The object of the present invention comprises some sealing elements for elevating sliding windows and doors by means of a component which is part of the guide along which the wings move, in addition to some joints with a special configuration, which are placed on the actual wings of the slides along the entire perimeter where the component which is part of the guide prevents the interior part of the profile of the slide from being at ambient temperature, thus achieving breakage of the thermal bridge from the outside of the interior profile and where the joints enable closure between the window wing and the guide with at least a triple contact between points of the joint and points of the guide or the window wing.
