Key Features of Leca Insulation Blocks
Thermal Insulation: Homogeneous insulation, approved by the National Fuel Consumption Optimization Organization, compliant with Chapter 19 of the National Building Regulations, and certified by the Building and Housing Research Center.
Sound Insulation: Compliant with Chapter 18 of the National Building Regulations and Iranian National Standard 8586.
Physical Workability: Leca blocks are easy to cut and nail, and can be drilled or grooved for cable and utility installations.
Fire Resistance: According to National Standard 12055 and BS EN 1363, provides 2 to 3 hours of resistance against direct flame exposure at temperatures up to 1200°C.
Compressibility: Rough texture on Leca lightweight aggregates, suitable water absorption, minimal thermal expansion, negligible shrinkage and swelling, preventing long-term cracking, and very low shrinkage, in accordance with ASTM standards.
Lightweight: Enables faster wall construction, ease of installing utilities, high earthquake resistance, and reduced mortar consumption.
Optimal Shape: Leca blocks are hollow and partially solid, preventing mortar wastage and offering a variety of shapes and sizes.
