The HELLA trav plus is characterised by improved heat and noise insulation features and in combination with its easy to install construction it has become the favourite on construction sites. Guaranteed safe fixing of the plaster, defined limit stop positions for the window and no additional formwork speak for the box system that can satisfy the highest demands.





Individual solutions

Every building has its peculiarities Whether the window follows a curvature or has the shape of an oriel: the HELLA box system makes almost any variation possible, since the TRAV can be designed individually. Hence, there are no limits to architectural possibilities.
