ABSTRACT:
An insulated curtain slat for use in a roller curtain has inner and outer skins. The outer skin is typically made of a metal to protect against weather conditions, and the inner skin is generally made of a plastic material to minimize the transfer of heat between the inside and outside of the curtain. A space between the skins is foamed with an insulating material. The top and bottom of the outer skin are formed with hook-like ridges, so that neighboring slats may engage one another at a joint to form the roller curtain. A sealing edge is fastened to an edge of the inner skin of each slat. The sealing edge spans the joint between the neighboring slats and contacts the inner skin of the adjacent slat, thereby sealing the joint. The sealing edge is made of a rubber or elastic plastic material which, along with an air pocket created by the sealing edge, further reduces the transfer of heat between the inside and the outside of the roller curtain.
