Our projects


Open MAX Premium is an innovative modular system which works uniquely; its secret is in the name itself, each shutter is placed and slides independently, transforming spaces between the rooms or in the entrance to the garden or terrace.

Unlike the traditional folding system, Open MAX goes unnoticed inside, creating wide and open spaces. Its unique system allows each shutter/ door to open independently, facilitating cleaning and ventilation.


Design and technology united for greater energy efficiency

Legend incorporates a third central closing joint with 6 chambers in 90 mm sheet and 5 cameras in 76 mm frame, making it the most advanced and highest performing solution on the market. Its architectural design, based on straight lines provides a stylized final result for windows and doors.


Design and technology united for greater energy efficiency

The Legend Parallel slide allows you to close large spaces through a refined system of parallel sliding doors which guarantees all the insulation features. When the handle is operated, the door moves slightly inwards to allow for smooth and effortless sliding. Once closed, the door is secured thus guaranteeing maximum comfort in the room.


iSlide-NEO is the sliding system highlighting the positive points of insulation and rigidity of continuous fiberglass. With Thermofibre Deceuninck's new sliding system, and iSlide-neo, you can now have access to the market benchmark since we are offering 2 to 3 track systems with the possibility of up to 6 shutters/doors.
