The VEKAscreen curtain-walling system is centred around an aluminium mullion capable of large spans, while maintaining narrow sightlines and thermal efficiency. All VEKA and Halo 70mm systems can be used in conjunction with the mullion to produce a screen wall.

The system is capable of spanning multiple floor levels. Windows and doors are secured to the mullions with an aluminium pressure plate and PVCU cover/stick system, drained and ventilated. The system has built-in thermal breaks and expansion/contraction elements.
