heroal W 72

Flexible aluminium window system for every field of application

The aluminium window system heroal W 72 is the all-rounder of heroal’s range, offering highest functionality and flexibility for every field of application. The unique break geometry and a 100% filling of the insulation chamber guarantee best insulation values, while the face width of only 72 mm provides for a filigree look. As a result, you can save heating costs in winter and energy for air-conditioning your rooms in summer. While a minimum protection of class RC 2 is recommended by the police, heroal W 72 offers you certified burglary resistance up to resistance class RC 3. This increases security for everything that is dear to you.
