Thermal Insulation Materials
1. Rockwool Insulation
Rockwool is a widely used brand in thermal insulation for both industrial applications and residential and building insulation. Rockwool's headquarters are located in Copenhagen, Denmark, with 45 manufacturing plants across Europe, North America, and Asia. In Thailand, Rockwool products are manufactured by Rockwool Thailand.
Rockwool products are made from basalt, or volcanic rock, with non-combustible properties and a melting point of over 1,000°C. It is suitable for heat, fire, and sound insulation. Though made from rock, it has a wool-like texture similar to natural wool insulation. The raw materials used are limestone and basalt, which are melted at around 1300°C. The molten materials are spun into fibers, which are coated with a thermosetting binder. After curing, the fibers are bonded into sheets and cut into various sizes.
Rockwool insulation is effective in temperatures ranging from -240°C to +820°C, making it highly efficient for both heat and sound insulation. Rockwool Cool n Comfort is commonly used for wall and ceiling insulation, helping to reduce heat transfer in buildings and reducing air conditioning costs.
For sound insulation, Rockwool offers four models: Safe ‘n’ Silent Pro330, Safe ‘n’ Silent Pro350, and Safe ‘n’ Silent Pro370, available in thicknesses of 50, 75, and 90 mm. These products are widely used in hospitals, malls, cinemas, office buildings, and industrial facilities.
2. Ceramic Fiber Insulation
Ceramic fiber, also known as ceramic glass fiber or ceramic thermal insulation, is a high-temperature material used for thermal insulation at temperatures ranging from 1,260°C to 1,600°C. It is commonly used for applications like furnaces, ovens, and kilns. Ceramic fiber is non-combustible and is ideal for industrial heat insulation. It is available in different forms, such as blankets, and is used to insulate heat-sensitive structures like ovens and heat pipes.
3. Microfiber Insulation
Microfiber insulation is produced in Thailand, using 100% recycled glass as the primary raw material. Its yellow color comes from natural materials during the production process.
A key feature of microfiber insulation is its Non-Water Absorption property, which prevents moisture from entering. It is environmentally friendly, earning a green label, and has minimal environmental impact. Certified by IARC, microfiber insulation is available in both roll and sheet forms, suitable for high-temperature applications up to 350°C. It is durable, easy to install, and commonly used for heat insulation in hot air ducts, oven walls, and boiler walls.
Cold Insulation Materials
1. EPDM Rubber Insulation
EPDM rubber insulation is made from special elastomeric rubber, containing many independent air cells. This structure provides excellent water and vapor resistance, low thermal conductivity, and high durability against ozone, UV rays, and various weather conditions. It is highly flexible and easy to install. EPDM rubber insulation is ideal for chilled water systems and air conditioning pipes, helping reduce energy loss and prevent condensation. Popular brands include Armaflex and Aeroflex.
