This pail is clearly the last thing to use to carry water efficiently. And yet, a system as leaky as this one has been draining rainwater from almost all North American roofs for decades. Gutters. As expected, boring holes into this system during installation can lead to leaks and water infiltration during heavy rains. All the conditions are then met for the edge of a roof to rot. Thermal expansion and contraction that stretches out and shortens gutters aggravates this inherent problem by causing repetitive stress on this structure without any expansion joints. Since the nails or screws securing a gutter in place cannot move once they are fastened, such pressure is absorbed by the back of the gutter. As a result, the gutter can lose its watertight seal due to the puncture holes at each anchor point, elongating under pressure up to one half an inch. On longer stretches of gutter, or when there are sudden changes in temperature, gutters can become permanently distorted or even tear completely. The Hover floating continuous hanger provides the solution to this problem. Owing to its design, hemmed-back gutters can be suspended without having to be punctured. With this system, they can freely change shape when temperatures rise or fall. Therefore, gutters maintain their integrity and flexibility, regardless of changes in temperature or the amount of water they drain. The Spring Back technology is based on the flexibility provided by the shape memory of aluminum to increase the load capacity of floating continuous hangers in winter. The Spring Back will prevent distortion under a weight in excess of 400 pounds per linear foot. By distributing the pressure along the entire length of a Hover continuous hanger, this will greatly extend the lifespan of gutters. Complete with a lifetime strength warranty, the Hover floating continuous hanger is the gutter solution designed to weather the North American climate. Alu-Rex. Once and for all, it's the right choice.
