Thermal Insulation Materials for Prefabricated Houses

The thermal insulation materials available for prefabricated houses mainly include foam concrete, XPS extruded polystyrene board, rock wool board, foamed cement insulation board, aerogel, aluminum foil insulation cotton, polyurethane insulation material, graphite polystyrene sandwich composite board, fireproof phenolic foam insulation board, etc. Here is a detailed introduction:

Foam concrete has a thermal conductivity ranging from 0.08 to 0.18 and a fire rating of Class A, indicating excellent fire resistance. It can effectively prevent the spread of fire and ensure the safety of the house. Additionally, its relatively low price makes it a good choice for prefabricated house projects with limited budgets. However, its compressive strength is relatively weak, and care should be taken to avoid excessive compression during installation and use.

XPS extruded polystyrene board has a very low thermal conductivity of 0.028 and excellent moisture resistance, making it highly suitable for use in damp environments such as basements. It can effectively prevent moisture penetration and keep the interior dry. However, its high price increases costs. Moreover, when selecting, it is necessary to choose Class B fire-resistant products to meet fire safety requirements.

Rock wool board is heat-resistant and will not burn even at temperatures as high as 450 degrees Celsius. It also has sound-absorbing properties, reducing indoor noise. However, it is prone to absorbing water, and in humid southern regions, proper sealing treatment is essential to prevent it from affecting its thermal insulation performance and service life.

Foamed cement insulation board can have the same lifespan as the building and bonds firmly during construction, ensuring long-term stable thermal insulation performance. However, its impact resistance is poor, and it should be protected from external forces during installation and use.

Aerogel has a thermal conductivity of only 0.018, providing exceptional thermal insulation. It is one of the solid materials with the lowest known thermal conductivity. However, its high price makes it generally suitable for special prefabricated house projects with extremely high thermal insulation requirements and sufficient budgets.

Aluminum foil insulation cotton has multiple functions such as fire resistance, water resistance, sun protection, thermal insulation, sound insulation, and noise reduction, meeting various needs of prefabricated houses in different environments.

Polyurethane insulation materials, such as polyurethane black and white materials, are commonly used for roof thermal insulation and have certain flame-retardant properties, effectively improving the fire safety of the house.

Graphite polystyrene sandwich composite board is mainly used for roof thermal insulation and has good thermal insulation performance, providing a comfortable indoor environment for the house.

Fireproof phenolic foam insulation board has moisture-resistant, fire-resistant, and thermal insulation functions, making it suitable for roof thermal insulation and effectively protecting the house from external environmental influences.
