FITTINGS Comprehensive and individual WERU window fittings

• passive demand-controlled window ventilator for ventilation of closed rooms
• functions by pressure equalisation between outside and inside air (pressure differential principle)
• the regulation of air intake is based on the relative humidity
• via a three-stage controller you can select between continuous ventilation, humidity control and minimal ventilation

Are resistant to temperature, UV- and ageing, absorb dynamic loads and, with a linear thermal transmittance of 0.064 W/(mK), also have excellent thermal insulation properties.

As an extra precaution, families with small children may want to have additional protection against unwanted opening of the window by children. The special tilt-before-turn mechanism ensures that children can only tilt, and not open, the window. The window can only be opened all the way with a key.

Highly insulating PVCu spacer

• reduces condensation on the glass pane above the glazing bead
• ensures a pleasant living climate due to a consistent surface temperature

This hardware component provides for partial ventilation. Arresting the sash with the preset gap of 5 mm stops the window from slamming shut.

Issues an alarm by emitting a loud acoustic signal when the pane is broken and hence startles before break-in attempts. False alarms are prevented by a dual sensor mechanism (vibration and frequency).

Activate your energy-saving potential with WERU windows. Depending on the design situation, we can offer you a variety of thermal protection windows with thermal insulation values of up to 0.5 W/(m²K), so that even the strict energy-saving regulations (EnEV) can be met without any problems.

The glass panes are bonded to an extremely tough, tear-resistant plastic film that not only ensures the glass is very unlikely to break. Even if the pane were to break the fragments would adhere firmly to the film. And even then it would take a lot of time, effort and tools to penetrate the pane. A higher security class can be achieved by increasing the number of plastic films and glass panes.

The lockable handle prevents movement of the hardware and makes it harder to open a broken window by reaching in from the outside. In everyday use it serves as a childproofing means.
