You will always find BaySystems ready to listen to your needs and give you a reliable response in your language. We also draw on the wide-ranging polyurethane expertise of our colleagues from Bayer MaterialScience, as producers of high-quality polyurethane raw materials. At BaySystems, all activities concerning quality, safety and environmental protection are integrated in a single global management system.
With over 4,000 employees at more than 20 sites, we offer every polyurethane processor – irrespective of size or specialization – optimum solutions, technical advice, quality service and polyurethane systems. Why not harness these resources to ensure your company’s future business success?
BaySystems produces Bayblock™ (acrylics) that are water-based elastomeric coatings and Bayseal™ (Spray Foam) widely used in BaySystems roofing systems for most roofing substrates. The Bayblock™ (acrylics) are also tyically used as “cool” roof coatings over various roof surfaces. They have earned high CRRC® ratings due to their high reflectivity of harmful UV rays.
This specification covers coated sprayed foam roofing and includes Spray Polyurethane Foam (SPF) Insulation Roofing and Bayblock Acrylic and Baytec™ Sil Silicone Coatings products. Bayseal™ Spray Polyurethane Foam (SPF) Insulation Roofing, when used with these elastomeric coatings, creates a complete roofing system that insulates, protects, stops leaks, adds structural support to the building, and cuts the amount of radiated heat into the building, thereby cutting energy costs.
