Opal

PVC windows - rebated outside and inside

The reliable entry-level window for a small budget

The Opal 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 - for the tried and tested, classic look

Connection of individual elements

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.

SURPRISINGLY EASY TO CLEAN

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

SPOTLESSLY CLEAN

A concealed drainage provides a flawless look without slots, millings on the frame or yellowed cover caps. Water stains have no chance and cleaning is made much easier.

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 windows & patio doors

Opal windows & patio doors

The windows and patio doors of the Opal line are rebated outside and inside. The familiar design fits both new buildings with a classic character and renovation projects where the original charm is to be retained.

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 AND STRONG

Floor-to-ceiling windows and patio doors are exposed to rough 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 lift-and-slide door

[Translate to Englisch:]

Opal 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 lift-and-slide door combines the proven material PVC with the modern state of window technology.

Note

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.

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.
