Product Features
Lightweight and Flexible, Bending and Fitting: The exclusive 50kg/m³ low-density formula adopted by these mineral-wool-manufacturers endows the Basalt Wool Board with excellent elasticity and flexibility. The board can be slightly bent and closely installed along various curved surfaces, including large-diameter pipes (≥500mm) and circular storage tanks, without pre-cutting into small fragments, ensuring complete and seamless insulation coverage.
High Porosity, Low Airflow Resistance: Featuring abundant uniform fiber gaps, the Basalt Wool Board from trusted mineral-wool-manufacturers achieves high air permeability while maintaining stable thermal insulation. It is perfectly suitable for breathable insulation scenarios such as wooden structural walls and sloping roof slat layers, effectively preventing internal moisture condensation and long-term water accumulation.
Product Advantages
Reduced Load on the Main Structure: With a lightweight density of only 50kg/m³, this Basalt Wool Board is nearly 40% lighter than conventional 80kg/m³ insulation boards. As a high-cost-performance product from professional mineral-wool-manufacturers, it brings negligible extra load to building structures, making it ideal for roof insulation, light steel keel partition systems and old building renovation projects with strict load limits.
Quick Processing, Low Tool Wear: The flexible fiber structure of the mineral-wool-manufacturers’ Basalt Wool Board allows easy and fast cutting with ordinary utility knives. Its cutting efficiency is more than twice that of high-density fiber boards, reducing blade replacement frequency by 60%. Meanwhile, it produces far less construction dust on site, effectively optimizing the overall construction environment and improving project efficiency.
