A Unique Technology in The World of Gutter Guards

At first glance, the DuoPro is similar to the famous Leaf Relief Continuous Hanger offering the same strength and durability, but DuoPro has a second layer of perforated aluminum. After dozens of prototypes and hundreds of tests, this innovative and patented design is preferred: two layers of aluminum working hand in hand to increase filtration and reduce the maintenance of your gutters.

Few people know how effective the development of efficient rain gutters is: you have to filter as much as possible while letting the rain pass without the filter clogging! The perfect model would assume that the gutter guard is ultra-strong while removing maintenance. Every homeowner in Savannah affected by gutters clogged with pine needles or sprouts dreams of the day when he or she will definitely be able to put away the ladder, pail and gloves. Leaf Relief DuoPro brings us closer to this reality.

But does this second layer of aluminum reduce drainage capacity?

Short answer: NO!

In fact, this second layer of aluminum is so close to the first that a suction effect is created. Water on the surface of the leaf screen is sucked into the perforations of the first layer to drain through the second layer. If you are a scientist at heart, this is called the surface tension and at Leaf Relief it is the Vortex™ effect.

Vortex™ technology, exclusive to Leaf Relief raises the continuous hanging debris guard to the same drainage capacity as other Leaf Relief products, more than twice the amount of rain that has fallen during the largest storm ever recorded (Holt, Missouri, USA, 1947).
