As effective as they are sustainable

We use Airwalls to separate air to control temperatures, save energy and keep out unwanted elements such as odors, moisture, dust, gas, viruses or bacteria.

Thermal Insulation

We protect doors and gates against heat loss, especially against cold draughts

FAQ

What is an airwall and how does it work?

Airwalls are systems that accelerate air to high speeds with the help of fans and compress it into a thin jet via a patented nozzle (pressure linear module). The generated air jet prevents layers of air from mixing. Our units can be mounted on the side of gates or above doors. The air jet then separates the air over the entire height. This keeps cold air outside in winter, for example, and does not cool the air indoors. Airwalls are modular and therefore have a lot of planning freedom. They can therefore also be retrofitted without any problems.
