Thermafiber manufactures and customizes mineral wool insulation for commercial buildings, industrial applications and residential construction. We specialize in high-rise construction - that's why we developed Thermafiber Insolutions™, a systematic approach to help you precisely plan and install insulation on time and on budget.
