This fabric is of the kind used for the manufacture of screens for greenhouses.
LS America Aluminized Environmental Screens for Greenhouses & Shadehouses ... are scientifically designed to perform more than one function. LS screens not only provide shading tailored to a crop, but create a controlled climate that results in temperature and humidity stability, fewer plant diseases, lower energy costs and a more efficient use of labor. LS screens are constructed of strong, lightweight materials that combine aluminum strips with clear polyester strips woven through a polyester or HDPE mesh. The aluminum strips reflect sunlight to provide a more controlled growing environment. The clear polyester strips admit light during the day, but combined with the aluminum strip, deflect heat into the growing area, especially at night.
