What Are Rockwool Sandwich Panels?
Composition and Structure
Rockwool sandwich panels are modern materials made for top performance. They have three layers. The middle layer, called the core, is made from rock wool. Rock wool comes from volcanic rocks like basalt and dolomite. This core is placed between two outer layers. These outer layers are usually coated with Galvalume or PPGI. Galvalume mixes zinc and aluminum to stop rust. PPGI uses zinc-coated steel to make it stronger.
The core gives great heat and sound insulation. Rock wool slows down heat transfer because it doesn’t conduct heat well. Its thick structure also blocks noise, making it good for quiet spaces. These panels are light, safe, and eco-friendly. They are strong and resist water, so they work in many climates.
Component/Property | Description |
|---|---|
Core Material | Made from basalt, dolomite, bauxite, slag, and reused mineral fleece. |
Outer Layers | Coated with Galvalume (half zinc, less than half aluminum) and PPGI (zinc-coated iron steel). |
Thermal Conductivity | Extremely low, improved with thicker Rockwool cores. |
R-value | Calculated based on thickness and conductivity, affecting heat loss resistance. |
Specific Heat Capacity | High capacity allows retention of more heat with temperature changes. |
Material Density | Thicker cores maintain high thermal mass, resulting in lower thermal conductivity. |
Characteristics | High compression strength, damp proof, environmentally friendly, excellent sound insulation, non-toxic, lightweight, and easy to install. |
Applications in Construction
Rockwool sandwich panels are used in many building projects. They are often added to walls, roofs, and ceilings because they insulate well. These panels are great for factories and warehouses. They help stop fires and block noise in these places.
In homes, these panels save energy by keeping heat inside. They also make rooms more comfortable by keeping temperatures steady. Schools and hospitals use them for safety and strength. Since the panels are light, they are easy and cheap to install.
The panels’ features make them very useful. Thicker cores give better insulation and soundproofing. For example, a 150 mm core reduces noise by 35 dB and has a U-value of 0.28 W/m²·K. This makes them perfect for tough conditions.
Sound Reduction Index (dB) | U Value (W/m²·K) | R Value (m²·K/W) | |
|---|---|---|---|
50 | 30 | 0.78 | 1.28 |
75 | 31.5 | 0.58 | 1.76 |
100 | 34 | 0.41 | 2.44 |
150 | 35 | 0.28 | 3.57 |
Using Rockwool sandwich panels ensures your buildings are safe and efficient. These panels are a smart choice for strong and eco-friendly construction.
Understanding Fire Resistance Ratings
What It Means and Why It Matters
Fire resistance ratings show how well materials handle fire. These ratings are important for keeping buildings safe. They tell us how long a material can stop fire, stay strong, and protect people. Materials with high ratings act as shields, giving more time to escape and reducing damage.
In building, fire resistance has different levels. Noncombustible materials don’t catch fire or burn. Ignition-resistant materials are made to handle fire risks. Fire-resistive systems stop fire from spreading in or between buildings. For example, fire-rated materials keep fire in one area, lowering its harm.
Tests like ASTM E119 and NFPA 285 measure fire resistance. ASTM E119 checks how long a material blocks fire. NFPA 285 looks at how flames spread on outside walls. These tests make sure materials are safe and work well during fires.
How Testing and Certifications Work
Testing fire resistance uses strict methods to check safety. Two main ways are used to rate fire resistance. The first way uses tested designs, following rules like ASTM E119 and ANSI/UL 263. These tests see how materials perform in controlled settings. The second way uses designs listed in codes, like Table 721 in the International Building Code (IBC). This table shows fire performance for certain materials.
Fire tests last for 30 minutes to 8 hours. During tests, materials face heat rising to 850°C in 20 minutes. This checks if they can handle heat and stay strong.
Certifications are also key for fire safety. Standards like NFPA 286 test flame spread and smoke inside buildings. ASTM E84 checks how fast flames spread on materials. These certifications prove materials meet safety rules, so you can trust them in a fire.
Fire Resistance Properties of Rockwool Sandwich Panels
Specific Ratings and Classifications
Rockwool panels are great at resisting fire. They are perfect for places where fire safety matters. These panels meet strict fire safety standards. For example, they follow FM Approved Class 1 rules. This means they are safe for walls and ceilings inside buildings. They also meet EN 13501-1, a European rule that rates materials like A1 and A2 as non-combustible. Another rule, EN 14509, checks insulated wall panels with metal faces in Europe.
These ratings show Rockwool panels are better at stopping fire than glasswool or synthetic cores. They can handle high heat without catching fire or spreading flames. This makes them important for keeping fires under control.
Classification Type | Description |
|---|---|
FM Approved Class 1 | Safe for walls and ceilings, meeting fire safety rules. |
EN 13501-1 | European fire rating system with classes like A1 and A2. |
EN 14509 | Checks insulated wall panels with metal faces in Europe. |
Performance Under Fire Conditions
Rockwool panels stay strong, insulated, and stable during fires. Their core material doesn’t burn, which helps them perform well. Tests exposed small samples to very high heat, up to 1002°C. Even then, the cooler side stayed at room temperature. This shows how well they block heat.
Studies prove Rockwool panels don’t break apart at 350°C. Synthetic cores fail at 250°C. Rockwool cores lose very little mass up to 300°C. They also stop flames from spreading and reduce heat transfer. This keeps people safe and protects buildings.
Important features include:
Low heat on the cooler side.
Strong panels that don’t bend or break.
No breaking apart or losing mass in high heat.
Rockwool panels are better than glasswool for fire safety. They resist heat and flames, making them the best choice for fire-safe buildings.
