Is this board safe near a fireplace or stove?

Mineral wool is non-combustible and made for high-heat areas, so it suits fireplace surrounds and flue clearances. Keep it behind a non-combustible facing and follow the stove maker's clearance distances.

How many boards do I need for a fireplace surround?

Each board is about one square foot, so measure the area and add roughly 10 percent for cuts. A typical surround takes several boards.

Yes. Mineral fiber board cuts with a sharp utility knife or a fine-tooth saw. Wear gloves, eye protection and a dust mask.

Does it work for soundproofing?

Mineral wool absorbs sound well inside stud bays and behind panels. It reduces echo and mid-range noise but will not block sound on its own without mass and sealing.

It resists moisture and does not hold water like some batts, but it is not a waterproof barrier. Keep it dry and pair it with proper flashing or vapor control.
