Perfect for renovation

IDEAL 4000 windows are an excellent replacement for old joinery, especially in renovation projects where expanding the window opening is often not an option. The low height of the frame and sash (only 114 mm) maximizes the use of glazed area, ensuring more natural light in the room.

High quality and comfort

The IDEAL 4000 profile series combines modern technology with maximum user comfort. The strong profile construction with a depth of 70 mm and large chambers for steel reinforcements guarantee stability and allow for the creation of large-sized windows. The multi-chamber construction provides high thermal and acoustic insulation, protecting against noise and heat loss.

The IDEAL 4000 system embodies aesthetics, functionality, and comfort. The product is available in a range of classic colors and premium finishes: woodec—decorative wooden structures and aludec—featuring a fine-grained, matte surface resembling painted aluminum.
