Product Applications
This box gutter is commonly installed along parapet walls or at roof boundaries, especially where heavy rainfall is a factor. With its 150 x 150 profile, it is an excellent option to suit both residential homes and large-scale building projects. The purpose of this design is to efficiently direct water away from the building and protect structural elements. Its clean, rectangular design complements modern roofing designs and can be seamlessly integrated with COLORBOND® roof flashing systems. When installing, it is important to consider the angle at which the flashing is placed to ensure proper water runoff and long-term durability. The design also addresses the possibility of water spillage into the roof space, aiming to minimize this risk through careful engineering.
