Glass wool and rock wool products, manufactured with high- quality materials, are being used in various industrial sectors among which are construction, marine and automotive as well as in the agricultural sector where they are utilized as fertilizers and
In general, mineral wool products, such as glass wool and rock wool, have been playing a major role in the conservation and rationalization of energy, which significantly reduces toxic emissions affecting the entire planet’s temperature.
MINERAL WOOL CHARACTERISTICS
There are two basic types of mineral wool that are applied for insulation; and every type has its own characteristics. The user/applicator should be able to determine the right type to apply.
GLASS WOOL INSULATION
Glass wool is made of sand, recycled glass, limestone and soda ash. These are the same ingredients that are used to make familiar glass objects such as window panes or glass bottles. The glass is spun to form millions of fine fibers. A resin is used to bind the fibers together to form a mat of material. The density of the product determines whether the insulation is a lightweight quilt supplied in rolls, a flexible slab or a rigid slab, and thus determines its thermal insulation capacity.
• Long fiber, giving good tear strength
• Suitable for temperatures up to 400°C
• Available in rolls and slab
• Loft insulation
• Cavity wall insulation
• Sound insulation (absorption) within partitions and floors
ROCK WOOL INSULATION
Rock wool is mainly made of volcanic rock, typically basalt and/or dolomite. An increasing proportion is composed of recycled materials made from slag, and a waste product made from blast furnaces. The materials are melted and then spun into fine fibers. A resin is then used to bind the fibers together to form a mat of insulation.
• Short fiber – compressive strength
• Suitable for temperatures up to 850°C
• Denser than glass wool
• Available in the form of slabs, rolls and mattresses
• High compressive strength
• Thermal insulation of flat roofs, rain screen façades and external wall insulation
• Fire protection, including smoke and fire barriers
• High temperature applications
• Sound insulation for floors and walls
