Hey there! As a supplier of Rock Wool Sandwich Wall Panels, I often get asked about the technical parameters of these panels. So, I thought I'd put together this blog post to give you all the deets.
1. Dimensions
The first thing we need to talk about is the size of the rock wool sandwich wall panels. These panels come in a variety of lengths, widths, and thicknesses to meet different construction needs.
Length
Typically, the length of rock wool sandwich wall panels can range from 2 meters to 12 meters. The longer panels are great for large - scale construction projects where fewer joints are desired, which can improve the overall structural integrity and reduce the risk of leakage.
Width
The standard width of these panels is usually around 950mm or 1150mm. This width is designed to be easy to handle during installation and also fits well with common construction layouts.
Thickness
The thickness of rock wool sandwich wall panels varies widely, from 50mm to 250mm. Thicker panels offer better insulation and sound - proofing properties. For example, a 50mm thick panel is suitable for areas with mild climate conditions where basic insulation is required. You can check out the 50mm Thickness Clean Panel on our website for more details.
2. Core Material - Rock Wool
The core of the rock wool sandwich wall panel is, of course, rock wool. Rock wool is made from natural basalt or diabase, which are melted at high temperatures and then spun into fibers.
Density
The density of the rock wool core can range from 80kg/m³ to 200kg/m³. A higher density rock wool core provides better insulation, fire resistance, and mechanical strength. For instance, in industrial buildings where there are strict fire safety requirements, a higher - density rock wool core is often preferred.
Thermal Conductivity
One of the most important properties of rock wool is its low thermal conductivity. The thermal conductivity of rock wool used in our panels is usually between 0.032W/(m·K) and 0.040W/(m·K). This means that the panels can effectively prevent heat transfer, helping to keep the indoor temperature stable and reducing energy consumption for heating and cooling.
Fire Resistance
Rock wool is a non - combustible material, and it has excellent fire - resistant properties. Our rock wool sandwich wall panels can achieve a fire - resistance rating of up to 4 hours, depending on the thickness and construction of the panel. This makes them a great choice for buildings where fire safety is a top priority, such as hospitals, schools, and industrial warehouses.
3. Face Materials
The face materials of rock wool sandwich wall panels play an important role in protecting the core and providing an aesthetic finish.
Metal Sheets
Commonly, the face materials are metal sheets, such as galvanized steel, color - coated steel, or aluminum. Galvanized steel sheets offer good corrosion resistance, while color - coated steel sheets come in a variety of colors, allowing for a more visually appealing exterior. Aluminum sheets are lightweight and also have good corrosion resistance.
Thickness of Face Materials
The thickness of the metal face sheets can range from 0.3mm to 1.0mm. Thicker face sheets provide better mechanical strength and durability. For example, in areas with high wind loads or where the panels may be subject to physical impact, a thicker face sheet is recommended.
4. Mechanical Properties
Compressive Strength
The compressive strength of rock wool sandwich wall panels is an important parameter, especially for load - bearing applications. Our panels can have a compressive strength of up to 100kPa, which means they can withstand a certain amount of vertical pressure without being damaged. This makes them suitable for use in multi - story buildings or as partition walls in industrial facilities.
Bending Strength
The bending strength of the panels determines their ability to resist bending forces. Our rock wool sandwich wall panels have good bending strength, which allows them to be installed over relatively long spans without sagging. This is crucial for maintaining the flatness and appearance of the walls.
5. Sound Insulation
In addition to insulation and fire resistance, rock wool sandwich wall panels also offer good sound - insulation properties. The porous structure of the rock wool core can effectively absorb sound waves, reducing noise transmission between different spaces. The sound - insulation performance of our panels can reach up to 45dB, which is sufficient for most commercial and residential applications.
6. Clean Room Applications
We also offer rock wool sandwich wall panels for clean room applications. Our Mechanical Clean Room Panel and Manual Clean Room Panel are designed to meet the strict requirements of clean rooms, such as low particle emission, high cleanliness, and good air - tightness. These panels are widely used in industries like electronics, pharmaceuticals, and food processing.
Conclusion
So, there you have it - the main technical parameters of rock wool sandwich wall panels. Whether you're building a commercial building, an industrial facility, or a clean room, our rock wool sandwich wall panels can provide you with excellent insulation, fire resistance, sound - proofing, and mechanical properties.
