8 cm 150 kg/m³ Rock Wool: Superior Strength and Professional-Grade Insulation

In insulation systems, both thickness and density play a critical role in determining overall performance. 8 cm 150 kg/m³ rock wool combines a high-density structure with an 8 cm thickness to deliver exceptional resistance to heavy loads, impact, and compression while providing outstanding thermal and acoustic insulation.

It is widely used in industrial facilities, exterior wall insulation systems, passive fire protection projects, roofing applications, and high-performance acoustic environments.

What is 8 cm 150 kg/m³ Rock Wool?

This insulation board is manufactured from melted basalt rock fibers and features a density of 150 kg/m³ with a thickness of 8 cm. Its high-density construction significantly improves mechanical strength while offering superior sound absorption and thermal insulation.

The material is also classified as A1 non-combustible, making it an excellent choice for projects where fire safety is a primary concern.
