The type and quality of mechanical insulation play a key role in decreasing a facility’s carbon footprint, cost of operation and project performance.  At Triangle, we ensure your mechanical insulation systems will benefit both the environment and our project and facilities. 

Our experts offer insulation, fabrication, installation services, and material sales for all types of insulation. They work in industrial spaces along with hospitals, schools, retail businesses, medical complexes, office buildings, arenas, and many other facilities.


Triangle is an industry pioneer and innovator in energy conservation with over 40 years of experience in the removable insulation blanket marketplace. EnergyArmour blankets are designed to be completely removable and replaceable, but they still fully conserve heat and reduce sound.

Our professionally designed, custom fabricated blankets are most commonly installed on items such as flanged pairs, flanged valves, strainers, pumps, root valve assemblies, gauges, compressors, turbines, exhaust systems, equipment body flanges and heads. Triangle experts also custom fabricate blankets for any configuration or size, from tanks down to intricate instrumentation assemblies.
