Bayliss have been manufacturing autovents since 1964. Based in Ashbourne in the UK, Bayliss are a family business with a high reputation for the quality and reliability of their products. The basis of all their automatic vent openers is the same. Within each autovent is a strong metal cylinder that contains a mineral wax that expands with the heat. This cylinder pushes a piston, opening your greenhouse window. So as the temperature rises the window automatically opens, as the temperature falls, the window closes. Made from stainless steel, brass and aluminium, the Bayliss autovents are designed to provide you with many years or service.
