[0009] As shown in Figs. 2 to 5, the door or window assembly 20 with one or more glass inserts 80 of the present invention is directly constituted by four modularized frame members including a top rail-frame 30, a left stile-frame 40, a bottom rail-frame 50 and a right stile-frame 60 for setting the glass inserts 80 without need of a pair of partly hollow door skins.

[0010] Accordingly, the structure of the door or window assembly 20 with one or more glass inserts 80 of the invention comprises the top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50, the right stile-frame 60, four pieces of glaze beads 70 and the glass insert 80 which are by way of scarfing joint to assemble together the door or window assembly 20 with glass inserts 80 of the invention.

[0011] The top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50 and the right stile-frame 60 all have a modularized structure produced by extrusion forming technique, respectively.

[0012] Besides, the surface f1 of the top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50 and the right stile-frame 60 can be made into a smooth surface with single color or dual color or into a surface of simulated wood grain.

[0013] The material of the top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50 and the right stile-frame 60 of the invention can be of thermoplastic foam material or thermoplastic material, or the thermoplastic foam material or the thermoplastic material mixed with wood powder, wood chips or glass fiber.

[0014] As shown in Fig. 6, one of the extrusion surfaces f1 of the top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50 and the right stile-frame 60 of the invention can be coated with a hard PVC (polyvinyl chloride) shell f2 to form a waterproof surface with the same color or different color with the frame material by way of co-extrusion coating method.

[0015] As shown in Fig. 5, for setting the glass inserts 80 and fixing the glass inserts 80 by the glaze beads 70, the top rail-frame 30, the left stile-frame 40, the bottom rail-frame 50 and the right stile-frame 60 all have the same cross-section structure provided with a first connecting slot S1, a second connecting slot S2 and a mortise slot S3 being further formed in the second connecting slot S2.

[0016] Wherein the first connecting slot S 1 is shaped for setting and aligning the glass inserts 80, and the second connecting slot S2 is for mounting and aligning the glaze bead 70 for fixing the glass inserts 80. Particularly, the glaze bead 70 can be further shaped to provide a soft tenon 71 which can be inserted into the mortise slot S3 in the second connecting slot S2 to enable the glaze bead 70 to be more firmly installed in the second connecting a slot S2.
