When Thermal Specialties Inc. was established in 1981, its
founders knew the company would succeed at designing, building
and repairing commercial furnaces if they did one thing: keep
their word.
It is that word — our commitment to on-time service
and superior workmanship — that has helped TSI forge
a decades-long bond with customers in the south central United
States. And it is that word that has helped us grow not only
our refractory business, but also our three other company divisions.
The family of TSI companies work together seamlessly to provide
the precise combination of heat-related products and services
that commercial and industrial clients demand. This website
introduces you to each of the four company divisions, giving
you a broad view of the capabilities represented by Thermal
Specialties Inc., Allied Insulation Company, TSI Heat Treat,
and
TSI Fireproofing and Fire Stopping.
