Vulcanized EPDM membranes are heat-treated. This process makes them more durable and resistant to environmental factors. They are ideal for roofs that face harsh weather conditions.
Non-vulcanized EPDM membranes, on the other hand, remain uncured. They are more flexible and easier to install around roof features like vents or pipes. However, they might not last as long as their vulcanized counterparts.
Factors
Several factors influence the choice of an EPDM membrane for your roofing project:
-
Roof slope and structure design play a crucial role in selecting the right type of membrane.
-
Local climate conditions such as temperature extremes or UV exposure can affect membrane performance.
-
The building's usage might require specific types or thicknesses of EPDM to ensure longevity.
Moreover, compatibility with existing roofing materials is essential to prevent issues post-installation. The need for insulation under the EPDM layer must also be considered since it impacts thermal efficiency.
Lastly, integrating a drainage system with your chosen membrane ensures water is properly channeled away from the roof.
Installation Considerations
System Considerations
After selecting the right EPDM membrane, it's crucial to consider the installation system. Different adhesives play a pivotal role in this process. Water-based adhesives are preferred for their lower volatile organic compounds (VOCs) emissions. They contribute to a healthier environment during and after installation.
However, if strong initial tack is necessary, solvent-based adhesives might be more suitable. They provide robust bonding from the start but come with higher VOC emissions.
For those seeking quick installation, self-adhesive membranes are an excellent choice. These require less preparation time and can significantly reduce labor costs.
Adhesives Types
