ROCK WOOL SANDWICH PANEL

DUOWEI new model fireproof rockwool sandwich panel is recombined into a beautiful, flat, and tough building board by choosing two layers of high-quality color coated steel sheets or other precisely profiled metal sheets as its faceplates, rotating the stripped rockwool 90 degrees after roll forming (make the fibers vertical to the upper and lower steel sheets) and strongly binding high-quality rockwool with the metal faceplates using high-strength, high-adhesion, high-fire-prevention binder. Excellent fire-prevention, thermal insulation, environment protection and other characteristics of the formed boards provide a best choice for industrial building envelope system.

Core Material Index of DUOWEI New Model Fireproof Rock Wool Sandwich Panel

Note: usually, the material with low heat conductivity coefficient is regarded as thermal insulation material (it is stipulated that all the materials with
a heat conductivity coefficient no more than 0.12w/(m•K) when the temperature is lower than 350℃ called thermal insulation materials in national
standard.), and the material with a heat conductivity coefficient less than 0.05w/(m•K) is named high-efficient thermal insulation material.
