String Reinforced 6 Mil White Overwintering Film is a strong and durable plastic film that can be used for greenhouses and will help plants survive the winter and make sure they continue to grow. Energy conservation: The film helps reduce heat loss from the greenhouse minimizing the need for additional heating during winter. By retaining heat more effectively it can significantly lower energy costs associated with greenhouse heating. This is particularly important in regions with colder climates where heating expenses can be substantial. Light Diffusion: This product is engineered engineered from an opaque plastic that works great as a light diffuser. Light diffusion will reduce direct sunlight rays and eliminate shadows keeping the temperature inside your greenhouse even. Light Transmission: This product has 55% light transmission which will keep a consistent temperature by reducing hot spots and cold spots. This percentage of light transmission will make sure that your plants get the correct amount of light during the winter. Plant health and growth: By shielding plants from extreme cold and frost the film helps maintain more stable temperatures inside the greenhouse. This stable environment promotes healthier plant growth and development as well as better crop yields. It also protects plants from wind damage reducing the risk of breakage or uprooting.
