Index (SRI) and lowering the thermal conductivity, Omyasphere lightweight filler can reduce the heat accumulated on and below coated surfaces.

Content
Cool roof technologies are gaining attention as an effective strategy to reduce urban heat and improve building energy efficiency. This webinar shows the role of hollow microspheres in enhancing the comfort properties and cooling energy savings of roof coatings. By lowering thermal conductivity and increasing the Solar Reflective Index (SRI), these lightweight fillers significantly reduce heat accumulation on surfaces. Comparative studies of multiple formulations highlight their impact on key properties such as density, elongation, and durability, demonstrating improved insulation and mechanical performance. The findings reveal that coatings incorporating hollow microspheres lead to cooling energy savings contributing to lowering CO₂ emissions from building operations. This approach offers a sustainable solution for regions with warm environmental conditions, aligning with global energy efficiency and climate goals.
Target audience:
Professionals at paint and coating manufacturers across key roles:
- General Management / Assistant Manager
- Plant / Production Manager / Process Engineer
- Research & Development / Laboratory
- Technical Services / Quality & Environmental
- Purchasing
- Sales & Marketing / Product Manager
