Released in 2019 our newest gutter protection mesh is designed for roofs that experience an extremely high exposure to overhanging trees and heavy debris. This mesh is 40% heavier than any of our other aluminium mesh products which offers increased strength. This product offers greater protection from damage cause from falling branches and hail storms and maintains the proven aperture of 3mm x 4mm making it very effective for eliminating most leaves from your roof guttering system whilst allowing high volumes of water to pass through. Available in 6 colours the 3.5mm heavy aluminium mesh has a strand width of 1mm and thickness of 0.7mm.
