Abstract

This article outlines the results of light transmission and heat loss in polycarbonate and in glass, which are often used as greenhouse construction. The object of the study is various materials for covering greenhouses, which are glass and polycarbonate. The purpose of the work was to study materials for covering greenhouses based on the following topics: consideration of materials for greenhouses, properties of polymers and glass, characteristics, sustainability in the conditions of the city of Almaty. The relevance of this article is the study of measurements of light transmission and heat loss of materials for covering greenhouses. As an experiment, a par lighmeter device was used to measure the luminous flux.

The objectives of this article:

  1. Calculate the amount of heat loss in greenhouses made of polycarbonate and glass.
  2. Determine the light transmission ability of glass and polycarbonate in the conditions of the city of Almaty.
  3. Identify a more suitable material for greenhouses.

As a result of the study, it was concluded that a greenhouse made of glass is ahead of polycarbonate in light transmission. But she showed great warmth.

The sum of the advantages of different materials suggests that these materials can be used on a large scale in the long term. A comparison of polycarbonate and glass has shown that each type of greenhouse cladding material has its own unique advantages and limitations.
