Performance Comparison
Insulation Comparison Chart
See how ThermBoard® rigid insulation outperforms every conventional insulation method across every key performance category — R-value, fire safety, moisture resistance, and more.
Not all insulation is created equal. The chart below compares ThermBoard® rigid insulation boards against the most common conventional insulation methods used in residential and commercial construction today. The data is based on real-world performance — not laboratory best-case scenarios.
ThermBoard® leads in every category that matters most to builders, contractors, and building owners — higher R-values, non-combustible materials, zero smoke production, and consistent long-term performance with no maintenance required.

Superior R-Values
ThermBoard® delivers up to R-28.5 — significantly higher than any conventional insulation method at comparable thickness. Better R-value means lower energy bills and more comfortable buildings.
Non-Combustible
Unlike spray foam and fiberglass which are combustible and produce toxic smoke, ThermBoard® rigid boards are non-combustible — providing a critical safety advantage in any building application.
Zero Smoke Production
ThermBoard® produces no smoke — a critical safety advantage over spray foam which produces highly toxic smoke when exposed to fire. Safer buildings start with safer materials.
The Choice is Clear
ThermBoard® outperforms every alternative — better R-values, safer materials, faster installation, and lower lifetime costs.
