A profile for window, door, facade or cladding elements is disclosed, which comprises a profile body (2) made from thermoplastic material and extending in a longitudinal direction (z) with an essentially constant cross-section (x-y) along the longitudinal direction (z) and having at least one outer surface (2a), and a metal containing layer (4) deposited on at least part of the at least one outer surface (2a), wherein the thermoplastic material is polyamide, propylene, wherein the metal containing layer is made of aluminium or aluminium nitride or chromium, wherein the metal containing layer (4) is deposited directly on the profile body (2) using a PVD technology, and wherein the metal containing layer has a thickness in the range from 110 nm to 170 nm.

A profile for a fenestration system includes a first portion and a second portion offset from the first portion and thereby defining an inner space therebetween. The profile for a fenestration system further includes a retention mechanism arranged within the inner space, and one or more communication lines mounted to the retention mechanism.

Disclosed is a fixed frame or opening frame, resulting from an assembly of joinery profiles, forming the mullions and the cross-members of the frame, with the profiles of the mullions and the cross-member profiles being assembled by their ends. The frame includes at least one device for compressing, including at least one mechanical connection extending interiorly along an intermediary portion of the frame, the at least one mechanical connection connecting by its ends of supports of the device for compressing, the supports being integral respectively with mullions or cross-members, on either side of the intermediate portion of the frame, the mechanical connection being solicited in traction in order to provide the maintaining under constraint of the ends of the joinery profiles of the intermediate portion of the frame against the corresponding ends of the joinery profiles, arranged on either side of the intermediate portion, belonging to the mullions or cross-members.

Devices, systems, and methods related to a fenestration unit are described herein. The fenestration unit may include a frame including a plurality of frame members, wherein the plurality of frame members includes an upper rail member, a lower rail member, a first stile member, a second stile member, the lower rail member including two parallel metallic extrusions a space defined therebetween and a thermal break coupled to the lower rail member and located within the space. The thermal break may include a solid body of thermally insulating material defining a first side portion, a second side portion, and an intermediate portion between the first side portion and the second side portion, the solid body of thermally insulating material being asymmetrical about an X-Y plane.

A frame assembly for a window, door or wall comprise trusses that serve as a structural support and a thermal break. The frame assembly includes an inner frame portion and an outer frame portion, with the trusses mounted there-between. The trusses comprise thermally insulating strut members that have a lower thermal conductivity than the inner and outer frame portions, and in some embodiments between can be composed of carbon fiber. The thermally insulating strut members enables the trusses to serve as thermal breaks and provide heat insulation between the inner frame portion and the outer frame portion, while providing structural support to the frame assembly.
