Mineral Wool is made from melted basalt rock in a furnace at high temperatures. The rock melts into long strands of insulation that are then bonded together using a solution of oils and resins. These binder solutions often contain formaldehyde, which is a concern for some homeowners. However, manufacturers are developing alternatives. Mineral Wool is an insulation made of spun yarns made from melted glass or stone. The threads are combined in a specific way to create a woolly structure. The result is then compressed into boards or rock wool batts that serve as insulation. It can also be blown in hollow spaces like cavity walls as loose wool. It is a non-combustible material and it does not release toxic gases when exposed to extreme heat. It helps slow the spread of fire, giving residents time to escape and firefighter’s time to save lives. It is also very durable. This means that clients can expect a long lifespan of their new insulation. It also makes it easy for builders to make precise cuts around outlets, pipes or any other obstructions in a wall. Mineral Wool insulation prevents convection by entrapping air in its open-cell, woolly matrix. This static air is much less conductive than injected gas, which is why it is so good for insulation. Mineral wool is made using recycled materials like slag and glass. This helps reduce the building’s environmental footprint and makes it one of the most sustainable insulators on the market. The starting material used for the present mineral wool can include one or several recyclable materials, as well as a virgin mineral. The resulting mineral wool product should have an A/B ratio that falls within a specified range. Mineral Wool, made from tough materials such as recycled steel slag and raw basalt is an eco-friendly insulation product. It contains an average of 75% post-industrial recycled content and does not require the use of chemical fire retardant additives that present a health hazard. Its rigid shape fills stud voids better than fiberglass batts and it does not sag or settle, retaining its R-Value over time. It can be installed over existing drywall and is compatible with most framing systems. Rockwool insulation helps to save energy for heating and cooling by preventing heat loss from the walls, floors and roof of a building. This lowers the need for primary energy, the emission of harmful substances and contributes to an environment sustainable protected. It also enhances acoustic performance, keeping noise inside the living spaces and out of public areas. Mineral Wool can be used in a variety of ways, including as a vapor barrier in walls and in roofs, and as a fire retardant in cladding systems such as curtain walls and spandrel panels. It was once the most widely used insulation, whereas it has been displaced by fiberglass batts and other materials. It can be manufactured as semi-rigid batts, sheets, and loose-fill; it's available in R-values similar to fiberglass. Most modern Mineral Wool insulation is made by cooking a mix of basalt or dolomite rock and slag, which is a byproduct of steel production, in a furnace until it becomes liquefied. The molten rock or slag is then spun in a process that has been likened to spinning cotton candy, leaving long, thin fibers that are densely packed together. These fibers are then bound with a solution of oils and resins. It is composed of a long-chained, randomly oriented mineral fiber that is similar to volcanic ash or sea shells, mineral wool insulation has excellent thermal properties. It is also effective in reducing sound transmission, although it does not have the same level of acoustical performance as fiberglass insulation. Get the Press Release of Mineral Wool
