Contractors, designers and installers now have an innovative and expanded options when it comes to insulation for thermal and sound applications. With codes and climate zones varying throughout the United States, Rockwool™ now has a thermal batt option for every area from the north to the south and coast to coast.
Rockwool has extended its Comfortbatt™ line with products available in several new R-values—R13/R21/R38, designed to provide customers with more options. In addition, Rockwool has released AFB® for wood stud applications—an acoustical fire batt that is now available in new dimensions designed for wood stud cavities.
Comfortbatt® R13/R21/R38: Using Comfortbatt® within the building envelope can contribute to a robust thermal insulation solution that meets the variety of code requirements that exist across the United States. Comfortbatt® is a semi-rigid stone wool batt insulation for exterior wood and steel stud applications in both new construction and renovations. Rockwool now offers Comfortbatt® in R13/R15/R21/R23/R30/R38.
Comfortbatt® features a unique flexible edge designed to aid installation. Simply compress the flexible edge as the batt is inserted and release. The flexible edge is designed to spring back, expanding the batt against the stud cavity to give a complete fill. This flexibility ensures the expected R-value is achieved and maintained.
AFB® for wood stud applications is a lightweight, acoustical fire batt stone wool insulation specifically designed for wood stud interior wall and floor applications. Its superior sound absorbency and fire protection contribute to the overall comfort and safety of occupants. It provides increased insulation density that reduces sound transmission. Traditionally, AFB® was designed for steel stud applications only. Today, we are pleased to introduce several new sizes designed for wood stud applications.
Like all Rockwool stone wool products, Comfortbatt® and AFB® are non-combustible and resist temperatures up to 2,150ËšF. They provide excellent sound absorption due to their density and non-directional fiber structure and are uniquely durable against all forms of weather (vapor permeable, water repellent, high drying potential). Rockwool stone wool products, including Comfortbatt® and AFB®, are manufactured using sustainable materials, like basalt rock (an abundant natural resource) and recycled steel slag.
