Product Description

SUNTHERM Rock Wool Board:The production of rock wool board uses natural basalt ore as the main raw material, through high temperature melting, high-speed centrifugal spinning into fiber, with cash three-dimensional production technology, adding a small amount of binder, and finally heating solidification into high strength board. Cooperate with other external wall insulation materials to improve building insulation and fire performance.
