Delivering high-performance, hybrid insulation solutions since 1997, InsulVail partners with homeowners and builders across Summit, Eagle, Garfield, and Pitkin Counties to install Rockwool Blow & Batt systems that maximize thermal efficiency, sound control, and fire safety.
Combining the best of loose-fill and batt insulation, Rockwool Blow & Batt delivers:
This hybrid approach fills voids and irregular cavities with blown mineral wool, then adds a batt layer to lock in R-value and minimize air leakage.
A Blow & Batt installation uses two layers of Rockwool:
1. Blown-In Mineral Wool: Pneumatically installed to completely fill wall cavities, rim joists, and attic floors.
2. Comfortbatt® or Safe’n’Sound® Batts: Installed over the blown layer, these dense batts ensure consistent thickness and compressive stability.
The result is a continuous insulation envelope that outperforms standard batts or loose-fill alone.
1. Site Evaluation & Preparation: Assess cavity depths, existing insulation, and air-sealing needs. Mask off openings and protect surfaces.
2. Blown-In Application: Fill cavities with loose-fill Rockwool to fully envelope wiring, plumbing, and irregular framing.
3. Batt Installation: Install Rockwool batts over the blown layer, ensuring tight fits around outlets, headers, and penetrations.
4. Air-Seal Detailing: Seal gaps at band joists, top plates, and around windows/doors with foam or caulk.
5. Quality Verification: Inspect coverage, measure cavity densities, and perform optional blower-door testing to confirm airtightness.
Blow & Batt offers similar air-seal and R-value benefits without chemical off-gassing. It’s also more cost-effective and easier to retrofit.
Yes. Rockwool is non-combustible, does not off-gas, and its inorganic fibers resist mold, mildew, and pests.
Depending on cavity depth, you can achieve R-20 to R-38 in stud walls and up to R-60 in attic applications with a properly designed Blow & Batt system.
Absolutely. The dense batt layer dampens airborne noise, making it ideal for home theaters, bedrooms, and shared walls in multifamily units.
