SeaHawk Mylar is a premium reflective polyester (PET) film bonded to a strong 110 µm black poly backing for enhanced durability and light-tight installation. Its high-gloss mirror finish reflects up to 98 % of light, helping growers maximise usable light while reducing energy consumption. The durable backing prevents tearing and keeps the film flat for easy installation. Ideal for lining grow rooms, tents, or propagation spaces to boost light bounce and maintain thermal insulation.
Available in 1.2 m width with roll lengths of 7.5 m or 30 m, SeaHawk Mylar is lightweight, flexible, and perfect for commercial and hobbyist setups looking to improve canopy light uniformity without hot spots.
