The technique of floating installation for laminate flooring is becoming increasingly popular, largely due to the technique's obvious practicality. Nonetheless, to guarantee lasting success of the installation it is crucial not to neglect the expansion that is liable to occur in the various elements making up the floor covering. A definitive solution to the problem of expansion, and one that is also perfect from an aesthetic stand-point, is provided by Profilpas of Cadoneghe (Padova, Italy). Following years of research in conjunction with the leading producers of laminate flooring, this company has developed a range of aluminium profiles making up a system called "Unisystem Plus". The advantages of this system, and the installation of curved floors, are described.
