The invention relates to an insulating curtain consisting of an inflatable element (1) which in an inflated condition is intended to cover a surface area and in a deflated condition to be stored adjacent said area. The inflatable element comprises airtight portions (9,11) and means which are adapted for filling these portions, the inflatable element thereby being fed out from the store (3). The airtight portions comprise at least one central (9) and at least one peripheral (11) airtight portion and the central portion is substantially airtightly compressible between two compression members (2), along at least a portion of its width, whereby the compressed area will define an inflatable part and a substantially deflated part of the inflatable element. Air ducts (6,7) are disposed within the element and are not compressed by the compression means for enabling the air supply to the airtight portions. Feeding the inflatable element from the store (3) is done by supplying air to the central portion (9).

An insulating curtain assembly comprising: (a) a flexible curtain element including an airtight central inflatable chamber and at least one airtight peripheral inflatable chamber, said airtight peripheral inflatable chamber being arranged so that, on being inflated, it expands against sealing surfaces, thereby substantially preventing air circulation to a predetermined area to be insulated by said curtain element; (b) storage means for storage of said curtain element in a contracted state and from which said curtain element can be fed out to extend over the predetermined area; (c) compression means adapted to effect generally linear airtight compression of said curtain element to subdivide, in airtight fashion, said airtight central inflatable chamber into an inflatable section disposed on that side of said curtain element which is beyond said compression means relative to said storage means and a non-inflatable section disposed on the same side of said compression means as said storage means; and (d) air supply means for supplying air sequentially first to said inflatable section of said airtight central inflatable chamber to thus cause inflation thereof and to generate a force at said compression means effective to feed out said curtain element and then to said at least one airtight peripheral inflatable chamber when said inflatable section of said airtight central inflatable chamber has reached its fed out position.
