Achieve High R-Values in New Construction and Retrofits with OPTIM-R E

May 5, 2025
This rigid vacuum insulation panel is sealed in a gas-tight envelope for more durability and less risky handling.

OPTIM-R E by Kingspan Insulation North America is a rigid vacuum insulation panel with a fumed silica core that’s encased and sealed in a thin, gas-tight envelope. The industry’s only encapsulated vacuum insulation panel, it delivers low thermal conductivity, with an R-value of 34.2 per inch at the center of the panel. The proprietary coating increases durability and reduces the risk of handling on site.

OPTIM-R E addresses the growing demand for energy-efficient roofing solutions in both new build and retrofit applications where construction depth is limited. In new construction, it can improve R-values in areas that might otherwise reduce the envelope’s thermal performance; in retrofits, it enables insulation in locations that might have remained under-insulated due to space restraints.
