A1 Fireproof Thermal Insulation Material Grade Selection Guide
A1 thermal insulation material selection should be based on project environment, fire safety requirement, thermal conductivity target, bulk density, compressive strength, operating temperature, and installation structure. Different Ulite grades should not be treated as identical products.
| Selection Requirement | Recommended Direction | Why It Matters |
| Lightweight insulation layer | Consider lower-density grades such as Ulite-1510 or Ulite-2010 | Helps reduce system weight while maintaining basic insulation performance. |
| Stronger local compression resistance | Consider higher-density grades such as Ulite-3010 or Ulite-3810 | Improves pressure-bearing capability and installation stability. |
| Better thermal insulation priority | Compare thermal conductivity values from 0.040±0.03 to 0.068±0.03 W/m·K | Lower thermal conductivity supports better heat transfer reduction. |
| Building fireproof insulation | Use Class A1 rated material with suitable thickness and installation method | Helps meet non-combustible fireproofing requirements. |
| High-temperature equipment protection | Check operating temperature range and limit temperature | Helps avoid material mismatch under long-term thermal exposure. |
| Cryogenic or cold insulation use | Check low-temperature stability and installation continuity | Helps reduce cold loss, condensation risk, and thermal bridge issues. |
Note:
Final selection should be verified through sample testing and installation simulation, especially for large building projects, industrial equipment, high-temperature pipelines, LNG systems, and cryogenic insulation projects.
How to Choose the Right A1 Fireproof Thermal Insulation Material?
Select the right Ulite grade based on thermal conductivity, bulk density, compressive strength, fire rating, operating temperature, installation structure, and project environment. Choosing only by thickness or density may lead to heat loss, poor load performance, installation mismatch, or long-term durability issues.
Lower Density Requirement
Higher Compressive Strength
Lower Thermal Conductivity
High / Low Temperature Application
Key Selection Factors for A1 Fireproof Thermal Insulation Material
Bulk Density
Bulk density ranges from 0.09±0.02 to 0.23±0.02 g/cm³. Lower-density grades help reduce system weight, while higher-density grades usually provide stronger compressive performance.
Compressive Strength
Compressive strength ranges from ≥0.7 MPa to ≥2.7 MPa by grade. It should be considered when the material is used in areas requiring local pressure resistance, panel stability, or installation reliability.
Thermal Conductivity
Thermal conductivity ranges from 0.040±0.03 to 0.068±0.03 W/m·K at 23°C. This value directly affects insulation efficiency and heat transfer reduction.
