Our products

Built for every climate

Alu-Rex Double Pro product

Dual protection. One solution.

A perfect combination of two perforated aluminum membranes: the lower layer with large oblong openings, and the upper layer with precisely offset micro-perforations to form a highly effective filter.

Alu-Rex Double Pro installation

Unmatched support

Vortex™ technology uses a dual-membrane design that creates powerful suction, allowing your gutters to drain up to three times more water, even during heavy storms.

Alu-Rex Gutter Clean Pro product

Built for every condition

Eclipse™ technology with offset holes acts as a perfect filter: rainwater flows freely while pine needles and leaves stay outside.

The most common problems.

Peeling paint and rotting wood

Exposed wood around windows, doors and rooflines needs constant repainting — and once moisture gets in, rot follows fast.

Clogged eavestroughs

Leaves and maple seeds fill unprotected gutters every fall — a small handful of debris is enough to make the whole system overflow.

Water near the foundation

Overflowing gutters send heavy rain and snowmelt straight to your foundation, where it causes cracks and basement leaks.

Lake Huron winters

Snow squalls, ice, and freeze-thaw cycles off the lake punish siding, fascia, and gutters that weren't installed to handle them.
