Product details
One frame family. Different openings.
View full size COR 70 Industrial is a useful starting point when an elevation needs different window functions with a coordinated aluminium appearance. The range includes inward- and outward-opening arrangements, allowing room use and access to shape the design.
Its broad glazing capacity gives space to consider thermal or acoustic glass and, where the final configuration permits, triple glazing. Concealed drainage and hardware options can refine the visible detail.
