The VEKAVARIANT EPS Grupor insulation box expands the product portfolio in the area of top-mounted roller shutter boxes. The insulation box meets the highest requirements for thermal and sound insulation and is ideally suited for new buildings and core renovations. Fabricators benefit from a high degree of efficiency, because with VEKAVARIANT EPS Grupor the familiar processing steps and components of the established top-mounted box system are largely retained. Convenient clip technology connects the box to all VEKA window systems as well as all common systems from other system providers - including aluminium or wood.
