BROADWOOL rock wool is made of select fine basalt as major materials which is pulled into 4-7µ non-continuous fibers. We totally have 3 producing lines Rock wool insulation and our rock wool has been exported over 80 countries with superior quality and competitive price.
Aluminum foil is the most frequently-used facing on rock woo insulation and increase insulation effect greatly.
