SpecTips - Why risk your reputation with EPDM splice technology that hasn’t stood the test of time?
Carlisle’s SAT EPDM features time-tested and trusted splice technology with 30 mils of Factory-Applied Tape™
The reliability of EPDM seams was once considered to be a weakness of these roofing systems. This dates back several decades when the industry was using Neoprene or Butyl liquid-applied splice adhesives.The evolution to double-sided splice tapes,and later to factory-applied splice tapes, has transformed EPDM seaming into one of the most reliable and user-friendly splicing systems on the market today. Factory-applied tapes and seam tapes have a proven track record of 20+ years of performance in the field. While technology continues to evolve,it is wise to use a degree of caution when specifying EPDM systems to avoid reigniting any negative perceptions about EPDM seams.
Carlisle’s EPDM membranes use time-tested and trusted splice tape technology. Our SAT EPDM comes with 30 mils of butyl-based splice adhesive that is factory-laminated to the membrane. The thickness of the tape is designed to seal small voids created by step-offs from uneven insulation joints, wood nailer transitions,or metal fastening plates. The butyl-based nature of seam tape is water-insoluble, eliminating the need for Lap Sealant.

CSI 3-Part Specification -07 5323 EPDM -Part 1 Quality Assurance
- Adjoining sheets of self-adhered EPDM shall be spliced together using factory-applied synthetic rubber splice tape that is a minimum 25 mils thick to account for sealing step-offs and uneven substrates.
- Factory-applied tape shall have a minimum 10 years of proven field experience.
- End laps shall be sealed with pressure-sensitive cured or semi-cured 6”-wide flashings that are a minimum 90 mils in total thickness and feature a 30-mil-thick layer of seam tape.
