Cork
Sandell's Cork is manufactured from all natural components and is available standard or self expanding. Unlike many other products used for expansion and contraction, cork is one of the most durable products on the market today. Cork will not collapse over time like other fibrous materials, but on the contrary, retains its shape and structural bond perfectly. Cork is water resistant and always forms a precise seal so that gasses and other elements cannot penetrate the joint. Sandell's Cork is the proper choice for insulation, in that it is fire resistant, does not absorb dust and is non-toxic when burned. It can retain shock and sound like no other substance and its uses are infinite.
