A greenhouse (also called a glasshouse, or, if with additional heating, a hothouse) is a structure with walls and roof made chiefly of transparent material such as glass in which plants requiring regulated climatic conditions are grown. These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external ambient temperature, protecting its contents in cold weather.
Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables or flowers. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimise conditions for plant growth.

Greenhouses can be divided into glass greenhouses and plastic greenhouses.
In domestic greenhouses the glass used is typically 3mm (or 1/8") 'horticultural glass' grade, which is good quality glass that should not contain air bubbles (which can produce scorching on leaves by acting like lenses).
Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass.
