ROCKWOOL Comfortbatt® R22 for Wood Stud Walls

Product Overview:

ROCKWOOL Comfortbatt® is a premium, semi-rigid batt insulation engineered specifically for wood framing applications. Made from resilient stone wool, it is designed to deliver exceptional thermal performance, superior fire resistance, and effective sound absorption for residential and light commercial construction. Its unique flexible edge ensures a snug, complete fill within standard wood stud cavities, guaranteeing the rated R-value is achieved and maintained over the life of the building.

Key Specifications:

• Material: Semi-Rigid Stone (Mineral) Wool

• R-Value: R22

• Thickness: 5.5 inches (140mm)

• Dimensions per Batt: 15.25" (W) x 47" (L)

• Coverage per Bag: 8 batts per bag, covering approximately 39.8 square feet

• Primary Application: 2x6 Wood Stud Walls (16" or 24" on-center)

• Fire Rating: Non-Combustible (ASTM E84)

• Certifications: GREENGUARD Gold Certified

Core Features & Benefits:

1. Precision Fit & Guaranteed Performance: The exclusive flexible edge compresses during installation and then springs back to expand tightly against the wood studs, creating a complete thermal and acoustic barrier without gaps, voids, or compression that can reduce effectiveness.

2. Unmatched Fire Safety: As a stone wool product, it is inherently non-combustible, with a melting point above 1,000°C. It will not contribute to flame spread or emit significant toxic smoke, providing crucial passive fire protection and enhancing building safety.

3. Superior Moisture Management: The hydrophobic (water-repellent) fibers resist moisture absorption, allowing incidental moisture to evaporate without compromising the insulation's R-value or promoting mold and mildew growth.

4. Exceptional Sound Control: The dense, fibrous structure effectively dampens sound transmission, significantly reducing noise transfer through walls and floors for a quieter, more comfortable indoor environment.

5. Sustainable & Healthier Indoor Air: GREENGUARD Gold Certified for low chemical emissions, contributing to healthier indoor air quality. Made from abundant volcanic rock and contains recycled material.

Ideal Applications:

• Exterior walls in residential homes and light commercial wood-frame construction.

• Interior partition walls where sound control is a priority.

• Renovation projects requiring high-performance wall insulation.
