The invention concerns an arrangement for improving the thermal insulation of windows in which the outer face of the window frame (1) is provided with a casing (5) of weatherproof material which forms a cavity (17) and has the side of the casing not adjacent the masonry (8) turned inward toward the pane of glass (3) where it is fitted with a permanently elastic gasket (10) which makes contact with the glass. The cavity is filled completely with thermal insulation material. Using the arrangement according to the invention allows a thermal transmittance value for the complete window (Uw-value) of less than 1 to be achieved. |
