French manufacturer of custom-made thermal insulation blankets — Made in France
At Calomatech, every project is much more than a simple technical service: it is the meeting point of industrial innovation, human know-how, and sustainable commitment.
We design thermal insulation solutions and install them for our clients: industrial sites, commercial and residential buildings, district heating networks, and marine environments such as ships.
The production steps of a Calomatech insulation blanket
8 years of expertise in industrial sewing
Our insulating blankets are custom-made in our workshops in Normandy, France. Nothing is left to chance: we take into account the shapes and the environment in which valves, equipment, piping networks, and installations operate: constraints, space limitations, tie rods, cable trays, branch connections, and more.
For more specific components, our engineering department develops insulation blanket designs using CAD software, where they model our clients’ requirements in 3D.
