heroal W 77 HI

Aluminium window system suited for passive houses

The window system heroal W 77 HI offers you small face widths, and at the same time, thanks to its modern design, achieves thermal insulation values required for passive houses. That means you benefit from lower heating and energy costs and, in some countries, become eligible for attractive state subsidies. Compared to similar aluminium windows suited for passive houses, the heroal W 77 HI stands out for its extremely small face widths. They provide for an aesthetically appealing look and more transparency, and improve the overall impression for your home. Aluminium windows of the heroal W 77 HI range also offer you certified burglary resistance; their resistance class RC3 exceeds the recommendations of the police. For a safe and comfortable home.

  • Suitable for passive houses
  • Filigree design
  • Burglary resistance class RC 3
