Introduction
SHG Accordion Roof Vent Insect Netting is specially designed for greenhouse top ventilation windows. It adopts an expandable folding structure. The mesh stretches and retracts together with roof vents. As a result, it keeps blocking pests no matter how widely the vent opens.
This net prevents insects from entering while maintaining natural airflow inside greenhouses. Furthermore, we produce it from virgin UV-stabilized HDPE material. It fits Venlo glass greenhouses, sawtooth greenhouses and multi-span greenhouses. Meanwhile, customized mesh sizes and dimensions are available for global farm projects.
Core Features
Accordion Folding Suspended Structure
The suspended design matches the running track of roof vents. When vents close, the net folds neatly. When vents open, the mesh fully unfolds. Therefore, it avoids shaking, sagging and tearing under wind. It also saves indoor space of the greenhouse.
UV-resistant HDPE Raw Material
We use new HDPE added with anti-UV and anti-oxidation additives. It can resist outdoor high temperature and rain erosion. Its normal service life reaches 3–5 years.
Optional Mesh Sizes for Pest Control
We supply 40-mesh, 50-mesh and 60-mesh options. These specifications can stop thrips, whiteflies, aphids and leafminers. Specifically, each mesh balances pest isolation, ventilation and light transmission for flowers, vegetables and seedlings.
Good Air Permeability & Light Transmittance
The woven structure brings little barrier to air exchange. It will not weaken the cooling effect of roof ventilation. At the same time, enough light supports healthy crop growth and reduces internal humidity.
Reinforced Edge & Easy Installation
All edges are thickened and tightly stitched. Rope pockets are reserved for quick installation. The reinforced edges withstand repeated folding friction. In addition, the net is convenient for maintenance and replacement.
