At the core of the valve is a temperature-sensitive wax encapsulated in a wax thermostat. When the temperature increases, the wax expands and exerts pressure on a small piston.
The technology has been used for years in the automotive industry. It is proven to provide a stable function. The wax thermostat requires no power connection. The windows therefore need no wiring. A wax thermostat is durable and noiseless. We offer a five-year guarantee on LivingBetter window vents.
Our air valves are key to our ventilation window and our complete energy and indoor climate solution. We supply the air vents as an integral part of our window design. Air valves are not available for retrofitting.
Our air valves can also be used in a French window or door if there is insufficient window area in the building.
