Mineral wool is often used as an insulation material because of its suitable material properties. It is easy to handle, and rock wool board products are cheap in the construction industry. Due to its characteristics of safety, sound insulation, high performance, etc., it benefits the construction industry. There are now a large number of materials on the market for wall insulation of residential or commercial infrastructure. In the past few decades, one material that has become increasingly popular is mineral wool. As the name suggests, mineral wool is a mixture of stone, molten gas or industrial waste. Mineral wool is a versatile and unique product, commonly used as an insulation material. The excellent thermal performance of mineral wool has made a great contribution to combating climate change and saving energy. In addition, the structure of mineral wool gives it a unique ability to improve safety by reducing fire risk and combating noise pollution.
Two types of mineral wool products are:
Glass wool insulation, glass wool is made from recycled glass or sand, soda ash and limestone, its composition is similar to glass items such as glass bottles or window glass.
Rock wool insulation, rock wool is made from basalt, volcanic rock and more recycled materials in the form of coal briquettes. Inorganic slag or rock is the main component of rock wool, containing 98%. And the remaining 2% organic matter is usually thermosetting resin binder and a small amount of oil. Potential benefits of mineral wool, since mineral wool is one of the common insulation materials produced around the world, it has various potential benefits. Listed below are some reasons why mineral wool is becoming increasingly popular in the construction and building industry.
Easy to install, mineral wool is very flexible and lightweight, and can also be fixed between metal frames, rafters and wood without additional fixings. Therefore, workers find it easy to handle and install. However, with new manufacturing methods, many manufacturers have now made products easier to handle without affecting performance.
Wide range of uses, with mineral wool various requirements can be met. It can be used for roofs, attics, cavity walls, pipes, structured walls and solid walls.
Fire protection, mineral wool will not support combustion and will not spread flames because it is almost non-combustible. Buildings using mineral wool automatically improve their fire safety.
High acoustic performance, the elastic and porous structure of mineral wool enables it to absorb sound. Mineral wool may be the best solution for excessive noise transmission between rooms or between neighbors.
High thermal performance, mineral wool can withstand temperatures up to 400°C, so it provides incredible high thermal performance. This makes it the perfect material for insulation in energy plants and factories.
Can use recycled materials, since glass is the main raw material for manufacturing mineral wool, it can be made from recycled components. For example, use as much glass (86%) as possible in its manufacturing process.
Reduce carbon dioxide emissions, installing thick-size (270mm) mineral wool in an uninsulated attic can typically save up to 800 kg of carbon dioxide per household per year. Therefore, mineral wool improves the environmental efficiency of the home and also helps reduce energy demand, thereby saving fuel for customers.
