 The profiles of the IDEAL 4000 series combine advanced technology with the highest level of user comfort.

The IDEAL 4000 system is a 5-chamber profile with a 70 mm installation depth, equipped with external seals and capable of integrating glazing units up to 49 mm thick. Thanks to its solid construction and steel reinforcements, these profiles offer excellent static properties, allowing for the creation of large windows.

The IDEAL 4000 series allows for the use of wider, energy-efficient glazing units, ensuring excellent thermal performance. The flat sash shape gives the windows a modern and elegant appearance, ideal for original interior designs.
