Mineral Wool Insulation

Why homeowners ask for mineral wool by name

Mineral wool — often called by the brand name Rockwool — is spun from natural stone and recycled slag into a dense, heavyweight insulation. That density is what gives it qualities ordinary fiberglass simply can’t match.

It deadens sound, shrugs off fire, and repels water. For media rooms, bedrooms, bathrooms, shared walls, and mechanical rooms, it’s the premium choice — and soundproofing is far and away the #1 reason people ask for it.

Because mineral wool comes in dense batts, we install it in open walls and ceilings — so it’s ideal for new construction or a remodel when the framing is still exposed. (It can’t be blown into already-finished, closed-up walls.)

What's included

How we handle it

Serious Soundproofing

Its dense fibers absorb sound instead of letting it pass through. Mineral wool in walls and floors makes bedrooms, offices, and media rooms dramatically quieter — the #1 reason people request it.

Real Fire Protection

Mineral wool is non-combustible and withstands temperatures over 1,000°C without melting or releasing smoke, helping slow the spread of fire and adding precious time and peace of mind.

Water & Moisture Resistance

It’s hydrophobic — it repels water rather than soaking it up. That means it won’t rot, and it resists the mold and mildew that can plague damp areas like bathrooms and basements.

Where it shines

Best rooms for mineral wool

Because it does more than save energy, mineral wool earns its place in the rooms where sound, fire, and moisture matter most:

  • Bedrooms & nurseries — block hallway and street noise for better sleep
  • Media & game rooms — keep the sound in and the rest of the house quiet
  • Home offices — privacy for calls and focus
  • Bathrooms & laundry — moisture resistance plus sound control
  • Shared & party walls — separate bedrooms from living spaces
  • Mechanical rooms & around furnaces — added fire safety

Common questions

Mineral Wool Insulation, answered

Is mineral wool the same as Rockwool?+
Rockwool is the most well-known brand of mineral wool, so people often use the names interchangeably. We install premium mineral wool products for soundproofing, fire, and moisture resistance.
How much better is it for soundproofing?+
Significantly. Its density absorbs airborne sound far better than standard fiberglass, which is why it’s the go-to choice for bedrooms, offices, and media rooms.
Is mineral wool really fireproof?+
Mineral wool is non-combustible and withstands very high temperatures without melting or producing smoke, which helps slow the spread of fire. It’s a genuine safety upgrade.
Can you add mineral wool to my existing finished walls?+
Mineral wool comes in dense batts, so it’s installed in open walls and ceilings — ideal for new construction or during a remodel when the framing is exposed. We can’t blow it into walls that are already finished and closed up. If your walls are open, it’s the best soundproofing you can put in them.
Does it cost more than fiberglass?+
Yes, mineral wool typically costs more because it’s a denser, premium material — but for soundproofing, fire safety, and damp areas, most homeowners find it well worth it. We’ll give you an exact price at your free estimate.
