75mm Thick Basalt Wool Board (100~120kg/m³)
This premium mineral-wool-china product, 75mm thick Basalt Wool Board, is professionally designed for engineering scenarios that demand single-layer, high-thickness thermal insulation and high-grade soundproofing performance. Manufactured with high-density pure basalt fiber with a typical density of 100~120kg/m³, this reliable mineral-wool-china insulation material greatly weakens heat conduction and sound transmission efficiency, while retaining stable A1 non-combustible fire resistance, meeting strict building thermal and acoustic insulation standards.

Product Features
Single-layer High Insulation Thickness: The 75mm thick Basalt Wool Board, a core mineral-wool-china insulation product, fully meets the exterior wall thermal conductivity requirement of K≤0.25 W/(m²·K) for extremely cold regions including Northeast China and Russia. It eliminates the need for double-layer board stacking, effectively reducing cold bridge phenomena at board joints and improving the overall thermal insulation integrity of the building envelope.
Superior Airborne Sound Insulation: Benefiting from the increased thickness and dense fiber structure of this mineral-wool-china board, it gives full play to the mass law of sound insulation. When filled in light steel keel partition walls, the 75mm Basalt Wool Board achieves a weighted sound insulation Rw of up to 55dB, efficiently blocking mid-to-high frequency noise such as neighbor conversations and TV sounds, creating a quiet indoor environment.
Product Advantages
Double Installation Speed: Compared with the traditional solution of laying two layers of 37mm or 38mm insulation boards, the 75mm integrated Basalt Wool Board only requires one-time laying and anchoring construction. This optimized mineral-wool-china application method cuts labor workload and auxiliary material costs by about 30% and shortens the overall construction period by half, greatly improving project delivery efficiency.
Stronger Thermal Stability: The thickened structure of the Basalt Wool Board forms a gentle internal temperature gradient. Under cyclic temperature changes ranging from -30℃ to 70℃, the internal structural stress of this mineral-wool-china insulation board is effectively controlled, avoiding common problems like delamination and warping. It features outstanding environmental adaptability and is extremely suitable for long-term stable operation of building exterior wall insulation systems.
