System Decalu 94 retro is one of the warmest aluminium systems in our offer. It is intended for the production of windows that are similar to retro wooden windows. It is a combination of modern solutions with a classic look. Windows made using this system are equipped with muntins, which are most often used in wooden windows.

Windows in the Decalu 94 system can be made using a fixed post or a movable post. In the case of the second option, the user will be able to enjoy the full light after opening the window.

Both fixed posts and muntins look like frame profiles and sashes. Additional advantages that give joinery an aesthetic look are hidden hinges, invisible gaskets and invisible dehydration.
