The difference of Alu-Rex DoublePro Leaf Guard

Blog Written by Let It Flow Exteriors in Edmonton

There are more than 200 different gutter guards on the North American market alone, and that’s not counting the hundreds of patents for rainwater management systems.

Inventors and manufacturers have gone to great lengths to turn out the best possible gutter guards at reasonable prices, but homeowners remain unimpressed. Understandably so, since their gutters keep on clogging-often, it’s the gutter guard itself that clogs up.

Enter Alu-Rex. Based on customer feedback, the company decided it was time to get to the heart of the problem. The result-the all-new DoublePro System-is a marvel of ingenuity for your eavestroughs in Edmonton and Parkland County.

What Fine Filtering Can and Can’t Do

How do you keep a rain gutter from clogging? Turns out it’s not that easy. You might think a mesh or screen would do it. It sounds plausible. Indeed, many gutter guards use membranes that resemble bug screens, with holes no bigger than one or two millimetres across. And as it turns out, mesh gutter guards have a solid record of preventing debris as small as pine needles and shingles grit from blocking up rain gutters.

But sooner or later sticky substances build up things like mud, pollen, roofing tar, and sap –and get stuck in the gaps in the mesh. They harden like glue, and neither wind, nor rain, nor vigorous and tiresome scrubbing can break them down. So at the end of the day, fine-filter leaf guards haven’t solved the clogged gutter guards problem.

Doubling Down To Block Fine Debris

Perforated aluminum is another solution with a decades-long track record. Single-Layer systems are popular for their durability and because they offer a reasonable compromise between blocking the debris and absorbing rainwater. And since their smooth surface makes buildup easier to remove, there’s less scrubbing and scraping to be done upon the tippy end of a ladder.

For Alu-Rex’s experts, it was a no-brainer. Forget fine filtration and base DoublePros design on the properties of perforated aluminum.

Doubling Down To Cut Our Clogged Gutter Guards

The Key to it all was the idea of using two protective layers instead of one. The bottom layer’s main purpose is to keep any debris that gets through the tip layer from getting inside and blocking the gutter. Its big, oblong openings are offset from the micro-openings above them. So if, say, a pine needle tries to slip through the door, there’s actually no door to slip through.

All filters need occasional cleaning, and DoublePro is no exception. But with DoublePro the lion’s share of the cleaning is done by wind and rain. With human interventions few and far in between. Alu-Rex has positioned the two perforated aluminum layers so as to optimize self-cleaning. With DoublePro, the smoothness of the aluminum, small openings in the top layer, larger perforation in the bottom layer, and the space between the layer between the two layers all work together to move sap, tar, pollen, and other sticky substances along until they flow right out of the gutter-Naturally.

Sturdiness Where It Counts

With a large investment like new gutters, you want to ensure that they stay protected. Traditional gutter hanging systems, such as spike and ferrule and clip-on systems, are often susceptible to damage caused by snow and ice. From sagging under the weight of Snow in our chilly Canadian winters to dents and holes caused by ice dams. This can result in costly repairs and replacements of your gutter system.

This is where Alu-Rex’s DoublePro comes into play. Its design not only protects against leaves and pine needles but ice and snow as well. Supporting 250 Lb per liner foot helps prevent your eavestrough system from sagging or even being ripped off due to the weight. This helps protect your investment better than traditional spike and ferrule or clip-on hangers ever could.
