heroal W 77 i

Block Window System for Maximum Transparency

The block window system heroal W 77 i combines a slim design and maximum transparency with top-grade heat insulation. The outer appearance of the window, its invisible sash ideally emphasizing the slim face widths of the system, and heat insulation values of Uf 1.0 W/m²K (standard average) meet highest architectural and energetic requirements. The filigree design makes the system especially suitable for residential and commercial construction. The concealed system fittings heroal WF 100 I in particular enhance the elegant design.

The future-proof aluminium compound system is available with conventional inner glazing; its elements serve a number of purposes, including the use as curtain wall insert elements.
