Resources

Trufill® provides excellent thermal performance due to a low thermal conductivity and a complete and consistent installation. Trufill® provides a choice of R-Values based on the installed thickness and installed weight per square metre. The stated thermal resistance (R-Value) is provided by installing the required density at the thickness (per the manufacturer’s instructions). Failure to install less than the required density and thickness will result in lower insulation R-Values.
