What color asbestos was most commonly used in building products?

The most commonly used type of asbestos in building products is chrysotile, also known as white asbestos. Chrysotile accounted for the majority of asbestos used in construction materials, including insulation, roofing, and flooring. Other asbestos types, like amosite (brown asbestos) and crocidolite (blue asbestos), were used less frequently. However, due to health risks associated with asbestos exposure, its use has been heavily regulated or banned in many countries.
