<p>Proposed is a composed wooden profile, which is intended for manufacturing of window and door wings (2) and frames and which consists of at least three ledges (11, 12, 13), which are assembled and sealed along their complete length, namely of lateral ledges (11, 13) as well of at least one intermediate ledge (12) arranged there-between, wherein at least said intermediate ledge (12) comprises a longitudinal, generally continuous recess (120), which is filled with corresponding insulating filler (125). On both ends of the ledge (12), said recess (120) is ended at certain distance apart from each end portion (121, 122), in which each profile (1) is assembled with each adjacent profile (1) of each window or door wing (2) or frame (3) in each corner area (21, 31) thereof. The wing (2) or the frame (3) of each window or each door as formed by such profiles (1) excel in improved thermal-insulating properties by simultaneously maintaining excellent rigidity, in particular in the corner areas (21, 31). ?</p> |
