The Outsulation® Mineral Wool + Securock® ExoAir® 430 system features non-combustible ROCKWOOL® mineral wool insulation, meeting strict standards such as ASTM E136, CAN/ULC S114, and NFPA 285/268 for exceptional fire safety. At the core is Securock® ExoAir® 430 factory-applied air and water barrier sheathing — eliminating the need for jobsite-applied fluid barriers and ensuring consistent, high-quality weather protection. Integrated vertical adhesive channels not only secure the insulation, but also create built-in, passive drainage paths that efficiently manage moisture behind the cladding. This combination provides a durable, code-compliant, and easy-to-install exterior solution that streamlines construction and delivers lasting building envelope performance.
Pre-applied at the factory for consistent performance, eliminates field-applied steps, speeds installation, improves jobsite quality control.
ROCKWOOL® Frontrock™ meets all major fire code requirements—ideal for demanding projects and high-rises.
Continuous insulation (R-4.0/inch) paired with an effective air barrier reduces thermal bridging, cuts energy use.
Vertical adhesive channels and integrated barrier efficiently drain incidental water, helping prevent mold and damage.
