The passion of colour

Peinture Dumoulin was founded in 1980. At the time, the main activity of the company was making kitchen cabinet finishing.

In 1982, the company took off with the start of painting steel doors.

After a few years, the activities of the company expanded by adding a paint shop of PVC windows as well as, windows and aluminum extrusions.

To meet growing demand, the factory was expanded to 27,000 square feet to accommodate the expansion of our six paint chambers. In total, more than 25 employees are part of the Dumoulin team of the Aluminart group.

Primers that last

Specialist in glazing doors and windows, we use Flexacron™ HR liquid paint, a high-quality, heat-resistant paint. Flexacron HR is an elastomeric polyurethane coating product consisting of a pigmented component and a clear, reactive processing agent. It gradually transforms into a protective film against ultraviolet rays, pollutants, abrasive agents, as well as acid rain.

Flexacron HR has been formulated with highly selective pigments that reflect infrared sunlight. This very special property reduces heat accumulation on the surface of exposed PVC and the temperature remains low enough to prevent warping and discolouration.

This ensures that the color you choose will remain durable and beautiful for years to come.
