BeyondSpan Rockwool Sandwich Panels combine high-density mineral wool insulation with durable pre-painted metal facings to deliver fire safety, thermal performance, acoustic control and fast installation for industrial and commercial buildings.
High-Performance Fire-Resistant Wall Panel
The rock wool core is installed with staggered joints and can be sealed with high-pressure PU/PIR edge foam. This hybrid construction combines the non-combustibility and sound insulation of rock wool with the airtightness and thermal efficiency of polyurethane edge sealing. Concealed fasteners create a clean facade while reducing thermal bridges and water penetration.
Key Benefits
- Fire performance: non-combustible Class A core with typical fire-resistance options from 30 to 240 minutes, subject to panel construction and project certification.
- Thermal efficiency: typical rock wool thermal conductivity of approximately 0.038 W/m·K.
- Acoustic comfort: dense mineral fibers help reduce airborne and impact noise.
- Weather protection: concealed joints, four-sided tongue-and-groove options and PU-sealed edges improve airtightness and water resistance.
- Design flexibility: flat, micro-ribbed and box-ribbed finishes with multiple coating and color options.
- Fast installation: factory-prefabricated panels reduce site labor and shorten enclosure schedules.

Available Configurations
PU-Sealed Edge Rockwool Panel
High-pressure polyurethane foam seals the panel edges to improve airtightness, thermal continuity and moisture resistance.
Four-Sided Tongue-and-Groove Panel
Factory-formed end closures and interlocking joints provide a neat, tightly sealed facade suitable for modular installation.
Curved and Custom Corner Panels
Radiused, L-shaped and U-shaped corner units create continuous transitions and reduce dependence on exposed flashings.
Why Choose BeyondSpan
BeyondSpan supports coating selection, thermal and fire-performance requirements, profile optimization, detailing and project-specific production. Panels can be manufactured for corrosive, coastal and high-humidity environments using appropriate metallic coatings and PVDF finishes.
Frequently Asked Questions
Is a rockwool sandwich panel fireproof?
The mineral wool core is non-combustible. The complete panel fire rating depends on thickness, joint design, facings and tested assembly.
What panel thickness should I choose?
Common choices range from 50 to 200 mm. Climate, U-value target, span, wind load and fire-resistance requirements determine the final specification.
Can the panels be customized?
Yes. Width, length, thickness, surface profile, steel gauge, coating, color and corner details can be customized for the project.
