The Demilec Inc. Story

How Our Legacy Began

In 1983, Demilec opened operations on the North Shore area of Montreal, Canada. Our 80,000 square foot research and manufacturing facility began the Demilec story.

In 1997, Demilec expanded operations into the U.S. (Dallas, Texas) by establishing a research, development, and polyurethane manufacturing plant. In order to meet aggressive market demands, in July 2014, Demilec opened a new state-of-the-art facility in Arlington, Texas, designed to optimize U.S. production in its laboratories and manufacturing plant. With both the U.S. and Canada manufacturing our products, as well as sales representatives throughout North America, Demilec serves customers both locally and globally in commercial, industrial, residential, and agricultural construction.

What We Develop. How We Achieve Results. How We Measure Progress.


Demilec is a forerunner in the development of innovative technology and advanced science to create a line of open-cell and closed-cell spray foam insulation and coating products. During the past 30 years, we have established a widely-recognized reputation as a leader in the polyurethane field for our unsurpassed quality and performance of our products, supported by superior service. In addition, Demilec has seen continued growth year after year, which has provided jobs for the economy, while we continue to develop products which decrease the demand for fossil fuels worldwide.


Our spray foam insulation and coating products make commercial, industrial, residential, and agricultural buildings more energy efficient by providing high R-values, utilizing some of the highest recycled and renewable content commercially available, and sealing areas to create barriers against outside air, moisture, vapor, and noise pollutants.


In addition to building our new facility in July 2014, our employee growth from when Demilec began in 1983, went from five employees to more than 150 employees between the U.S. headquarters and the Canadian office and manufacturing plant.

Since the Demilec plant is fully-automated, this means it takes fewer people and less manpower to produce the same amount of product a non-automated plant would produce.

From the corporate and administrative leadership to the chemical development group, we have also continued to grow by evolving our processes and procedures, which allow us to provide better service and produce higher quality products. The chemists in the U.S. work in collaboration with our Canadian chemists when developing product formulas and partner together using innovative science to maintain Demilec's standing as an industry leader.

Commitment to Helping Our Environment

In October 2014, Demilec hit a milestone – we recycled our 300 millionth plastic bottle! That's 300 million plastic bottles which would have ended up in landfills otherwise!

Our tireless efforts to use renewable and recyclable content in our products have been significantly recognized by various organizations.
