A system of a skirting board (1) and at least one fixing element (2) for connecting the skirting board (1) with a floor (P) and an adjacent wall (S). the fixing element (2) comprising a rigid part (3) to be fixed immovably to the wall (S) and a resilient assembly (4) engaging the skirting board (1), the skirting board (1) comprising an internal shelf (7) extending towards the fixing element (2). wherein the resilient assembly (4) comprises at least one resilient arm (6) extending parallel to the wall (S) and being adapted to resiliently deflect parallel to the wall (S), said at least one resilient arm (6) projects obliquely from the rigid part (3) towards the floor (P) and has a free ending (6), said shelf (7) comprising a coupling protrusion (8) adapted to be snapped with said fee ending (6) so that said coupling protrusion (8) is pressed by the at least one resilient arm (6) in a direction different from horizontal. in particular in a direction selected from a group comprising the vertical direction and a direction slanting both to the wall (S) and the floor (P).

A crown molding assembly that enables safely incorporating electrical and communications cabling within the crown molding by providing segregated compartments for electrical and copper communications cabling, wherein the decorative face is formed of a composite of fiber reinforcing polymer (FRP) including a fiber-reinforced structure having an increased directionality of said reinforcing fibers causing the decorative face to fracture upon being pierced by a fastener in a manner that renders the damaged section of the decorative face unable to hold the fastener, protecting the electrical cables and any other equipment located behind the decorative face from damage, and enables the secure installation of hardware either concealed within the molding or securely and favorably positioned through the decorative face to view or sense a room, and enables additional cable capacity that is concealed within a light reflector to increase lighting efficacy and power and data delivery capacity.
