What is rock wool?

Rock wool is a porous material made from natural rocks such as basalt, diabase, etc., which are melted at high temperatures and then fiberized. Has excellent sound insulation, sound absorption, thermal insulation, fire resistance and other properties. Rock wool is not only widely used in ships and vehicles, but also in sound insulation treatment in fields such as construction, industry, and home furnishings. It is also widely used in the construction of our box houses. Rock wool is not only widely used for sound insulation in construction, industry, home and other fields, but also in ships and vehicles.

The porous structure and high density of rock wool make it have good sound absorption effect, which can effectively isolate noise of various frequencies and has excellent sound absorption performance. Its density is as high as 70kg/m3, which is rare in polyester sound-absorbing materials, so not only can sound absorption be expected, but also sound insulation can be expected.

Meanwhile, rock wool is a natural fire-resistant material with a high fire resistance limit, which can effectively prevent the spread of fire. And it has obtained fire certification, has self extinguishing function, and is a non flammable material.

Rock wool can effectively maintain indoor temperature and improve energy efficiency. Excellent insulation performance, keeping the room warm in winter and cool in summer, environmentally friendly and energy-saving. So rock wool board is also used as insulation board.

Rock wool has strong anti-aging and corrosion resistance, and can maintain its sound insulation effect for a long time. And it doesn't absorb water, so there's no need to worry about bead condensation. Even when used on floors and walls, the air layer can prevent water accumulation between the plywood and insulation layer, thereby preventing moisture and mold.
