Rockwool & Glass Fiber Insulation Products


Rockwool and Glass Fiber are essential insulation materials used in modern construction to enhance energy efficiency and indoor comfort. As types of mineral wool insulation, they excel in temperature regulation, sound absorption, and fire safety. Rockwool is produced from natural stone fibers, while glass fiber insulation is made from fine glass strands. Both materials are durable and versatile, making them suitable for a wide range of building applications.


Advantages of Rockwool and Glass Fiber Insulation


These insulation materials deliver outstanding thermal, acoustic, and fire-resistant performance. Their superior thermal insulation helps reduce heating and cooling costs, maintaining comfortable indoor environments throughout the year. Both Rockwool and glass fiber insulation offer excellent fire resistance, providing valuable protection in case of fire. In addition, they significantly reduce noise transmission between rooms and floors, which is important for both residential and commercial spaces.

Sustainability is a key benefit. Rockwool and Glass Fiber are recyclable, non-toxic, and contribute to eco-friendly building certifications. Their long lifespan and resistance to mold and moisture make them reliable, low-maintenance choices for diverse projects.

Applications of Rockwool and Glass Fiber Insulation


Rockwool and Glass Fiber insulation are used in residential, commercial, and industrial buildings. In wall insulation systems, they help maintain stable indoor temperatures and reduce energy loss. For roof insulation, these materials provide essential thermal and sound protection, improving overall building performance. Floor and ceiling systems benefit from enhanced acoustic comfort and reduced heat transfer between levels. These insulation solutions are also widely used in HVAC systems, ducts, and industrial piping due to their high resistance to heat and fire. When paired with ceramic and porcelain tile finishes, Rockwool and Glass Fiber insulation contribute to interiors that are durable, energy-efficient, and visually appealing.


How to Select the Right Rockwool or Glass Fiber Insulation?


Selection FactorConsideration
Thermal PerformanceChoose higher R-value products for colder climates or improved energy efficiency.
Fire ResistanceOpt for Rockwool in areas that require superior fire protection.
Sound AbsorptionGlass fiber insulation is ideal for acoustic control in interior spaces.
Installation MethodBatts and rolls suit standard framing; boards are best for external and industrial applications.
CompatibilityEnsure insulation is compatible with wall finishes, including ceramic and porcelain tiles.

Frequently Asked Questions — Rockwool & Glass Fiber Insulation



Q: What is the difference between rockwool and glass fiber insulation? 

A: Rockwool (stone wool) is made from natural basalt or diabase rocks melted at high temperatures, producing fibers with excellent fire resistance (melting point above 1000°C) and superior acoustic performance. Glass fiber is made from recycled glass melted and spun into fine fibers, offering lighter weight and lower cost. Rockwool is preferred for applications requiring high fire ratings or acoustic isolation; glass fiber is commonly used for general building insulation and HVAC ductwork.


Q: What are the fire resistance ratings of rockwool insulation? 

A: Rockwool insulation achieves Euroclass A1 fire rating (non-combustible) according to EN 13501-1, meaning it does not contribute to fire spread and will not produce toxic smoke. This makes rockwool the preferred choice for fire-rated wall assemblies, structural steel protection, and marine applications where life safety is critical.


Q: Can rockwool and glass fiber insulation be used for pipe and ductwork? 

A: Yes. Rockwool pipe sections are pre-formed for standard pipe diameters and provide both thermal insulation and fire protection. Glass fiber duct wrap is the most common solution for HVAC ductwork. For high-temperature pipes (above 250°C), rockwool with wire mesh facing is recommended. For cryogenic pipelines, glass fiber with vapor barrier facing is preferred.


Q: How do I choose between rockwool board and glass fiber panels for wall insulation? 

A: Consider three factors: (1) Fire rating requirement — rockwool achieves A1 non-combustible rating while glass fiber is typically B-s2,d0 or C; (2) Acoustic performance — rockwool offers significantly better sound absorption (aw up to 0.95); (3) Moisture exposure — rockwool is naturally hydrophobic and performs better in humid environments.


Q: Does Cera Thermal provide custom sizes and thicknesses for rockwool products? 

A: Yes. We offer custom thicknesses (25mm to 150mm+), densities (40–200 kg/m³ for rockwool boards), and sizes for project-specific requirements. We also supply rockwool with customized facings including aluminum foil, fiberglass tissue, and black glass veil. OEM and project volume orders are welcome.
