How To Use

How to Use Rockwool Stone Wool Insulation
1/ Unpack Carefully  Remove the insulation batts from the package and let them expand naturally.
2/ Measure & Cut  Use a serrated knife to cut the batts to fit around pipes, doors, or electrical outlets.
3/ Place & Fit  Insert the insulation snugly into walls, ceilings, or floor cavities. The friction fit holds it firmly in place without sagging.
4/ Finish & Seal  Seal gaps if necessary and cover with drywall or desired finishing material. You're done!

Description

ROCKWOOL AFB® – Fire & Sound Performance in One Board

ROCKWOOL AFB® (Acoustic Fire Batt) is a high-performance stone wool insulation board designed for interior partition walls in commercial and residential buildings.

It provides superior fire resistance, sound absorption, and durability, making it the professional choice for offices, multifamily buildings, healthcare facilities, schools, and high-performance residential projects.

Made from natural volcanic stone, AFB is noncombustible, water repellent, mold resistant, and dimensionally stable — meaning it will not slump, shrink, or deteriorate over time.

Ideal for:
• Interior steel or wood stud walls
• Demising walls
• Corridor walls
• Mechanical rooms
• Commercial partitions

Feature

1. Fire-Resistant  Non-combustible and delays the spread of fire for enhanced home safety.
2. Water & Moisture Resistant  Repels water, preventing mold, mildew, and bacterial growth.
3. Excellent Sound Absorption  High-density material reduces noise between rooms for a quieter living space.
4. Eco-Friendly Composition  Made from natural stone and up to 93% recycled materials.
5. Easy to Install  Cuts easily with a serrated knife and fits snugly without sagging.
6. Long-Lasting Performance  Chemically inert and durable, it won’t rot or degrade over time.
