摘要

A thermal insulating curtain, especially for use in greenhouses, which comprises a plurality of superimposed uni-directionally arranged tubular members with a common slat-like partition between each two adjacent ones of said tubular members. Each of these tubular members along its two opposite sides has a folding crease to allow collapsing said tubular members to thereby permit collapsing the entire curtain in a manner of a blind or to roll the curtain up in the manner of a shade.
