Topas

PVC/Alu windows - flush on the outside, rebated on the inside

Modern in design, slimmer in budget

As an entry-level model, Topas flatters even lean budgets without compromising on the exterior look and warmth.

Design line Modern

Flush finish outside

The Topas line is flush with the glass and frame on the outside and is therefore ideal for modern, linear architecture.

slightly rebated inside

Topaz is slightly rebated on the inside. The window sash without glazing bead not only looks beautiful, it is also easy to keep clean, as the construction does not require any additional joints on the frame.

Corner connections - nice and 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.

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.

SURPRISINGLY EASY TO CLEAN

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

THERMAL VALUE PATENTED

A patented profile structure inside the window ensures maximum heat values and additional reinforcement of the frame.

Topas windows & patio doors

Topas 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

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.
 

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.
 

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

Topas Fixed Parts

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.
