Infill panels are materials used to fill gaps or spaces within a structure. They are installed between the floors of a building’s main structural framework to support the cladding system. These panels are also used to create partition walls within the interior, enhancing the building’s soundproofing and fire resistance. Infill panels are commonly used in construction to complete the exterior or interior of a building and are non-load-bearing.
Sandwich Panel
Expanded Polystyrene (EPS) Sandwich Panels
EPS sandwich panels typically consist of two outer layers made of thin steel sheets, aluminum, or other materials, with an EPS foam core sandwiched in between. The EPS core provides excellent thermal insulation, offering superior insulation properties, good compressive strength, and lightweight characteristics. Additionally, EPS sandwich panels offer excellent thermal and sound insulation, along with good fire resistance.
Rigid Polyurethane (PU) Sandwich Panels
PU sandwich panels have outer layers made of steel sheets, aluminum, or other materials, with a PU foam core in the middle. The PU foam core offers excellent thermal insulation properties, making it an effective barrier against external heat, helping to maintain stable indoor temperatures. PU foam is a lightweight material with high thermal insulation capabilities, featuring a low thermal conductivity that effectively isolates heat. PU sandwich panels are relatively lightweight, making them easy to transport and install, while also providing high strength and stability.
Rock Wool Sandwich Panels
Rock wool sandwich panels have outer layers made of galvanized steel, aluminum, or other weather-resistant materials, with a core made of rock wool fibers, which are produced by melting natural rock. Rock wool offers exceptional fire resistance, remaining stable and non-combustible even in high-temperature environments, meeting many building fire safety standards. These panels provide both insulation and fire protection, enhancing the energy efficiency and safety of buildings. Installation of rock wool sandwich panels is relatively straightforward, typically involving lifting and securing them in place.
Extruded Polystyrene (XPS) Sandwich Panels
Extruded Polystyrene (XPS) sandwich panels typically feature outer layers made of steel sheets, aluminum, or other weather-resistant materials. The core consists of XPS foam, a type of polystyrene foam produced through an extrusion process. XPS foam offers excellent thermal insulation and structural strength, with a closed-cell structure that ensures low water absorption, maintaining stable insulation performance. XPS sandwich panels have high compressive strength, making them suitable for load-bearing applications such as floors and roofs.
Foam Metal Sandwich Panels
Foam metal sandwich panels are high-performance composite materials consisting of two outer metal sheets and a foam metal core. The foam metal core is a porous material made from metals like aluminum, copper, or nickel through specialized processes. This unique structure combines lightweight properties with high strength, offering excellent fire resistance and being non-combustible. The porous nature of the foam metal also contributes to sound absorption and noise reduction, enhancing indoor comfort.
Polyester Foam Sandwich Panels (PF Sandwich Panels)
Polyester foam sandwich panels, often abbreviated as PF sandwich panels, are composite materials with a polyester foam core. The outer layers are typically made of galvanized steel, aluminum, or other metal materials. The polyester foam core is a synthetic material that offers excellent thermal insulation and lightweight properties. PF sandwich panels are known for their good corrosion resistance and moisture-proof performance, making them suitable for various applications where these characteristics are essential.
Color-Coated Corrugated Sheets
Color-coated corrugated sheets, also known as color-coated panels, are formed by cold rolling and bending to create various waveforms. The base material is typically galvanized steel, aluminum, or stainless steel. These base materials undergo corrugation to form different patterns, such as waves, ridges, or other designs, to meet specific design and functional requirements. The galvanized and coated base materials offer excellent corrosion resistance, ensuring stability and durability in various climate conditions.
Silicate Board
Silicate board is a building material primarily composed of silicate minerals, typically made from calcium silicate or other silicate compounds through high-temperature and high-pressure processing. The main components of silicate boards are calcium silicate or magnesium silicate, which combine with water under high-temperature and high-pressure conditions to form a rigid board. Silicate boards offer exceptional fire resistance and thermal insulation, making them ideal for applications requiring high levels of fire protection and heat isolation.
Gypsum Board
Gypsum board is a commonly used building material for wall and ceiling decoration and partitions. The core material of gypsum board is gypsum, typically produced by heating and dehydrating natural gypsum ore into a powder, which is then mixed with water to form a slurry and molded into boards. Gypsum board is widely used due to its ease of installation, good sound insulation, fire resistance, environmental friendliness, and smooth surface finish. It is a prevalent and effective material in interior walls, ceilings, partitions, and suspended ceilings.
Concrete Slab
Concrete slabs are structural building materials primarily composed of a mixture of cement, sand, gravel, and water. They are formed by pouring, vibrating, and curing to create solid slabs. Concrete slabs are widely used in the construction industry for various structural applications, including floors, ceilings, and walls. Known for their high strength, fire resistance, durability, and good sound insulation properties, concrete slabs are extensively utilized in building structures.
Aluminum Composite Panels (ACP)
Aluminum composite panels are composite materials made of an aluminum alloy layer and a plastic core layer. The surface layer of the aluminum composite panel is typically made from 0.5-0.6 mm thick aluminum alloy, which is treated with a coating that provides a wide range of colors and textures, as well as good weather resistance and corrosion resistance. The core layer is usually made of polyethylene or fire-resistant materials, offering excellent thermal insulation and soundproofing properties. The backing layer is typically aluminum alloy or another type of protective layer that enhances the structural stability and adhesion of the panel. Due to its excellent decorative qualities, strength, and durability, aluminum composite panels are widely used in building facades, interior decoration, and other construction and decorative applications. Metal facades deliver modern style and durability.
Conclusion
Infill panels play a crucial role in steel structure buildings, enhancing both the functionality and aesthetics of the construction while also influencing the structure’s safety and comfort. In steel-framed factories, infill panels can increase the rigidity and stability of floors, improving the building’s resistance to earthquakes, wind, and fire. Additionally, they contribute to the overall comfort and safety of the facility. The choice of materials and design for infill panels depends on factors such as structural requirements, thermal insulation and soundproofing needs, and aesthetic preferences.
