9,560 m² Rock Wool Sandwich Wall Panel Order for Guatemala
When a Guatemalan industrial developer required a fire-rated wall envelope for a large-scale warehouse project, LIAOHE supplied 9,560 m² of rock wool sandwich wall panels in a single factory-direct order. The project combined A-grade fire performance with coordinated export logistics from LIAOHE’s Shandong manufacturing base.
Project Overview
| Project market | Guatemala |
| Application | Industrial warehouse walls |
| Total panel area | 9,560 m² |
| Panel type | Rock wool sandwich wall panels |
| Panel thickness | 50 mm |
| Outer steel sheet | 0.50 mm, HDP coated |
| Inner steel sheet | 0.40 mm |
| Rock wool density | 120 kg/m³ |
| Fire rating | A1 non-combustible |
Why Rock Wool Wall Panels for This Project?
The Guatemalan project’s building code required non-combustible wall materials for the warehouse envelope. Rock wool sandwich panels with A1 fire rating met this requirement while also providing thermal insulation for the building’s internal climate control.
Key specification decisions included:
- 50 mm thickness — sufficient insulation for the local climate while keeping wall weight manageable
- 120 kg/m³ rock wool density — ensures compressive strength and dimensional stability across large wall spans
- HDP-coated steel facing — provides UV and weather resistance for long-term exterior exposure
- Wall-specific joint geometry — designed for vertical installation with concealed fasteners
Production and Quality Control
The order was produced on LIAOHE’s dedicated rock wool wall panel line. Each bundle was checked for panel thickness, steel adhesion, edge geometry, and surface finish before moving to the packing area.
Export Packing and Container Loading
The complete order was packed in wrapped bundles with wooden bases, corner edge protectors, and inter-panel separators to prevent transit damage. Container loading was coordinated in LIAOHE’s factory yard with wooden bracing and tension straps inside 40HQ containers.
Supply Scope
- 9,560 m² rock wool sandwich wall panels (50 mm, A1 fire-rated)
- Custom panel lengths per project wall-drawing schedule
- Export packing with protective wrapping and wooden bases
- Container loading coordination and bracing
- Fire-rating certification and test documentation
Project Outcome
The panels were produced and shipped on schedule. The factory-direct supply model allowed the Guatemalan buyer to review production progress, packing methods, and fire-rating documentation before container departure, reducing procurement risk for the warehouse project.

FAQ
Why choose rock wool for industrial warehouse walls?
Rock wool provides A1 non-combustible performance, which is often required by fire codes for large industrial buildings. It also provides thermal and acoustic insulation.
What is the typical rock wool density for wall panels?
Wall panels commonly use 100–120 kg/m³ rock wool density. Higher density improves compressive strength and dimensional stability for tall wall installations.
Can LIAOHE supply similar panels to other Central American countries?
Yes. LIAOHE regularly exports to Guatemala, Costa Rica, El Salvador, and other Central American markets with appropriate export documentation and container logistics.
What certification is available for rock wool fire-rated panels?
LIAOHE provides A1/A2 fire-rating test reports, CE certification, and CPR compliance documentation according to the destination market’s requirements.
