Greenhouse with double glazed roof - has horizontal partitions between glazing, forming chambers communicating with atmosphere inside

摘要

The enclosure such as greenhouse is directly exposed to climatic conditions when in use. It has one or more walls of which at least a part transmits light. Two light transmitting sheets are spaced at a distance from one another. Horizontal fixed barriers between the sheets form with the sheets, a number of intermediate spaces. Most of these are in communication with the ambient atmosphere within the enclosure.
