Since its inception, the company has relied ona network of its own design offices and subcontractors, each with theirown specialty. Inspiration, design and innovation are born in our Italian branch, where the first models, preliminary tests and part of the production are made.

Quality control

Our products require careful control and support of the human factor, hence the decision to partially manufacture in Italy, where "handmade" is synonymous with the highest quality and a guarantee for the final customer.

Among our outstanding products, one of the best sellers is BLINDOFINESTRA. This is the only so far line of burglar-proof PVC windows available on the Polish market, which have the RC3 certificate of the prestigious IFT Rosenheim institute.

Windows from RC4 to RC6 class, on the other hand, are manufactured from aluminum and steel.



An interesting feature may be the Blindofinestra line in the PANZER FENSTER version, in which we install BR5.NS class glass with a special polycarbonate partition as standard.

Panzer series windows and doors are recommended not only for housing,
but also for prestigious stores and government buildings.

The range of our anti-burglary products is completed by special blinds, grilles, partitions and shutters. All rigorously tested from class RC3 to RC5.
