Fast self-check: does this sound like your home?
- You’re prioritizing wildfire resilience upgrades
- You want a non-combustible insulation option
- Attic or wall assemblies need better fire performance
- You’re remodeling and want improved sound control too
- You want insulation that holds shape over time
- You’re evaluating ember-resistant attic strategies
What we do
We keep the scope practical—built around comfort and measurable waste reduction.
- Recommend mineral wool where it provides real value (not where standard insulation performs just as well).
- Install in wall cavities and targeted attic areas with tight fit and clean edges.
- Address common attic leakage points to reduce ember and smoke pathways where practical.
- Coordinate with your overall attic strategy (insulation + sealing + ventilation).
- Explain tradeoffs: cost, density, and where other materials may be better.
Our process
- 1. Scope review based on goals (fire performance, sound, comfort).
- 2. Inspect assemblies and access (attic, walls, retrofit opportunities).
- 3. Install mineral wool with attention to full cavity fill and consistent fit.
- 4. Combine with sealing details when included in scope.
- 5. Walkthrough and next-step recommendations for comprehensive resilience upgrades.
Pricing factors
Most insulation quotes differ because the scope and access differ. These are the main variables we price around:
- Material cost and thickness requirements.
- Retrofit complexity and access (open walls vs. closed cavities).
- Whether the project includes air sealing and attic detailing.
- Square footage and number of assemblies.
- Coordination with other trades during remodels.
Why homeowners choose this upgrade
- Non-combustible material option for certain assemblies.
- Excellent sound control in walls and between living spaces.
- Holds shape well and performs consistently when installed correctly.
- Works well in combination with air sealing for better overall comfort.

FAQs
Is mineral wool better for fire protection?
Mineral wool is non-combustible and can improve fire resistance in certain assemblies. It’s one part of a broader wildfire resilience plan.
Can mineral wool be used in attics?
Yes, in specific applications. We’ll recommend where it makes sense based on access and your attic strategy.
Does fire-resistant insulation stop embers?
Insulation alone doesn’t ‘stop’ embers. Sealing pathways and detailing vents/openings is key. We can improve the attic plane where practical.
Is mineral wool more expensive than fiberglass?
Usually, yes. The value is in performance characteristics like fire resistance and sound control.
Does it help with heat?
Yes—insulation reduces heat transfer, but air leaks and radiant gain also matter.
Can you combine mineral wool with spray foam?
Yes. Hybrid approaches can be useful: foam for air sealing in key spots plus mineral wool where appropriate.
Is this recommended for homes near the foothills?
Many homeowners choose it for added peace of mind, but we tailor recommendations to the home’s design and your goals.
Do you install fire-rated assemblies for remodels?
We install the insulation portion. Fire-rated assemblies often involve multiple components—drywall type, sealing, and design details handled by the remodel team.
