Rock Wool Products for Different Project Requirements
Choose the rock wool product according to your application, installation method and required specification.
Rock Wool Mattresses & Blankets
Flexible insulation materials ideal for wrapping pipelines and irregular structures.
Rock Wool Boards
Rigid panels for effective thermal, fire, and acoustic insulation in building systems.
Rock Wool Pipes
Pre-formed sections for easy installation on industrial and energy pipelines.
Need Something Customized than a Standard Rock Wool Product?
Standard products don’t always fit the actual installation.
Forms & Colors
Choose from standard rockwool boards (slabs), batts, blankets, and pipe insulation (pipe lagging) sections, or request custom shapes like wall panels, acoustic panels, rigid insulation panels, and specific colors tailored to your designs.
Dimensions & Fiber Tech
We meet your exact length, width, and thickness specifications (e.g., rockwool 100mm, 50mm, 80mm, 40mm, 30mm), providing precise 100mm insulation rockwool solutions. Our capability extends to producing high-quality rock wool insulation material with ultra-fine fibers (≤3μm diameter) for enhanced performance.
Wide Density Range
Choose from a wide range of rock mineral wool densities. We support specialized low-density formulations for weight-sensitive applications or specific acoustic designs, optimizing the balance between performance and weight.
Thermal Performance
Tailor your rockwool thermal insulation / rock wool thermal insulation to meet demanding energy efficiency standards, capable of achieving thermal conductivity values below 0.032 W/(m·K) under specific conditions.
Performance Parameters
Define critical properties like fire rated rockwool non-combustibility (e.g., Euroclass A1 non combustible rockwool insulation, superior fire resistant rockwool performance), target R-values for thermal resistance, and enhanced bio-solubility (addressing concerns sometimes labeled rockwool dangerous by ensuring fibers don't persist).
Component
Select different binders or other components for your rockwool mineral fiber insulation based on specific requirements such as temperature resistance, environmental standards, or bonding needs.
