The present invention consists in fabricating a door with two laminated covers placed facing each other and separated by a separator plate of light and insulating material; in this separator plate it will be integrated another one or a device for fastening the door lock. The frontal dimension of the door will be practically defined by the three mentioned elements placed as specified (sandwiched) and joined preferably with an appropriate glue forming a monolithic conjunct (laminated cover-separator plate) being a functional point of view; the door thickness practically will be defined by the separator plate for the thickness of the laminated sheets is very small. The latter conjunct itself will be unprotected by its corresponding perimetral ends to the door width; generally, in other systems the protection is offered by a perimetral framework or a wooden frame covered by the laminated covers, except in a tiny edge that juts out; in this wooden frame it can be done the so-called adjustm ent operations, consisting in brushing said edge so the door can be adjusted conveniently in the bay or opening in which it is going to be placed. In the present invention the frame is made in general, with four perimetral sills laminated from a profile whose ends have two arms as the "U" profile, so that when joining them to the lateral edges of the laminated covers can be assembled to them, acting said arms as braces covering the perimetral part of the conjunct, laminated covers-separator plate. The latter apart from protecting said conjunct allows the adjustment operation (of cm fractions) varying in more or less degree the surface assembly if the door dimension is not previously known. With the assembly, the laminated covers-frame, it is possible to make the structural union by many of the systems mentioned in the description.
