The new Box Gutter Expansion Joint From Aztec Australasia is focused on assisting all installations for industrial box gutters.
What exactly is an expansion joint?
Box Gutter: A gutter, not at an eave, is typically found at the base of two opposing roof slopes.
Simply stated, a box gutter is terminated with an end cap as if the gutter has ended. Then, a space of an inch or two separates that section of gutter from the next, which begins with another end cap. The space between the pair of end caps is covered with a clamped cap to prevent water entry and to allow the separate sections of gutter to move back and forth with temperature changes because an expansion joint consists of two terminations in the gutter system, it creates a dam in the system, preventing the flow of water across the joint.
An expansion joint, therefore, should be located at a high point in the gutter, as water will then flow away from the expansion joint rather than try to flow through it. When a high point is not available, a drain outlet must be included or added to the gutter system on the uphill side of the expansion joint.Now with Box Gutter Expansion Joint (Rubber type) you can simply install and allow the water to keep flowing
The rubber compound has been developed to allow stretch capabilities ensuring the box gutter when joined can expand and contract when dealing with extreme temperature changes. Due to the Rubber compound having a low profile water can easily flow through the expansion joint.
Standard Box Gutter installations recommend an Expansion Joint every 10 metres. The product is easy to install simply with Rivets and Silicone.
