Dual-Layer Microfiltration

• Alu-Rex is the world pioneer in using two perforated aluminum membranes in a gutter guard. The second membrane blocks access to fine, tapered debris—like pine needles, which are often the cause of major clogs—while still allowing the viscous substances to flow through, which can be problematic when perforations are too small.
• This technology effectively prevents leaves and small debris, including pine needles, from entering the gutter.
• Backed by a lifetime clog-free warranty, even in coniferous areas—maintenance is only required if necessary.

 The DoublePro Makes Your Gutters Stronger

• Can support the weight of snow, ice, and ladders.
• Prevents snow from entering the gutter, eliminating the risk of deformation caused by expansion during freezing and thawing.
• Supports up to 425 lb (193 kg) per linear foot.
• Comes with a lifetime warranty on sturdiness.

Innovative Design

• With the DoublePro continuous hanger system, strength is uniform along the entire length of the gutter.
• There are no weak points. It can even hold the weight of three people at once.

• Snow and ice remain on top of the product
• Does not rust or warp
• Your gutters will drain normally when it rains or the  weather warms up.
• Protects against expansion caused by snow and ice thawing and freezing inside of the rain gutter.

• Snow and ice remain on top of the product

• Protects against expansion caused by snow and ice thawing and freezing inside of the rain gutter.

• The suction created by the two membranes increases the drainage capacity to three times  the volume of the heaviest storms. The lower membrane draws water through the larger perforations.
• Provides a drainage capacity of 40.6 in (1,031 mm) of water per hour per linear foot.

• The double membrane keeps debris from getting inside the gutter. The offset holes make it the perfect filter, allowing water to drain freely while blocking pine needles and leaves without ever getting clogged.

• Keeps water inside the evavetroug even during heavy rains. 
• No overflow, according to independant tests.
