Images of Insulation Boards for Prefabricated Houses

Although we cannot directly provide images of insulation boards for prefabricated houses, we can offer detailed descriptions of their appearance, types, and characteristics to help you form a clear understanding.

Insulation boards for prefabricated houses are commonly used energy-saving materials in modern construction. Their core function is to reduce indoor and outdoor heat exchange by blocking heat conduction, convection, and radiation, thereby improving building energy efficiency. Depending on the material and structure, insulation boards can be classified into the following types, each with distinct appearances and performance characteristics:

1. Polystyrene Foam Boards (EPS/XPS)

• Appearance: Typically white or light-colored flat panels with a smooth surface and neat edges, ranging in thickness from 10mm to 100mm. XPS boards (extruded polystyrene) have a higher density and smoother surface, while EPS boards (expanded polystyrene) have fine pores on the surface.
• Characteristics: Lightweight, waterproof, and low-cost, but with poor heat resistance and potential aging when exposed to UV light for extended periods. Commonly used for insulation layers in walls, roofs, and floors.

2. Polyurethane Foam Boards (PU)

• Appearance: Mostly rigid foam boards in various colors (e.g., yellow, gray), with surfaces that can be covered with aluminum foil or fiberglass cloth to enhance performance. Thickness typically ranges from 20mm to 150mm.
• Characteristics: Extremely low thermal conductivity, excellent insulation performance, and具备一定的强度 (certain strength) and fire resistance. Suitable for low-temperature environments (e.g., cold storage) or buildings with high insulation requirements.

3. Mineral Wool Boards (Rock Wool/Glass Wool)

• Appearance: Light yellow or grayish-white, with a loose and porous texture, and possibly covered with a moisture-proof film on the surface. Thickness can be customized, ranging from 30mm to 200mm.
• Characteristics: High fire rating (Class A non-combustible), effective sound absorption and noise reduction, but highly absorbent and requiring a moisture-proof layer. Commonly used for insulation in steel structure factories and exterior walls of high-rise buildings.

4. Phenolic Foam Boards

• Appearance: Dark red or brown rigid panels with a smooth surface and neatly cut edges, typically ranging in thickness from 20mm to 100mm.
• Characteristics: Heat-resistant (up to 180°C), low smoke and non-toxic, with superior fire performance compared to polystyrene and polyurethane, but higher cost. Suitable for places with strict fire safety requirements, such as hospitals and schools.

5. Vacuum Insulation Panels (VIP)

• Appearance: Ultra-thin design (thickness of only 5mm-30mm), with a metallized film or composite material surface and sealed edges.
• Characteristics: Extremely low thermal conductivity (only 1/10 of traditional materials), but expensive and requiring protection from punctures or bending. Commonly used in refrigerators, cold chain logistics, or ultra-low-energy buildings.

Selection Recommendations:

• Limited Budget: Prioritize EPS or XPS boards for cost-effectiveness.
• High Fire Safety Requirements: Choose rock wool or phenolic boards.
• Limited Space: Consider vacuum insulation panels or high-density PU boards.
• Humid Environment: Use with a moisture-proof layer or select XPS boards.
