Flameless solutions for SBS-modified bitumen roofs have been around for some time, but recent advancements in technology and a more diverse product offering have made them suitable for various roofing types.

In the past, hot asphalt and torch application methods were more popular for SBS-modified bitumen low-slope roofs due to the long curing times, odor, and high VOC content of waterproofing membrane adhesives. However, the manufacturing processes and composition of self-adhesive and cold-applied products have significantly improved, leading to increased interest in their use.

Benefits of Flameless Solutions for All Building Types

The evolved flameless solutions offer numerous advantages:

  • Adaptability: Suitable for all building types, including hospitals, historic buildings, schools, airports, and food facilities
  • Safety: Reduced risk of fire and burns, as well as lower VOC emissions for worker health
  • Compliance: Tested and meeting Canadian Standards Association (CSA A123.21) standards
  • Cost-effectiveness: Lower project costs and insurance fees due to the absence of open flames or hot kettles
  • Environmentally friendly: Reduced air pollutant emissions
  • Faster installation: Time savings with self-adhesive flameless systems, as they require fewer materials and eliminate waiting time for hot kettle preheating
