Opal Alu

PVC/Alu windows - rebated outside and inside

Classic look - Modern technology. Proven for 20 years.

The Opal Alu product line is harmonised and offers all common opening variants - windows, patio doors, Fixed Parts and sliding doors.

Design line Classic

REBATED LOOK OUTSIDE

Window frame, sash and glass are rebated. The familiar look relies on modern Josko technology and gives depth to your house architecture.

Rebated look inside

Window frames and sashes are also rebated on the inside and thus contribute to a cosy living experience.

New corner connections - very easy to clean

Instead of the usual U-shaped, wide and angular recessed corner connection joint, Josko PVC standard windows are designed with a V-shaped, delicate and easy-to-clean design joint.

SURPRISINGLY EASY TO CLEAN

Effortless cleaning due to easy-to-clean profile contours.

DECORATIVE FOILS

With the decorative films from Josko you give simple PVC windows an individual (wood) look on the inside.

COUPLING

If windows are connected to one another in order to maximise the glass area, this is usually unattractive because the frames look very bulky. Our window couplings are designed in such a way that they are beautifully slim and yet meet a high degree of structural requirements.

Proven economical

Opal impresses with its outstanding heat value and helps to significantly reduce heating costs.

Suitable for passive and low-energy houses at a good price/performance ratio.

PVC

When buying a window, make sure that the PVC is free of lead and cadmium. PVC waste is used for the production of PVC. This has been standard at Josko for years.

Opal Alu windows & patio doors

Opal Alu windows & patio doors

The windows and patio doors of the Opal Alu product line offer current living trends and clear design for a small budget.
A highly weatherproof aluminium shell protects the elements on the outside and makes them durable. 

 

DETAILS MATTER

GLAZING BAR OPTIONS

For Opal, several glazing bar options are available. No matter if placed on the in-or outside or in-between panes - glazing bars create a comfortable home.
 

BARRIER-FREE

Floor-to-ceiling windows and patio doors are exposed to high weather conditions. The barrier-free Isostep threshold does not give even large amounts of water a chance. Thanks to good thermal insulation, the interior remains particularly comfortable. Available in many colours on request.
 

Opal Alu lift-and-slide door

Opal Alu lift-and-slide door

Lift-and-slide doors are also popular elements in classic architecture: They open the view to the outside and create generous transitions. The Opal Alu lift-and-slide door combines the tried and tested materials PVC and aluminium with the modern state of window technology. 

DETAILS MATTER

BARRIER-FREE THRESHOLD

The Isostep threshold has an especially high heat insulation due to the GRP fibre reinforced PVC and is also designed with a high resistance to driving rain. New! Available in many different colours.

EVEN SLIMMER VISIBLE WIDTH

The new Opal lift-and-slide door offers even more transparent freedom now.
 

Slim guide rail

Aesthetics in every detail of Josko products. The upper guide rail is slim and elegant.
 

Opal Alu fixed units

Opal Alu fixed units

Fixed parts - i.e. elements that cannot be opened - are either coupled with a lift-and-slide door or a window or create beautiful views on their own.
Together with patio doors, they form a contemporary all-glass system that meets today's living standards.

sun shade

When modern architecture leads to larger window areas, elegant sun and privacy protection solutions are becoming increasingly important. These provide plenty of shade during the day and ensure that the temperature inside the house is balanced in summer. In the evening they primarily hold off curious glances.

With Venetian blinds and roller shutters, Josko offers you the ideal solution that is coordinated and well thought-out as an integrated overall system. No visually unsightly handicraft solutions from different manufacturers, no coordination of multiple contacts, just Smart Mix.
