<p>A building panel (10) is formed using particulate material (16), such as sand, with an adhesive binder, to form an aggregate. The mix undergoes a heating process to cure the adhesive, which also produces a porosity in the panel. The relative quantities of the materials are such that the resulting panel (10) is porous after heating, with the interstices (18) between particles (16) being devoid of binder material. The resulting porosity provides for the limited passage of air and moisture, particularly water vapor, through the panels (10) so the panels (10) may 'breathe' to allow circulation through a structure (S) composed of the present panels (10), and also provides acoustic properties.</p> |
