The story behind TONZON

TONZON - your reliable insulation partner

.

 

TONZON is the inventor of an insulation technique that uses the air that's available everywhere. The air required for insulation is only trapped in the material at the destination. It's as if we've made the Thermos flask flexible! TONZON is best known in the Netherlands as the pioneer in floor insulation, with its Thermos Cushions. Today, however, dry liners, roofs, radiators and even bathtubs are also being insulated according to the principle of the Thermos flask.

The company

A look behind the scenes

TONZON is, as far as we know, the first manufacturing company to supply all of its own electricity needs. Already in 2016, its solar roof panels produced more power than the company consumed. The rest of the roof is covered with moss. Moss captures particulate matter from the air, limits global warming, and provides a safe nesting site for oystercatchers. A vegetable garden has been created on the factory site, for the staff.

Our vision

An eye to the future

Climate change is an ever-increasing problem in today's world. TONZON is committed to working towards a greener environment in a customer-focused way.

TONZON's products contribute to a healthier living environment. The company aims to install its innovative insulation technology in buildings suitable for the most effective insulation method within the next ten years.
