1. Structural Wall Assembly
2. Owens Corning Thermafiber® Mineral Wool

• A high-density mineral wool core providing continuous exterior thermal control that resists fire and withstands temperatures in excess of 2000º F.

1. Sto Thermo Dowel

• Pre-assembled fasteners specifically designed to minimize thermal conductivity, with options for surface mount or countersunk applications depending on insulation board thickness and type of framing. Countersunk dowels are used with a Sto Thermo Countersunk Tool to compress the insulation board and achieve proper depth, and are covered with Sto Thermo Cap Wool to further minimize thermal conductivity.

Barrier and Protection Components

1. StoGuard® Air & Moisture Barrier

• Seamless air and moisture barrier ensuring compatibility and continuity of the air, vapor, and water control layers.

2. Sto 10mm Drainscreen®

• Promotes drainage and drying, enhancing moisture management and overall wall system performance.

Finishing Components

1. Sto® Mesh
2. Sto BTS® Plus
3. StoPrime®
4. Sto Textured Finish

• Provides virtually unlimited finish color selection and multiple textures, offering extensive design freedom.

Superior Fire and Acoustic Control

1. Fire Resistance
