A composite reinforced mull post is disclosed for use in an entryway assembly. The mull post may engage a door on one side and a side light window on the other side. The mull post may comprise a one or two piece outer portion and one or more internal reinforcing members. The outer portion may comprise a plurality of interlocking pieces. A first internal reinforcing member may be formed of engineered material such as a wood laminate, and a second reinforcing member may comprise a channel that extends partially around the first reinforcing member. The reinforcing member may include orthogonal portions conterminously received within a correspondingly shaped central chamber formed by the housing formed by the joined interlocking pieces. The reinforcing member may include an upper wood portion and a lower durable portion, connected end to end by a glued finger joint.

Embodiments herein include compositions, extruded articles, and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include an extruded segment comprising a first composition. The first composition can include a polymer resin, an impact modifier and fibers. In some embodiments, the extruded segment can have a surface exhibiting an average depression depth of less than 0.0045 inches (0.1143 mm). Other embodiments are also included herein.

The process for the realization of reinforcing bars for door and window frames comprises: a step of providing a reinforcing bar (1) made of a metal material having a drillable face (2); and a step of drilling of the drillable face (2) to obtain a fixing hole (5) in the reinforcing bar (1) having a characteristic dimension (A) comprised between 2 mm and 5 mm, wherein the reinforcing bar (1) is insertable into a profiled element (4) made of plastic material and the fixing hole (5) is configured to be penetrated by the softened plastic material of the profiled element (4) to define a riveting portion (6) for fixing the profiled element (4) to the reinforcing bar (1).

Disclosed are a composite aluminum alloy profile and a preparation method therefor. The composite aluminum alloy profile includes an outer decorative profile, a polyurethane elastomer structural adhesive, and an inner frame profile. The inner frame profile is an integral component of alkali-free glass fibers and polyurethane resin formed by one-time extrusion, and a cross section thereof is “”-shaped; and the outer decorative profile is connected to the inner frame profile through the polyurethane elastomer structural adhesive. The preparation method includes: preparing glass fibers and polyurethane materials of components A and B into a glass fiber resin reinforced profile by a compound strip-threading and injection machine, adhering the inner frame profile to the outer decorative profile through the polyurethane elastomer structural adhesive, and rolling the same. The profile has the features of heat and sound insulation and is easy to produce.

Disclosed is a window or door frame assembly having a jamb extension coupling a window or door frame. The window or door frame has a longitudinal member having a surface defining a channel formed along the length of the longitudinal member. A jamb extension having a first face and a second face, a plurality of spaced apart grooves formed on the first face and extending along the length of the jamb extension, with the jamb extension configured to matingly engage the channel. A tooth coupled to the longitudinal member and configured to engage one of the plurality of grooves for coupling the jamb extension to the window or door frame. Also disclosed are kits and process for the window or door frame assembly.

An extrusion profile of, for example, a polymer material, such as PVC, for a door system and/or window system, may include at least one hollow chamber extending in the extrusion direction, which is delimited by profile walls; and an insulation core of foam arranged in the at least one hollow chamber. The foam may have a compression strength of at least 0.3 N/mm.sup.2.

A modular window assembly including a base frame, an interior frame cover, and an exterior frame cover. The base frame has a first complementary fastener located on an exterior face and a second complementary fastener located on an interior face. Each of the interior and exterior frame covers have a complementary fastener configured to releasably mate with the first and second complementary fasteners of the interior face and exterior face, respectively.

A resin frame includes frame members combined into a frame shape that includes a corner portion, and a joint portion joining a pair of the frame members which are adjacent to each other at the corner portion. The joint portion includes an entire-surface welded portion, in which end surfaces of the pair of the frame members are welded to each other over an entire surface in a thickness direction of a plate portion of the frame members, and a partial welded portion, in which the end surfaces of the pair of the frame members are welded to each other on one side of the entire surface in the thickness direction while another side of the entire surface in the thickness direction is not welded. The entire-surface welded portion and the partial welded portion are present at different portions on an outer periphery of the joint portion.
