WERU Windows

Lift & Slide Doors

outstanding operating comfort and technology

The Weru lifting/sliding door is a space-saving solution which is recommended for extremely large door openings. The precision guidance of the sash at the top and bottom means it can be opened and closed sideways very easily. It also offers effective thermal protection, maximum tightness, exceptional stability and reliable burglary deterrence. The lifting/sliding door already complies with the more stringent requirements of the German Energy Saving Ordinance which will come into force in 2016 and can be equipped with the Weru secur monitoring system if required.

Technical Highlights


High operating comfort
Special steel-reinforced running carriage housings stabilise the sashes, which therefore slide open open and closed sideways very easily due to the smooth-running operation. A special easy access threshold is available on request (to DIN 18040) for an almost seamless transition to outside.

PK1-2-2-1-1-EnergieeffizienzOutstanding energy efficiency
As the 86 mm thick GFP high-tech sash profiles are fully reinforced, the steel reinforcement could partially be omitted thus achieving a Uf value of 1.3 W/(m²K). A Uw value of 0.8 W/ (m²K) is therefore possible with Weru thermal glazing.
PK1-2-2-1-1-BehaglichkeitMore comfort
The ingenious chamber geometry of the PVCu-aluminium bracket ensures outstanding energy efficiency and reduces the danger of condensation forming in the area of the threshold.
PK1-2-2-1-1-WohnkomfortEnhanced living comfort
The special profile construction allows a glazing thickness of 53 mm to be used thus allowing functional glazing to be used to provide a greater degree of thermal insulation, burglar protection and acoustic protection according to the requirements of your living situation.
PK1-2-1-1-1-DichtigkeitOutstanding tightness
Peripheral sash gaskets, special drop- down gaskets and seals on the centre closing profiles ensure outstanding air tightness and effectively keep out driving rain when the lifting sliding door is closed.
PK1-2-2-1-1-StabilitätOutstanding stability
Fully-reinforced GFP high-tech sash profiles ensure outstanding dimensional stability and make sensational sliding sash sizes of 3 m x 2.70 m possible thus admitting more daylight into the living space. The stabilised running carriages guarantee load transfer for heavy triple
glazing systems weighing up to 300 kg
