A windproof greenhouse is a type of greenhouse specifically designed to withstand high winds and prevent structural damage or internal temperature fluctuations caused by wind exposure. These greenhouses typically feature stronger frames, durable materials, and wind-resistant designs

For a greenhouse to be considered windproof, it typically must withstand wind speeds of 60 to 100 mph. The exact wind resistance can vary depending on the materials and design of the greenhouse, but here are some general guidelines:

• 60-75mph: Standard for many high-quality residential greenhouses with reinforced frames and polycarbonate panels.

• 75-85 mph: Greenhouses designed for moderately windy regions, with additional anchoring systems and more durable materials.

• 100 mph or more: Commercial-grade or heavy-duty greenhouses with specialized engineering to withstand severe winds.
