Thermal Conductivity
(K-Value) The lower the value, the better the insulation performance |
0.018–0.023 W/m.K | 0.030–0.037 W/m.K | 0.035–0.038 W/m.K | 0.039–0.045 W/m.K |

| Condensation Around the Covered Material | No condensation occurs because the insulation is bonded directly to the roofing sheet. PU/PIR also provides excellent adhesion to steel materials. | Condensation may occur due to the gap between the insulation layer and the roofing sheet. | Condensation may occur due to the gap between the insulation layer and the roofing sheet. | Condensation may occur due to the gap between the insulation layer and the roofing sheet. |
| Chemical Resistance | Resistant to acids and alkalis | Resistant to acids and alkalis | Resistant to acids and alkalis | Resistant to acids and alkalis |
| Compressive Strength | Lightweight and provides the highest strength compared with other insulation materials of the same density. | The insulation is soft, requires higher density, and is susceptible to compression. | The insulation is soft and easily compressed because it is manufactured from layered fibers. | The insulation is soft and easily compressed because air is trapped within the material. |
| Fire Performance | Combustible but does not support flame spread. PIR provides better fire resistance than PU.* | Combustible and deteriorates within a short period. | The adhesive used to bond the insulation to the roofing sheet may burn, while the insulation itself is non-combustible. | Combustible and deteriorates within a short period. |
| Sound Absorption | Good sound absorption | Moderate sound absorption | Excellent sound absorption | Moderate sound absorption |

Resistance to Water, Moisture,
and Air Infiltration |
Excellent resistance to water infiltration due to its closed-cell structure. It can also be used for gap filling. | Water infiltration or leakage may occur when the adhesive deteriorates within 1–3 years. | Water infiltration or leakage may occur when the adhesive deteriorates within 1–3 years, and moisture may reduce the insulation’s performance. | Water infiltration or leakage may occur when the adhesive deteriorates within 1–3 years. |
| Rust Prevention | PU/PIR foam helps protect the roofing sheet from exposure to air and moisture. | Rust may occur if the adhesive deteriorates and the insulation separates from the roofing sheet. | Rust may occur if the adhesive deteriorates and the insulation separates from the roofing sheet. | Rust may occur if the adhesive deteriorates and the insulation separates from the roofing sheet. |
| Service Life |
Long-lasting and durable, with a service life of over 30 years.
(Based on surveys conducted in European countries.) |
Service life depends on the quality of the bond between the insulation and roofing sheet, as well as operating conditions. | Service life depends on the quality of the bond between the insulation and roofing sheet, as well as operating conditions. | Service life depends on the quality of the bond between the insulation and roofing sheet, as well as operating conditions. |
