For more than five decades, Dover Insulation has provided quality and cost-efficient mechanical insulation services for commercial and industrial applications. Mechanical insulation is essential to industry and construction, as it is important for energy conservation, freeze protection, personnel protection, mold prevention, condensation control, process control, noise control, and fire safety. Dover Insulation sets the industry standard in workmanship, as a contractor of industrial, commercial, and institutional insulations, a fabricator of removable (reusable) insulation systems, and as a direct factory distributor for manufacturers of quality insulation materials.

A family-owned business in its third generation as mechanical insulators, Dover Insulation takes pride in offering superior work and impeccable customer service. Our mission since 1965: first-class work on schedule and exceptional value and customer service, regardless of the size or scope of the job.
