Saving energy used to heat and protecting the environment are the challenges of the day. But protecting the environment already starts with production. The Platin Passiv frame, for example, is made using timber from sustainable forests. Platin Passiv is simply Passive-House technology that looks great.

Something
special

Passive House certificate

Platin Passiv has been awarded the Passive House certificate from the Passive House Institute in Darmstadt, Germany, which was set up by Dr. Wolfgang

Unique fitting evenly with the glass externally

A Josko specialty: Rebated by only 3 mm between the glass and frame - with a modern design, the window can practically be cleaned with a simple wipe!

Even with frame

All our modern window systems are externally even with the frame and glass, which follows the trend towards architecture with clean lines.

NEW! Flush windows with glazing bars

From now, available with 9 mm glass recess outside – this allows for an elegant combination with 25 mm slim glazing bars.

Exclusive gluing as standard

No multi-layer gluing or joint visible on the sash which contributes to an especially slim look with a continuous wood grain inside.

Three-layer solid wood construction

This contributes to a higher stability against the wood’s distortion; thanks to the exclusive design it is not visible on the frame.

Wood from sustainable forests

Our wood comes only from sustainable, managed forests. Spruce, oak and larch are sourced locally

The beauty is in what you don't see.

Extremely slim frames with clean lines, uncluttered by glass strips and joints, for both windows and terrace doors.

Platin – even with the frame internally

The Platin series not only fits evenly with the glass and frame externally, there is also no rebate between the internal and external frame on the ins

Surprisingly effortless to look after

Horizontal surfaces on which dirt can settle are largely avoided outside - making the windows surprisingly effortless to keep clean.

NEW! Perfect look through rebate joints

The rebate joint for Platin frame glazings is now milled from one piece. The inserted bar can be omitted.
