DoublePro®: dual membrane, zero clogs
The dual membrane keeps debris from ever reaching the inside of the gutter. Its offset perforations promote drainage while blocking needles and leaves.
Eclipse™ technology
The offset holes act as a perfect filter: rainwater flows freely while pine needles and leaves stay outside.
Vortex™ technology
The suction effect created by the two membranes brings drainage capacity to three times the volume of the heaviest downpours.
The challenges our homes face
Leaves and debris
Every fall, leaves and twigs clog the gutters. Our gutter guards eliminate the cleaning chore for good.
Snow, ice and freezing rain
Freeze-thaw cycles and ice dams typical of Terrebonne and Montreal North Shore region: guards and installation must let meltwater drain.
Conifer needles
Pines and spruces around Terrebonne shed needles that clog standard gutters. Alu-Rex offset perforations keep them outside.
Heavy rainfall
An undersized drainage system overflows and threatens the foundation. We size the system for your downpours.
