Customization:
With basalt rock wool composition and waterproof board design, you can achieve long-lasting thermal and acoustic insulation even in humid environments*. This corrosion-resistant material outperforms traditional fiberglass or organic-based insulation prone to moisture damage.
With adjustable thickness options from 50mm to 200mm, you can tailor insulation to specific project requirements, offering greater flexibility than rigid, fixed-thickness alternatives*. The adaptable design ensures optimal performance for both thin wall cavities and thick roof assemblies.
With applications across residential villas, commercial offices, and industrial warehouses, you can deploy this insulation in diverse settings for uniform thermal and acoustic performance*. Its versatility meets the needs of schools, hospitals, and malls, unlike insulation limited to single-use environments.
With certifications including ASTM C518 (thermal resistance) and EN13501 (fire safety), you can ensure compliance with international standards for thermal efficiency and fire resistance*. This exceeds basic requirements, aligning with stringent regulations in Europe and North America.
With ASTM E84 fire resistance certification (Class A), you can guarantee low flame spread and smoke development, enhancing safety in high-traffic commercial buildings*. This surpasses non-certified insulation materials prone to rapid combustion.

⭐⭐⭐⭐⭐ James Whitaker - Commercial Construction Manager
"We specified Thermrock’s Advanced Model for a new office complex in Chicago, and it’s performed flawlessly. The 150mm thickness delivered excellent thermal retention during harsh winter months, and the EN13501 A2-s1,d0 fire rating was critical for passing municipal inspections. Installation was smooth with proper sealing, and we’ve seen measurable energy savings in preliminary utility reports."Purchase Date: October 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Dr. Elena Martinez - Facility Director, St. Mary’s Medical Center
"We needed reliable acoustic and thermal insulation for a sensitive hospital retrofit—noise reduction and fire safety were non-negotiable. Thermrock’s Pro Model with A1-s1,d0 fire classification and 0.9 sound absorption coefficient exceeded expectations. Patient wards are noticeably quieter, and engineering confirmed a 22% drop in HVAC load. The material is also EPR-compliant, which simplified our sustainability reporting in France."Purchase Date: February 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ David Lin - Homeowner, Pacific Northwest
"Used the Base Model 100mm boards to insulate my 1970s villa’s attic and exterior walls. I did the installation myself following the supplier’s guide—clean surfaces, vapor barrier at edges—and it held up perfectly through a wet spring. The difference in indoor comfort is real: fewer cold spots and much less road noise. Only reason I didn’t give 5 stars is that cutting the denser basalt wool required a sharper blade than expected."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Amina Patel - Senior Architect, Urban Spaces Group
"For a new shopping mall in Toronto, we needed dual-function insulation that could handle both temperature swings and crowd-generated noise. Thermrock’s 150mm Advanced Model reduced ambient sound by an estimated 40dB in common areas and maintained consistent indoor climate without overworking the HVAC. The fact that it’s ASTM E84 Class A certified gave our safety auditors immediate confidence. This is now our go-to for mixed-use developments."Purchase Date: August 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Tomas Becker - Plant Engineer, LogiCenters Inc.
"Installed 200mm Pro Model boards in a high-bay warehouse in Germany. Extreme temperature variations and chemical exposure from stored goods ruled out fiberglass. Thermrock’s chemical resistance (20+ substances) and R-value of 5.2 have kept the space stable year-round. No degradation after 6 months of operation, and the CE + EPR compliance made cross-border procurement seamless."Purchase Date: April 2025 | Usage Period: 2 months
