Revamp Your Home with Blown-In Roxul Insulation: Say Goodbye to Old Insulation!
Introduction
Are you tired of drafts, high energy bills and outdated insulation that no longer performs? Blown-in Roxul insulation offers a modern, eco-friendly solution that transforms your home into a comfortable, energy-efficient sanctuary. Made from natural stone and recycled slag, this high-performance mineral wool fills every nook and cranny, delivering superior thermal resistance, soundproofing and fire safety. In this guide, we’ll explore why blown-in Roxul insulation outshines old insulation, how to install it over existing materials and the long-term savings you can expect.
Benefits of Blown-In Roxul Insulation Over Old Insulation
H2: Why Blown-In Roxul Insulation Is the Smart Upgrade
• Complete Coverage: Traditional batts can leave gaps around pipes, wiring and irregular spaces. Loose-fill Roxul fibers conform to every contour, sealing air leaks and preventing heat loss.
• Exceptional R-Value: With an R-value of 3.5–4.0 per inch, blown-in Roxul insulation outperforms many older materials. The result is a warmer home in winter, cooler air in summer and fewer heating or cooling cycles.
• Fire Resistance: Rated non-combustible up to 2,150°F, Roxul helps contain flames and slows fire spread, adding a vital layer of protection for families and property.
• Mold and Mildew Resistance: Unlike organic or fiberglass attic fills, mineral wool won’t absorb moisture or support microbial growth. It stays dry, maintains performance and preserves indoor air quality.
• Soundproofing: The dense, fibrous structure dampens airborne and impact noise, turning noisy living spaces into tranquil retreats.
• Eco-Friendly Composition: Made from abundant volcanic rock and recycled industrial slag, Roxul reduces landfill waste, uses fewer petrochemicals and carries certifications for sustainability.
How to Properly Install Blown-In Roxul Insulation Over Existing Insulation
H2: Step-by-Step Installation of Blown-In Roxul Insulation
1. Assess and Prepare
– Inspect current insulation for moisture damage, mold or pest issues. Remove any compromised material to ensure a dry, clean substrate.
– Seal air leaks around attic hatches, plumbing vents, electrical boxes and gaps in framing with caulk or expanding foam.
2. Protect Yourself and Your Home
– Wear gloves, goggles, a dust mask and cover exposed skin. Mineral wool fibers are non-toxic but can irritate if inhaled or touched.
– Lay down tarps to protect floors and ceilings from stray fibers.
3. Fluff and Load the Insulation
– Follow manufacturer instructions to “fluff” the Roxul bags. Proper agitation ensures the fibers will flow freely through the blowing machine.
4. Blow the Insulation
– Position the blower hose in the deepest cavity first, then slowly withdraw while filling. Aim for a uniform depth (check recommended coverage for your climate).
– Pay special attention to rim joists, kneewalls and wall cavities—these areas often harbor hidden heat loss.
5. Verify Coverage
– Use depth markers or yardsticks to confirm consistent insulation levels. Inspect visually to ensure voids are filled and joist bays are flush.
6. Finish and Clean Up
– Seal attic access points and replace any loose boards. Remove tarps and vacuum residual fibers. Proper disposal of empty bags and cleanup keeps your home tidy.
The Cost-Effectiveness of Using Blown-In Roxul Insulation to Improve Insulation Efficiency
H2: Calculating Your Long-Term Savings with Blown-In Roxul Insulation
• Lower Energy Bills: By reducing thermal bridging and air infiltration, blown-in Roxul insulation can cut heating and cooling costs by 15–30%.
• Durable Performance: Mineral wool resists settling and degradation, maintaining its R-value for decades—no topping up or frequent replacements required.
• Reduced Maintenance: Mold- and pest-resistant Roxul avoids moisture-related repairs common with cellulose or fiberglass.
• Potential Incentives: Many utilities and government programs offer rebates or tax credits for upgrading to high-efficiency, eco-friendly insulation.
With a one-time investment and rapid payback, blown-in Roxul insulation delivers both immediate comfort and lasting financial returns.
Common Questions About Blown-In Roxul Insulation
H2: Q&A on Blown-In Roxul Insulation
Q: Is blown-in Roxul insulation safe for my family?
A: Yes. It’s inorganic, free of formaldehyde and VOCs, and won’t off-gas harmful chemicals. Proper installation minimizes airborne fibers.
Q: Can I add Roxul over existing fiberglass?
A: Absolutely. As long as the fiberglass is dry and undamaged, Roxul can be blown on top to boost R-value and seal gaps.
Q: How thick should the insulation layer be?
A: Recommended depths vary by climate—typically 12–18 inches in cold regions, 10–14 inches in moderate zones. Follow local building codes for exact requirements.
