The Science

EnvelopeSealant TM  offers peace of mind with a 21st century product testing pedigree. Whether you’re an architect, engineer, building science professional or builder you can feel confident knowing EnvelopeSealant TM  not only complies with 2010 NBC but provides a envelope detail system far beyond a basic minimum building code requirements.
EnvelopeSealant TM  system was engineered, developed and tested specifically for the flange mounted fenestration products in all climatic conditions. EnvelopeSealant TM  system was also engineered for compatibility with virtually all building products. EnvelopeSealant TM  system has been applied to over 3 million window or door installation applications.
EnvelopeSealant TM  system is like no other caulking. EnvelopeSealant TM  is very unique in that no other sealant composition or engineering parallels the high performance specification as they relate to the window wall interface as EnvelopeSealant TM.
