PUF Panel Thickness Guide for Industrial Buildings
Choosing the correct PUF panel thickness is critical for insulation performance, compliance, and cost optimization. This guide helps you select the right thickness based on application.
Introduction
Choosing the correct PUF panel thickness is critical for insulation performance, regulatory compliance, and cost optimization. This comprehensive guide helps you select the right thickness based on your specific application and requirements.
Common PUF Panel Thickness Options
PHOENIXX manufactures PUF panels in the following standard thicknesses:
| Thickness | Best Applications | R-Value (m²K/W) |
|---|---|---|
| 30-40 mm | Office partitions, light insulation, interior walls | 1.25-1.67 |
| 50-60 mm | Warehouses, industrial sheds, commercial buildings | 2.08-2.50 |
| 80-100 mm | Cold storage (+2°C to +8°C), temperature-controlled areas | 3.33-4.17 |
| 120-150 mm | Freezers (-18°C to -25°C), deep cold rooms | 5.00-6.25 |
How to Choose the Right Thickness
Consider these factors when selecting PUF panel thickness:
1. Temperature Differential
The greater the difference between inside and outside temperatures, the thicker the panel needed:
- Small difference (5-10°C): 40-50mm panels
- Moderate difference (15-25°C): 60-80mm panels
- Large difference (30-50°C): 100-150mm panels
2. Climate Conditions
- Hot climates (Gujarat, Rajasthan): +10-20mm additional thickness recommended
- Moderate climates: Standard thickness sufficient
- High humidity areas: Consider vapor barriers
3. Energy Efficiency Goals
- Basic compliance: Minimum recommended thickness
- Energy optimization: +20-30% thicker panels
- Green building certification: Maximum practical thickness
4. Regulatory Requirements
- Pharmaceutical facilities: CGMP-specified insulation values
- Food processing: FSSAI/HACCP temperature requirements
- Cold storage: WDRA/NHB specifications
Application-Specific Recommendations
Warehouses & Industrial Sheds
- Roof panels: 50-60mm PUF
- Wall panels: 40-50mm PUF
- Key benefit: Reduced cooling load, worker comfort
Cold Storage (Chilled: +2°C to +8°C)
- Roof panels: 100mm PUF or PIR
- Wall panels: 80-100mm PUF or PIR
- Floor insulation: 100mm with vapor barrier
Freezer Rooms (-18°C to -25°C)
- Roof panels: 150mm PIR panels
- Wall panels: 120-150mm PIR
- Floor insulation: 150mm with heating cables
Deep Freeze (-35°C to -40°C)
- All surfaces: 175-200mm PIR panels
- Critical: Professional vapor barrier installation
Cost vs Performance Analysis
While thicker panels cost more upfront, they offer higher energy savings and faster ROI in temperature-critical applications:
| Scenario | Additional Cost | Annual Savings | Payback |
|---|---|---|---|
| 50mm → 80mm (Warehouse) | +15% | 10-15% energy | 3-4 years |
| 80mm → 100mm (Cold Storage) | +20% | 15-20% energy | 2-3 years |
| 100mm → 150mm (Freezer) | +25% | 20-25% energy | 2-3 years |

Frequently Asked Questions
What PUF panel thickness is best for a warehouse?
For standard warehouses in India, 50-60mm PUF panels for roofing and 40-50mm for walls provide good insulation and cost efficiency. In hotter regions, consider 60-80mm for better energy savings.
What thickness is required for cold storage?
Cold storage (+2°C to +8°C) typically requires 80-100mm PUF/PIR panels. Freezer rooms (-18°C to -25°C) need 120-150mm panels for optimal efficiency and compliance.
Does thicker always mean better?
Thicker panels provide better insulation but cost more. The optimal thickness balances thermal requirements, budget, and payback period. PHOENIXX engineers can help calculate the most cost-effective option for your specific application.
What is the price difference between thicknesses?
Generally, each 20mm increase in thickness adds approximately 15-20% to the panel cost. However, thicker panels also provide proportionally better insulation and energy savings.
