Modern intelligent greenhouse usually chooses glass greenhouse. The greenhouse roof covers single-layer tempered glass, and sides cover twin-wall hollow glass panels.
Toughened glass is a type of glass heated to nearly the glass softening point temperature (600-650℃), with quickly cooling or chemically toughening treatment. It has good mechanical properties and thermal- shock performance, also known as tempered glass.
Hollow glass is made up of two or more pieces of glass edge sealed together, then there will be filled static and dry air between the glasses, and there is a certain vacuum performance. The main material is aluminum spacing strip, bending bolt, butyl rubber, poly sulfur, and desiccant.
