Energy efficiency. Classic Craft ® premium entryways contribute to an energy-efficient home. A high-grade polyurethane foam core provides up to four times the insulating R-Value of wood,** helping you save money on energy costs. Trust the experts in fiberglass. We’ve been studying the science of the entry door since 1962 and have turned our experience into industry-leading innovations. Therma-Tru pioneered the fiberglass door in 1983 because we realized that fiberglass was a material that offered superior design and performance characteristics. More than 30 years and tens of millions of fiberglass door slabs later, Therma-Tru has grown to become the leading entry door brand most preferred by builders.* *Brand Use Study, 2022 Builder magazine. **Comparison of fiberglass to wood doors (both without glass).
