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.

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.

Increases burglary deterrence through special mushroom cam locksto stop the window sash being pushed out of the locking mechanism

The Regel-Air ventilation system is a self-regulating system that is installed in the upper section of the window and can be retro-fitted if required. Fresh air supplied from the outside flows laterally over the narrowing seal in the window rebate. In normal operation the preheated air then rises preheated between the sash and the frame through the ventilator below the ceiling into the room. In stormy weather or strong winds the system automatically stays closed, thereby preventing draughts. The Regel-Air has a flow rate of 2.1 m³/h at 4 Pa. Additional benefit of the window rebate ventilator: It shuts out noise, the device can achieve high acoustic insulation values up to acoustic protection class 4 (= 42 dB).

Windows used to be tilted or opened all the way to air out a room. With the innovative Safe&Go ventilation system the top of the sash can be positioned 10 mm from the window frame. What’s special about this is that the window is locked on all sides when in the ventilation position. A basic level of ventilation is provided, but with the burglary deterrence of a closed window. Thus you can safely air out the room and do your errands at the same time. 

Makes it difficult to lever the window open with special mushroom cam locks placed at the corners of the window. Recommended for town houses and terraced houses.

Improves the protection from break-in attempts through additional mushroom cam locks placed around the edges of the window. Recommended for detached homes.

Provides exceptional protection from break-in attempts through the numerous mushroom cam locks placed around the edges of the window. RC3 is the highest security class for windows and is recommended for remotely situated houses, villas and high-value properties.

Multiple locks bolted into special steel reinforcement elements maximise the window’s resistance to being pried out and ensures additional loading capability and stability of frame and window as load-bearing components are genaerally screwed into the steel.

The self-locking handle prevents the hardware from being pushed up.

Prevents window sash slamming shut from gusts of wind by securing the sash in place and enables variable window opening control.

Standard handles are sufficient for windows on difficult-to-access upper floors, but ground floor windows should be fitted with burglar-resistant handle versions.

Optimises the thermal efficiency of the profile system through a clever chamber geometry paired with thermally insulating foam, reduces thermal bridging through full-perimeter foaming even in corner area of profile and ensures a feeling of well-being with consistent glass and surface temperature.

The ‘prestressed’ glass is tougher than conventional insulating glass. Already at a thickness of 8 mm the pane is ‘ball-proof’. However, if the pane is acutually destroyed, it breaks into blunt-edged fragments. Toughened safety glass thus provides dual protection: against forceful impacts and against injuries.

Provides for fresh air in any weather. Air supplied from the outside flows upwards via recessed seals in the rebate and enters the room pre-heated via the special seal. In strong winds the seal pushes against the opening gap to restrict the amount of air flowing in. So even in this situation, basic ventilation is guaranteed and draught effects are avoided. With a fully open seal the system achieves a volume flow of 2.9–3.2 m3/h at 4 Pa. Even when the window is open the ventilation system is not visible either from the outside or from the inside. Weru-Air Comfort achieves high acoustic insulation values up to acoustic protection class 4.
