Insulation Materials for Prefabricated Panel Houses
Common insulation materials for prefabricated panel houses include Expanded Polystyrene (EPS), Polyurethane Foam (PUR or PU), mineral wool board, Medium Density Fiberboard (MDF), Extruded Polystyrene (XPS), glass wool, rock wool, Extruded Expanded Polystyrene (XEPS), and Closed-Cell Polyurethane Foam (PIR), among others. Here is a detailed introduction to these materials:
Expanded Polystyrene (EPS): EPS is a lightweight material with excellent insulation properties, widely used in the thermal insulation layers of prefabricated houses. It not only provides outstanding thermal insulation but also offers resistance to water vapor penetration, effectively preventing moisture intrusion. Additionally, EPS is chemically resistant, moisture-proof, and sound-absorbing, making it a preferred choice for insulation in prefabricated panel houses due to its comprehensive performance.
Polyurethane Foam (PUR or PU): PUR or PU is a highly efficient thermal insulation material with high thermal insulation performance and strength. It can be used in the form of sandwich panels or spray coatings, providing excellent thermal insulation and sealing properties. In prefabricated houses, polyurethane foam effectively reduces heat transfer, enhancing the thermal insulation performance of the house.
Mineral Wool Board: Mineral wool board is made from mineral fibers and offers good thermal insulation and sound absorption properties. It can be used in walls, roofs, and floors, providing effective insulation and reducing noise transmission. In prefabricated panel houses, mineral wool board significantly improves living comfort.
Medium Density Fiberboard (MDF): MDF is made from fine wood shavings and adhesives, offering certain thermal insulation properties. It can be used inside walls or in the production of sandwich panels, providing good thermal insulation. Additionally, MDF has some structural strength and can be used for partial structural support in prefabricated houses.
Extruded Polystyrene (XPS): XPS is a high-density polystyrene foam with high strength and compressive resistance. It is suitable for prefabricated house projects requiring higher thermal insulation performance, such as cold storage warehouses. In ordinary prefabricated panel houses, XPS also provides excellent thermal insulation.
Glass Wool (Glass Fiber): Glass wool is made from glass fibers and offers excellent thermal insulation and sound absorption properties. It is commonly used in the thermal insulation layers of walls, roofs, and floors, effectively reducing heat transfer and noise interference. In prefabricated houses, glass wool is an important material for enhancing thermal insulation and soundproofing performance.
