    A stylish and reliable Installation for every 74W System

    The 74W System can be provided with 3 rack arms. In 90% of the projects the Standard Rack Arms fulfills the job perfectly, but in special circumstances the "Heavy Duty Rack Arm" or the "Box Rack Arm" are used. Additionally, Sunshield has a broad experience and a large assorment of mounting brackets and methods. With that, a stylish and reliable installation is guaranteed for every blind in every situation. For each project, the Sunshield engineers provide a detailed installation scheme, customized to the specific situation of that project. They are specialized in making the system "disappear" in the mullions, window frames and beams. It is guaranteed that the Sushield system gives an integrated view with the building.

    A wide variety of Colours and types of wood

    Sunshield has many colours in stock. Additionally it is possible to have customized colouring and treatments. It is even possible that louvers, rack arm and plastic components each have a different colour to achieve sophisticated architectural impressions. Western Red Cedar is the type of wood which is advised due to its ability to stay levelled. Custom made colours and structures are possible at request. A overview with most common colours is given below.
