Carlisle SynTec Systems has introduced ThermaThin 7™, a new polyiso insulation solution that delivers R-7 per inch for commercial roofing applications. Compared to standard polyiso insulation at approximately R-5.7 per inch, ThermaThin 7 helps project teams achieve thermal performance with less insulation thickness. The thinner profile helps reduce roof assembly height and offers greater flexibility around rooftop details, transitions, tie-ins, and code-driven R-value requirements.
ThermaThin 7 is especially relevant for cold storage and refrigerated facility applications because its thermal performance increases as temperatures drop. At 25°F, the product delivers approximately 36% higher thermal performance compared to conventional polyiso insulation*. This innovative feature helps support more stable interior conditions, lower refrigeration demand, and achieve long-term operating cost savings in temperature-critical facilities.
Its thin format also benefits jobsite logistics and project execution. An R-30 assembly can be achieved in just 4.3 inches with ThermaThin 7 versus 5.2 inches with standard polyiso insulation, reducing roof profile by approximately 17%. With less material volume required to achieve thermal performance targets, it helps simplify product staging, handling, and coordination for roofing crews.
ThermaThin 7 is designed for compatibility with a range of single-ply commercial roofing systems and features ReadyFlash® technology, a dual-sided facer that allows installers to influence adhesive flash-off times by selecting the appropriate facer side based on jobsite conditions. Plus, with an HFC- and HCFC-free formulation and up to 34% recycled content by weight, ThermaThin 7 can support sustainabilitygoals and contribute to LEED® and Green Globes® certification efforts.
“Roofing teams are being asked to do more with less space, especially on projects where roof height, details, and energy requirements all have to be balanced,” said Julie Eno, vice president of marketing for Carlisle. “ThermaThin 7 gives project teams a practical way to get R-7 performance in a thinner assembly, while also helping address the demands of cold storage and refrigerated buildings.”
ThermaThin 7 expands Carlisle SynTec Systems’ portfolio with an innovation-led insulation solution engineered to support advanced thermal performance and system design flexibility and was recognized at the 2026 International Roofing Expo (IRE) Innovative Product Awards, where it received both the People’s Choice Award in the Siding & Insulation category and an Experts’ Choice Award.
