Interior Building Materials: The materials used for the interior of a building can greatly influence the indoor air quality or IAQ and many traditional materials now have environmentally friendly versions.

For example, the standard wood stud can be replaced with engineered wood and wood support beams can be replaced with laminated versions that can actually be stronger.

There are specialized panels for use in humid areas, such as bathrooms and kitchens, and there are non-toxic types of paint, glues, sealants, stains, and caulk that are safer to use than oil or petroleum-based versions.
