Superior's vinyl greenhouse windows have welded corners for strength and durability. Our vinyl extrusions are engineered with multi-chambering, providing structural rigidity and resistance to heat transfer and excellent energy efficiency. Superior's vinyl extrusions are chemically engineered to retain their natural color and beauty even in the most severe climates. They are designed to guard against atmospheric pollutants, corrosion, rain and the harshness of sunlight or winter freeze without flaking, peeling rusting or swelling for enduring beauty.
