Advantages of Rockwool
1. Made from stone (basalt rock) and recycled steel slag.These readily available and sustainable materials make Rockwool more durable, less irritating, and less dusty than fiberglass batt.
2. Higher R-values than fiberglass insulation.
For the same thickness, Rockwool provides a higher R-value, or for a given target R-value, you can use a less thick Rockwool batt choice, making installation more convenient (e.g. Rockwool 3.5" thick = R15 and 5.5" thick = R23 vs. Fiberglass: 3.5" thick = R11 and 5.5" thick = R19.)
3. Moisture resistant.
Rockwool actually repels water, and won't absorb moisture like its competitors. This keeps your insulation spaces dryer, and prevents degradation of the adjoining construction material.
4. Completely resistant to rot, mildew, mold, and bacterial growth.
Over the long term, Rockwool keeps performing without compromising the health and integrity of your home or commercial building.
5. Fire resistant.
Rockwool gives you peace of mind with a fire resistant design that makes safety a high priority in your living space.
6. Does not itch.
Anyone who has worked with fiberglass knows the continuing pain of this itchy material. Rockwool solves that problem upfront.
7. All-friction fit.
Make your installation easier and faster. Simply cut Rockwool slightly larger than the space, then easily wedge in for a tight, convenient fit.
8. Easy to cut precisely with a serrated blade.
A bread-knife blade is all you need (Rockwool has them available) to quickly and precisely cut pieces to fit, as well as cut out spaces for electrical boxes and other wall features.
9. Denser than traditional fiberglass insulation.
Rockwool effectively reduces airflow and essentially, sound transmissions. Its higher air flow resistivity means better sound attenuation for a quieter environment.
