BBT-SIP manufactured in Nordic or very Southern hemispheres with cold and dry climatic conditions can use wooden skins or facings such as OSB or Plywood, which are the mostly used. For tropical areas with high humidity and potential concerns of termites and other bugs, the appropriate facings are MGO or Magnesium Oxide boards. Sheeting such as Light Weight Cement boards might be another option.
SIP Panels are mostly used for Floors, Walls, Ceilings or Roofing.
