Abstract: A door leaf or casing frame for windows, doors or the like and a process preparing the same. The door leaf or casing frame is assembled by joining hollow sections (3-6; 7-10) and T-pieces with the use of a binder; the hollow sections are particularly of Duroplastic with longitudinally extending reinforcing fibers. A joint plate is disposed in the connecting joints or mitre joints (15, 15a) of the frame corners, said plate having through channels for the binder, T-pieces being integrated with the joint plate. In the production of the frame a glue or adhesive composition is sprayed through the channels of the joint plates into the gap in the area of the corresponding corner.

Abstract: A one-piece window frame profile having on its circumference a plurality of grooves, recesses or the like for receiving additional profile strips, seal strips and the like, and trims. The profile consists of Duroplast material reinforced by fiber strands and has a roughly L-shaped cross section, a closed hollow being provided in the long arm of the L-shape and closed hollow in the cross arm of the L-shape. The grooves provided on the circumference have undercuts. In a process for producing the profile, a plurality of fiber strands are continuously impregnated with a Duroplast hardening resin, preferably polyester, said strand are combined into one bundle which is axially inserted in an elongated run-through mold, whose inside is shaped accordingly to the shape of the profile shape to be produced. The fiber strands are so conducted that they surround shafts inserted into the mold to form the hollows of the profile. Resin is hardened in the run-through mold. Windows and doors are produced by using the profile.

Abstract: A closure panel assembly, such as windows, doors, a partition wall and the like, comprising a planar member secured in a profiled frame which is mounted for movement with respect to a complementary profiled fixed frame, such as a casing, against which it sealingly bears, in a closed position, to an aeration position being produced by exposing the profiled frame from the sealing position. There is provided in the aeration position an aeration gap between the profiled frame and the profiled fixed frame, on the side area of which there is disposed a flexibly sealing and/or noise-damping and/or fireproof material.
