Topas
Now even slimmer! The budget-friendly uPVC/aluminium window with flush frame and glass design. For a contemporary look with an accent inside.

Flush surface and glazing on the exterior

Topas is exceptionally flush-mounted on the exterior. The seamless alignment with the glass pane gives the window a refined appearance, emphasizing the clean and elegant architecture of your home.

Offset on the interior

Topas is offset on the interior and features a beadless design. Combined with its slightly beveled window edge, it creates a contemporary look with an intriguing sense of depth.

Exceptionally slim

Less frame – more daylight. Over 12% slimmer compared to similar current window systems.

Sustainable PVC

Using 80% recycled PVC, we focus on sustainability without compromising quality or design. The surface is radiant white and made from virgin PVC.

Simple and contemporary

The beveled sash design on the interior looks contemporary and blends perfectly with simple, modern interior styles. Matching handles further accentuate this look.

SURPRISINGLY EASY TO CLEAN

Effortless cleaning thanks to easy-to-clean profile contours without a dirty joint.

Renovation-friendly constructed

Renovations are usually a major intervention in the façade of the house. Topas counteracts this, as it can be installed with a slimmer system thickness even in older houses with narrower outer walls.

Less Frame
more beautful windows

Topas offers frames that are over 12% slimmer compared to similar current window systems.

Your benefits

+ More daylight and brighter living
+ Better views
+ Increased solar heat gain – saving you heating costs in winter
+ Enhanced comfort for you and your family

Windows & patio doors

The Topas line skilfully combines design and technology and offers all the advantages of modern PVC/Alu windows and patio doors at an attractive price. 

DETAILS MATTER

LARGE DIMENSIONS

Patio doors are available up to a maximum height of 2.7m. This height is possible due to an innovative positioning of an additional steel reinforcement in the profile.
 

COUPLING

Stable, narrow couplings and mullions paired with extremely slim pilaster strips for high structural requirements.
 

BARRIER-FREE FLOOR THRESHOLD FOR PATIO DOORS

The 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 colours.
 

PULL HANDLE

Functional and aesthetic - the swivel-mounted pull handle designed by Josko. So slim and flat that it easily fits under an insect screen sliding frame.

Topas Fixed Parts

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.
