Not all SBS membranes are the same, however. Understanding the surface layer is often critical for selection. Each type of surface layer—slate granules, PE film, sanded surfaces Aluminum foil or self-adhesive surfaces—have their given advantages and particular scenarios where they apply.
In this blog post, we’ll guide you on how to choose the right SBS membrane based on your project’s specific needs.
