Pre-insulated ducting price per m2 is the most common question when procurement teams begin preparing cleanroom project budgets. Price ranges in the market vary widely, from IDR 450,000 to IDR 1,200,000 per square meter depending on technical specifications, panel thickness, and ducting design complexity.
This article discusses pricing details, cost factors, and a checklist you need to consider before ordering pre-insulated ducting for your cleanroom HVAC system.

Products and Systems Offered
Pre-insulated ducting is an air distribution system using sandwich panels with insulating core material, typically PIR (Polyisocyanurate) or PU (Polyurethane). These panels have aluminum foil or metal sheet layers on both sides that function as vapor barriers and structural support.
In Indonesia, pre-insulated ducting is available in several variants:
- PIR Ducting - B1 fire rating, thermal conductivity 0.021 W/mK, suitable for ISO 5-8 cleanroom classes
- PU Ducting - Thermal conductivity 0.020 W/mK, more economical pricing, common for commercial applications
- Phenolic Ducting - Best fire rating (A2), premium pricing, for high-risk applications
PT. Ruida Grup Indonesia provides all three material types with panel thickness ranging from 20 mm to 100 mm according to project requirements.
Key Specifications to Consider
Before asking for prices, ensure you understand the technical specifications needed. Several critical parameters include:
Panel Thickness and Density
Panel thickness affects thermal insulation capability and structural strength. For standard ISO 14644 cleanrooms, common thicknesses used are:
- 20-30 mm - For small ducting (diameter under 300 mm)
- 40-50 mm - Standard for main cleanroom ducting
- 60-100 mm - For high-capacity HVAC or outdoor exposed ducting
Fire Rating and Certifications
Fire safety standards must be met, especially for pharmaceutical industries referring to CPOB BPOM regulations. Ensure materials have:
- Fire test certificates from accredited bodies (BS 476, EN 13501)
- Food grade certification for pharmaceutical and food processing applications
- ISO 9001:2015 for manufacturer quality management
Pressure Resistance and Air Leakage
Cleanrooms require ducting systems with minimal leakage levels. Common specifications required:
- Pressure class: 500 Pa to 2500 Pa depending on system
- Air leakage: Class B or better (per SMACNA)
- Surface roughness: under 0.3 mm to minimize pressure drop
Factors Affecting Price
Pre-insulated ducting price per m2 cannot be set absolutely as it is influenced by several variables:
1. Core Insulation Material
PIR has prices 15-20% higher than PU due to better fire rating performance. Phenolic can be 30-40% more expensive than PIR. Material choice must be adjusted to regulations and project budget.
2. Ducting Design Complexity
Ducting with many fittings (elbows, reducers, tees) requires longer fabrication time and higher material waste. Simple ducting systems (straight runs) are certainly more economical than complex layouts.
3. Project Volume and Scale
Suppliers generally provide tier pricing:
- Project under 100 m2 - Retail pricing, minimum order charges apply
- Project 100-500 m2 - Project pricing with 5-10% discount
- Project over 500 m2 - Volume pricing with 15-25% discount
4. Delivery and Installation Location
Logistics costs for delivery outside Java can add 10-15% to total material prices. If using supplier installation services, labor and team travel factors also need to be considered.
Price Estimation per m2 for 2026
Based on market surveys and project data handled by PT. Ruida Grup Indonesia, here are pre-insulated ducting price estimates per m2:
| Material | Thickness | Price per m2 (IDR) |
|---|---|---|
| PU Standard | 40 mm | 450,000 - 550,000 |
| PU Premium | 50 mm | 550,000 - 650,000 |
| PIR Standard | 40 mm | 600,000 - 750,000 |
| PIR Premium | 50 mm | 750,000 - 900,000 |
| Phenolic | 40 mm | 950,000 - 1,200,000 |
Note: Prices above are for material supply only. Installation costs are generally added at 30-50% of material price depending on complexity.
Core Options, Thickness, and Applications
Material and thickness selection must be based on specific applications:
Pharmaceutical and Laboratory Industries
Cleanrooms for drug production require materials with food grade certification and high sanitation capability. PIR 50 mm is the standard choice because of the balance between thermal performance, fire safety, and price.
Electronics and Semiconductor Industries
ISO 5-6 class cleanrooms require ducting with high surface smoothness and minimal off-gassing. Phenolic or premium PIR with special aluminum foil layers are recommended.
Food Processing and Cold Storage
Low temperature applications require extra insulation. Thickness of 60-80 mm with PU or PIR material can maintain minimal thermal bridging and high energy efficiency.
Checklist Before Ordering
To avoid ordering mistakes and budget overruns, ensure you have checked the following points:
- Confirm technical specifications with project HVAC consultant
- Verify fire and food grade certificates from supplier
- Request detailed shop drawings and bill of quantities
- Ask about production lead time and delivery schedule
- Clarify installation scope (whether included or separate)
- Ensure material and workmanship warranty is stated in contract
- Check supplier previous project references
Frequently Asked Questions Before Purchase
Is the price inclusive of accessories and fittings?
Price per m2 is generally only for straight ducting. Accessories such as elbows, reducers, dampers, and flanges are charged separately or calculated in a special BOQ. Ensure this clarification when requesting quotation.
What is the lead time for pre-insulated ducting production?
Lead time varies 2-6 weeks depending on volume and complexity. Large projects with custom profiles may require longer time. Always confirm timeline when placing orders.
Can I request custom sizes and profiles?
Yes, pre-insulated ducting can be fabricated according to project shop drawings. However, non-standard custom sizes may add 10-20% to costs due to machine setup and material waste.
How to ensure installation quality?
Choose a supplier that provides certified installation services. Verify the install team experience and request quality inspection schedules at project milestones. Pressure testing and smoke testing must be conducted before handover.
FAQ About Pre-Insulated Ducting
What is the difference between PIR and PU for ducting?
PIR has a better B1 fire rating than PU, making it safer for pharmaceutical and electronics applications. PU has slightly lower thermal conductivity and more economical pricing for standard commercial applications.
How long is the warranty for pre-insulated ducting?
Material warranty is generally 10 years for core insulation and 5 years for workmanship. Ensure the warranty is written in your purchase contract.
Can pre-insulated ducting be used outdoors?
Yes, with 60-100 mm thickness and UV protection coating on the aluminum layer. However, for extreme outdoor applications, phenolic or additional cladding protection is recommended.
