Is the external wall insulation composite aluminum foil rock wool board 20mm thick? The composite aluminum foil rock wool board (20mm thick) is an insulation board made of high-density hydrophobic rock wool as the core material, with one or both sides covered with high reflectivity aluminum foil (usually embossed aluminum foil). It is commonly used for thermal insulation, moisture prevention, and energy conservation in areas with limited space.
The 20mm-thick exterior wall insulation composite aluminum foil rock wool board is a multifunctional building lining material that integrates "fire resistance, moisture resistance, sound absorption, and lightweight". It excels in addressing the pain points of fire safety and moisture vapor barrier, and also provides auxiliary insulation effects. If higher energy efficiency is pursued, it is usually necessary to choose thicker (such as over 50mm) rock wool boards or use them in combination with other primary insulation systems. Application scenarios of composite aluminum foil rock wool board (20mm thickness for reasonable use):
Local reinforcement and insulation for structural cold bridge areas such as beams, columns, and window frames;
Lining board on the inside of the curtain wall;
Indoor partition wall anti-condensation layer;
Industrial equipment and pipeline cladding;
Space-constrained areas in the renovation of old houses.
