DETAILED DESCRIPTION OF THE INVENTION

[0018] Before explaining the disclosed embodiment of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the particular arrangements shown, since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

[0019] As shown in FIGS. 1 and 2, a panel 1 is made of glass fibre reinforced concrete (GRC). The panel 1 has a front face 2, a rear face 3, an upper edge 6 and a lower edge 7 and side edges 9. The following GRC panel 1 comprises a main wall with side edges 9, from which extends two side walls 11. All three walls are integral. Moreover, the GRC contains an inorganic colouring pigment to provide distinctive colour of the GRC panel and in that a thickness of the GRC panel is 25 mm, and in that the front face 2 of the GRC panel 1 is profiled so to resemble a bricked wall with a brick surfaces 4 and grooves 5 therebetween. The grooves 5 are filled with a mortar 10. Moreover, the mortar 10 is in grey colour but the GRC panel 1 is in red colour, wherein the red colour resembles a red colour of bricks. The GRC panel 1 further comprises a frame structure 12 attached to the rear face 3 of the GRC panel 1.

[0020] As shown in FIG. 3, a GRC panel 1 comprises one side wall 11 extending from the one of the side edges 9 of the GRC panel 1 substantially orthogonal to the front face 2 of the GRC panel 1, wherein the side wall 11 runs along the entire length of the side edge 9 of the GRC panel 1.

[0021] As shown in FIG. 3, is a close up view of a cross-section of the GRC panel 1 taken along lines A-A from FIG. 3a. GRC panel 1 comprises a front face 2 that has formed brick surfaces 4 and grooves 5 resembling brick wall. The grooves are filed with mortar 10.

[0022] As shown in FIG. 5, is a technological process of manufacturing a panel 1 resembling a brick wall. A method or process of manufacturing aforementioned a panel 1 includes the following steps. The GRC is prepared or provided containing glass fibres. An inorganic colouring pigment is added to the GRC to obtain necessary colour of the GRC. After preparation of the GRC in necessary amount and colour, the GRC is poured into the panel mould having profiled surface that resembles brick wall having brick surface and grooves. When the GRC is filed in the panel mould in necessary amount, the GRC is left for curing. During curing, the frame structure 12 is attached to the rear face 3 of the cured panel, in result of which the frame structure 12 is integrally connected to the rear surface 3 of the panel 1. After curing, the panels 1 is removed from the panel mould. After removal, the grooves 5 are filed with the mortar so that the panel 1 resembles a brick wall.

[0023] The invention has been described with reference to various specific and illustrative embodiments and techniques. However, one skilled in the art will recognize that many variations and modifications may be made while remaining within the scope of the invention as defined in the appended claims.
