Toughened Glass Glazing

Toughened glass, also known as tempered glass, is a high-strength and durable glazing material that is ideal for greenhouses. It undergoes a special heat treatment process that enhances its resistance to impact, making it less likely to break or shatter. In the rare event of breakage, toughened glass crumbles into small, granular pieces, reducing the risk of injury. Gardeners and plant enthusiasts value toughened glass for its safety, longevity, and ability to provide a clear and well-lit environment for optimal plant growth.

Black Powder Coated Frame

Vitavia Powder Coated Green Frame

The Black powder coated frame and optional base look great and protect the aluminium from weathering. Powder coating is a process where powdered paint is applied using an electrostatic charge to transfer the powder to the aluminium.

The aluminium is then heated to 200 degrees centigrade in special ovens which melt the powder and fuse it to the surface of the aluminium. This gives a durable and smooth coating when solidified. The powder coated frame or base now has a nice deep colour that is UV resistant with a life expectancy of over 25 years!
