The proven meets the proven - in cooperation with the leading roof window manufacturers.
With the HPG normaline® element you are well advised. We take advantage of the well-known and proven properties of the Roto and VELUX® roof windows and use them to produce complete flat roof elements according to your wishes and ideas. Whether as a single element or as a multi-combination - the choice is yours. Thanks to concealed motors, the openable sashes meet the highest optical requirements. In addition, the elements can be delivered with already mounted external shades and internal darkening systems.
