How Pre-insulated Duct Panel For Air Conditioning Works
The pre-insulated duct panel features a PIR closed-cell foam core (thermal conductivity ≤ 0.022W/m·K), combined with a double-sided moisture-resistant aluminum foil composite structure. Through a closed-cell foaming process, it creates an airtight thermal insulation layer that blocks heat and cold exchange³. The tongue-and-groove flange design enables seamless assembly, reducing thermal bridge effects at joints and ensuring stable overall thermal performance of the system.

When to Use Pre-insulated Duct Panel For Air Conditioning
New Commercial Buildings：Meets the needs of modern central air conditioning systems for energy efficiency and space intensification.
Retrofitting of Old Ducts：Adapts to energy-saving upgrades of existing buildings without large-scale structural modifications.
High-Humidity Environments：The aluminum foil layer resists mildew and corrosion, suitable for environments with humidity >85% (e.g., food processing workshops, swimming pools).
Strict Fire Control Zones：With B1-level flame retardancy, it complies with safety codes for public spaces such as shopping malls and hospitals.

Why Choose Pre-insulated Duct Panel For Air Conditioning
| Characteristics | Descriptions |
| Low thermal conductivity, excellent thermal insulation performance | Low thermal conductivity (0.018 - 0.024 W/(m.K)), with thermal insulation effect far superior to EPS. |
| Moisture - proof and waterproof | Closed - cell rate > 90%, does not absorb water, and does not affect the thermal insulation effect. |
| Flame - retardant and high - temperature resistant | Self - extinguishing after adding flame retardant, softening point > 250℃, and a carbon layer is formed during combustion to prevent flame spread. |
| Stable structure, strong durability | Closed - cell structure, resistant to freeze - thaw, good sound absorption, and service life exceeds 30 years. |
| Resistant to deformation, not easy to crack | The plate is sturdy and durable, maintaining a stable appearance. |
| Space - saving | Superior thermal insulation performance allows for achieving the same thermal insulation effect with a thinner thickness, improving the utilization rate of indoor space. |
| Environmentally friendly and energy - saving | Foamed without fluorine, free of harmful substances, meeting environmental protection requirements. |
| High cost - performance ratio | Although the unit price is relatively high, it can significantly reduce air - conditioning energy consumption, being more economical in the long run. |
