Climawin--Schematic-House--no-textClimawin is both a window and a fresh air ventilation system.

The System

the-system-exteriorClimawin can save 20%  of your annual energy costs.

Saving Energy


Climawin is an integrated ventilation window system that uses heat normally lost through a window to bring in and preheat fresh air and save energy.

A typical house fitted with the Climawin system alone will reduce its annual energy bill by 20%.

Heat Recovery

Climawin can recover 50% of the heat needed to make outside air comfortable on its way in, and on southern facades this rises to become a net heat gain.

Climawin uses electronically controlled valves and flaps to regulate the air coming in, maximising heat recovery and preventing condensation.

Renovation or New Build

Climawin is ideal for renovation, including widow replacement only projects, and suits new build construction also.


Climawin is self-powered and requires no wiring.

Available Soon

Climawin is designed and produced in Denmark and Germany and will be available throughout Europe in late 2014.
