ROCKWOOL Frontrock stone wool insulation for EIFS offers high-performance building envelope design. Non-combustible and Class A fire-rated, Frontrock doesn’t trigger NFPA 285 when installed, per manufacturer instructions. Stone wool is dimensionally stable across changes in temperature and humidity and provides a dense, rigid surface with high impact resistance. Mechanically attached, stone wool EIFS resists wind loads and achieves drainage efficiency using adhesive ribbons, similar to existing drainage systems on the market. Designed for ease of handling, cutting and installation by adapting to wall irregularities, ROCKWOOL Frontrock is well-suited for field and panelized applications.
