Triangle is one of the nation’s leading insulation experts. We offer insulation engineering, fabrication and installation services, as well as material sales. Triangle has an excellent reputation for meeting critical construction schedules.

Our extensive experience in the demanding, schedule-driven industrial market includes: construction and maintenance at power facilities and substations, including: fossil fuel, co-generation, hydroelectric, combustion turbines, steam turbines, and nuclear facilities. We are also experienced in dust control systems, catalytic reduction units (SCR), and flue gas desulfurization (FGD) projects.

We also provide insulation, HVAC, sheet metal and scaffolding services at ethanol, coal gasification, biodiesel, and emerging alternative fuel facilities. We routinely work at chemical, petrochemical, manufacturing, and paper/pulp facilities. Additionally, Triangle has worked extensively for the U.S. Dept. of Energy, Tennessee Valley Authority, NASA, U.S Army Corps of Engineers and many others.

We utilize all types of insulation determined by the specifications and application of each project, including:

  • • Fiberglass
  • • Armaflex
  • • Foam Glass
  • • Mineral Wool
  • • Calcium Silicate
  • • Styrofoam/Urethane
  • • Perelite

We have the ability to fabricate foam glass pipe covering from block in our fabrication facility, which saves our customers money.

Whether it’s removable custom insulation blankets, pipe covering, tank or pipe wrap, duct liners, or duct wrap, for special applications, Triangle does it all.

  • • Economic Thickness Analysis
  • • Specification Assistance
  • • Elevated Temperature and Cryogenic Applications
  • • Lagging
  • • Removable, Custom Blankets
  • • Plumbing, Heating, HVAC, Refrigeration, & Other Commercial Applications
  • • 3E Plus Energy Audits and Thermal Imaging Analysis

Insulation Deficiencies can be Hazardous

For optimal operation, industrial facilities such as power and chemical plants require mechanical insulation on pipes, ducts, tanks and equipment.  Insulation controls temperature variation to limit heat transfer from affecting critical processes and elevating the temperature of the immediate environment.  Triangle can help specify appropriate insulation, thicknesses and jackets to manage heat transfer and heat exposure in industrial environments.  This will cause processes to operate more efficiently, protecting personnel from the harm of both direct (burns) and indirect (heat exhaustion) exposure to excessive heat.

Specifying the best mechanical insulation begins by asking a few simple questions and understanding the system demands and how it affects the surrounding environment.  The basic answers required are simple:  the operating temperature, ambient temperature and the design criteria fro the system.  The design criteria may be personnel protection driven - keeping the outside diameter temperature below a certain temperature to protect personnel or sensitive instruments, it may be heat gain driven for condensation management to prevent moisture hazards (slippery floors, mold, mildew, etc.) or it may be driven by a maximum heat loss to keep the system operating at the highest efficiently possible. 

Knowing if the system is outdoors or indoors allows a jacket specification selection appropriate for insulation protection preventing damage from weather and environmental chemicals that will ensure long lasting insulation protection.

Triangle has the expertise and experience to provide guidance in navigating you to the best insulation system (insulation and jacketing) for your particular minimizing hazards to power and chemical systems, surroundings and personnel.
