Opelose? The perfect mix of open and close.

All windows open and close.

Only one can 'opelose'.

With the new, innovative opelose function, Winkhaus is revolutionising ventilation as you know it. Thanks to the activPilot Comfort fitting system, a practically invisible ventilation gap of approximately 6 mm is formed circumferentially between the sash and window frame.

Windows that opelose open wide enough to provide a continuous supply of fresh air, improving room climate and preventing damage from mildew. At the same time, they are closed enough to offer more security, reduce outside noise and improve energy efficiency.

Innovative ventilation

Opelosing is the simple way of providing rooms with fresh air constantly,
and thus an optimal addition to the traditional opening modes of windows.

Closed.

A closed window does not enable any exchange of air. However, it provides increased burglar resistance.

Open.

Open windows bring fresh air into a room very quickly. Brief and intensive ventilation allows for an efficient exchange of air. It goes without saying that burglary protection is not possible if windows are open.

Tilted.

Tilting a window is a popular method of letting fresh air into a room. However, tilted windows cannot provide sufficient protection against draughts. What is more, this window position does not provide any burglar resistance.

Opelosed.

Opelosed windows enable a continuous exchange of air. At the same time the burglar resistance is identical to that of closed windows and draughts are avoided. For that reason opelosing is a secure alternative to the tilt position.

Trouble-free ventilation.

Effective ventilation, even when you’re not home - opelosed windows move the sash roughly 6mm away from the frame. This means they are sufficiently closed to offer increased burglary protection up to RC2.

No more mildew!

Mildew within your own four walls is now a thing of the past. Opelosed windows are open enough to allow a continuous stream of fresh air, which maintains a healthy indoor climate and can thus effectively prevent mildew from forming.

Save energy when airing.

Fresh air without an extreme drop in temperature means lower energy consumption. A simple calculation which works well thanks to opelosed windows.

Insects stay outside.

Keep insects out at any time of day or night. Opelosed windows move the sash roughly 6mm away from the frame. Flies and mosquitoes barely have any chance of getting into the house through this narrow ventilation gap.

Simply flexible

Our activPilot Comfort PADK is the fitting with turn, tilt and opelosing functions and is so flexible that it is suitable for any field of applications. It can be used for both timber and PVC-U windows and offers similarly good burglary protection when opelosed as a closed window does.

Special solutions

The activPilot Comfort PADS fitting system can even be installed in special spatial circumstances. In fact, special windows such as round arch, studio and triangular windows can be opelosed just as conveniently as rectangular windows can – thus providing healthy ventilation for the entire house.

Smart ventilation

Opelosing fittings can be integrated perfectly in your smart home. And they can be equipped with a motor drive and radio contacts. This allows windows to be controlled at the push of a button, via remote control or even with a programmable ventilation system.

Easily accessible

The activPilot Comfort PAD fitting system offers the option of conveniently opening or opelosing the window from a seated position. This makes it the perfect solution for hard-to-reach windows and low-threshold doors, e.g. in senior living environments.
