Ecoin exterior wall rock wool board/lamella are specially designed and produced for the thin plastered external insulation systems of the exterior walls of buildings. With easy plastering and construction, they are applicable to the construction of compact structures with concrete or brick foundation walls, or the energy-saving reconstruction of existing buildings. The application of mineral wool boards as the insulation systems of exterior wall complies with the needs of the fire laws and regulations of ASTM.

Exterior Wall Rock Wool Board FAQ
Below are the questions buyers ask most before ordering. Each answer comes from our production team.
The rock wool board is produced at 120-180 kg/m3, while the lamella version runs 100-120 kg/m3. Rock wool board thickness ranges from 25 mm to 100 mm, and dimensions of each rock wool board can be customized.
Yes. Made from molten basalt fiber, this rock wool board is Class A1 non-combustible according to EN 13501-1. Learn more about mineral wool as an insulation category.
The rock wool board’s high compressive strength and tensile strength make it ideal for thin plastered external insulation systems (ETICS), combining the thermal performance, sound absorption, and water repellency a quality rock wool board should deliver. See our full mineral wool product range for more rock wool board options.
Rock wool board packs are heat-shrink wrapped on pallets. Normal rock wool board production and delivery time is 7-15 days, with TT, LC, and Western Union accepted. For large projects we can arrange weekly partial shipments so the rock wool board arrives on site in step with your installation schedule, reducing storage needs and protecting the boards from moisture before use.
EcoIn has manufactured the rock wool board in China since 1995, so every rock wool board order is factory-direct. Our QC team inspects each rock wool board batch for density and fire performance, and our engineers help you choose the right rock wool board spec for your wall system.
Exterior wall insulation boards are commonly specified against EN 13162 for factory-made mineral wool products, EN 13501-1 for reaction-to-fire classification, and ASTM C612 for board-type thermal insulation. Key parameters to confirm on the datasheet are thermal conductivity (typically 0.036-0.040 W/(m·K) at 25°C), compressive strength at 10% deformation (40 kPa or higher for render systems), tensile strength perpendicular to faces (7.5-15 kPa depending on the system), water repellency (hydrophobic treatment with short-term water absorption below 1 kg/m²), and dimensional stability.
For mechanical fixing, pull-through resistance of the anchor against the board surface should also be tested. EcoIn provides full test reports with every shipment, including third-party certificates, so your local building authority can verify compliance before installation begins. Custom sizes outside the standard 600 x 1200 mm format are available on request for special facade layouts.
