Examples of Porous Materials. First, let’s take a look at examples of porous materials. This includes wood, paper products, sponges, some rocks, and most fabric. In contrast, marble, glass, and some plastics are not porous and contain very few open pockets of air (or pores). Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam)..
