Solar radiation during the day raises the air temperature inside the greenhouse. The house loses heat during the night. Add thermal film specifically using IR can absorb infrared radiation and heat loss during the night decreases. Add IR Infrared reflection and action that makes a difference in temperature of about 4 degrees warmer than the additive is no coverage. Materials distributed IR light when the sun is intense helps prevent harm to crops and products on time and to grow together. The film is also known as thermal cover.
