The SEF Poly Greenhouse series brings high-performance engineering to a versatile, cost-effective platform designed for diverse climates and specialized crop cycles. These structures utilize advanced polyethylene films that provide superior light diffusion, reducing hot spots and ensuring a uniform canopy growth. Our poly solutions are engineered with the same structural integrity as our high-tech glass facilities, featuring a high-strength Gothic-arch design that maximizes internal air volume and improves natural ventilation, creating a resilient microclimate optimized for everything from high-density leafy greens to robust nursery stock.

What distinguishes an SEF Poly structure is our vertically integrated manufacturing. While many poly houses are sold as basic kits, SEF designs and fabricates the sub structure in-house at our Leamington facilities to withstand heavy North American snow and wind loads. Our design-build approach seamlessly integrates all components and eliminates the compatibility issues often found in multi-vendor projects, providing a single partner solution that accelerates construction timelines and ensures your facility is operational with a quicker planting date.
