Outsunny 4x3x2m Polytunnel Replacement Greenhouse Cover White PE Mesh With Roll Up Windows And Door

Keep your tunnel-style greenhouse productive through every season with the Outsunny 4 x 3 x 2m Replacement PE Cover. Designed to fit a walk-in tunnel setup, this white cover lets you continue growing even if the original shell suffers wear or damage.

The cover is crafted from tear‑resistant PE mesh cloth, delivering reliable protection for your crops while allowing essential airflow and light diffusion. Its practical design helps your winter garden stay active, so you can nurture seedlings, start new crops, and extend your growing season without rebuilding your structure.

Why this replacement cover stands out

• Secure, weather‑smart fit: a full 15 cm overlap on all edges gives you room to bury the edges in soil or add weights, keeping the cover taut and in place even with breeze.
• Efficient airflow: eight roll‑up windows let you tailor ventilation, reducing stagnant air and helping regulate temperature and humidity inside the tunnel.
• Easy access: a large zipped door provides hassle-free entry and exit, essential when tending plants or moving trays in and out.
• All‑around protection: the PE mesh fabric shields crops from light rain, light wind, and direct sun, supporting healthier growth without overheating.
• Exact fit for your frame: sized for a 200 cm high, 400 cm long, and 300 cm wide tunnel (door 200 cm × 165 cm; window 37 cm × 37 cm), this cover is a precise replacement for compatible Outsunny tunnel greenhouses.
• Durable, practical design: built to extend the life of your existing structure, helping you avoid frequent replacements and keep your growing space ready year after year.

Ideal use scenarios

• Maintaining a continuous growing cycle during light rain or mild wind without sacrificing light transmission.
