In addition to classic aluminium doors, we also offer automatic, sliding and swing doors. The top quality materials and proven production technology make Nitus aluminium joinery not only fashionable, durable and extremely resistant, but most of all safe. Our aluminium doors also provide excellent thermal and sound insulation. As a leading manufacturer of entrance doors, we offer our clients only durable and innovative products that match the requirements and trends of modern architecture.
Cold doors
The aluminium cold door system is used for interiors that do not require thermal insulation. Its structure is light, durable and functional. It is intended for designing sliding doors, swing doors, partition walls or cash desks, as well as various types of structures at any angle. Aluminium internal doors are manufactured of an aluminium profile system without a thermal break. The door leaf can be filled with a single-chamber or double-chamber glazing unit or an aluminium sheet panel. Groove and surface hinges can be used with the system.
Warm doors
The warm aluminium door system is suitable for designing external doors, windows and various displays. It achieves high thermal insulation parameters through the use of special thermal inserts. Multiple glazed panels – single-chamber, double-chamber or smooth glazing units are an excellent solution for the leaf infill. The heat transfer coefficient of the aluminium entrance doors meets the current requirements and those that will come into force in 2021 (Ud of min. 1.1 W/m2K). A wide range of profiles guarantees the required aesthetics while ensuring the structure strength. Due to the availability of several systems, modern doors with very high functionality can be designed. A wide range of glazing units makes it possible to use various types of glass panes – one- and two-chamber, acoustic or burglary resistant.
