Glass greenhouses
Many proponents of glass greenhouses say their main advantage
is aesthetic: to some they simply look better. Many greenhouse vendors
sell both plastic and glass greenhouses. While each material has its
own advantages, glass does have some distinct ones over plastic.
While some plastic greenhouses can be flammable, glass will not catch
fire. This gives glass greenhouses an edge in terms of fire safety,
but you also consider glass greenhouses more breakable
Glass greenhouses can also be cleaner. They can be hermetically sealed
against moisture and dirt. In addition, unlike polycarbonate twin wall
plastic, glass will not turn yellow from the sun.
