Arrangement for outer doors and the like which separate cold and hot spaces from each other, x comprising a per se known frame construction consisting of two spaced-apart profiles (1, 2) of metal or B other material having high thermal conductivity and members (3) inserted in grooves in the profiles to interlock the profiles, said members consisting of a material the thermal conductivity of which is inferior to that of the metal material, thin sheets (4 and 10) inserted in pocket-like recesses (5) in the profiles, and defining the inside and outside of the door, and foamed-in-place material (6) filling out the hollow space between said sheets. The novelty resides in that one of said sheets has been made non-influenceable by temperature variations and consists of a fabric (10) of woven glass or like material fastened up in the frame. |
