Insulated sandwich panels provide superior thermal efficiency for modern construction. They excel as sandwich panel walls in industrial and cold storage applications.
What Are Insulated Sandwich Panels?
Insulated sandwich panels consist of two metal sheets bonded to a core like polyurethane (PU), polyisocyanurate (PIR), or mineral wool. This design delivers excellent thermal insulation with λ-values from 0.024 W/m·K for PU to 0.05 W/m·K for wool.
These panels minimize thermal bridges at joints, supporting spans up to 11m for walls. Thickness ranges 40-200mm, density 10-35 kg/m², making them lightweight yet strong.
Sandwich panel walls use these for facades, offering soundproofing, fire resistance (PIR superior), and quick assembly via screws.
Benefits of Sandwich Panel Walls
Sandwich panel walls ensure energy savings by stabilizing temperatures, cutting heating/cooling costs. They resist water, fire, and corrosion, ideal for harsh environments.
Installation is fast—screw to structure in hours—reducing labor by 50% vs. traditional walls. Lightweight nature eases transport and handling.
For cold storage, they maintain -20°C with minimal energy loss, boosting efficiency.
Types of Insulated Sandwich Panels
Panels vary by core:
- PU/PIR: Best insulation, fire-safe (PIR).
- EPS/Rockwool: Cost-effective, sound-absorbing.
- Glasswool: High fire rating.
External sheets are galvanized steel (0.3-0.7mm), coated for durability.
| Core Type | Thermal Conductivity (W/m·K) | Fire Rating | Common Use | Approx. Weight (kg/m²) |
|---|---|---|---|---|
| PU | 0.024 | B2 | Cold Rooms | 10-15 |
| PIR | 0.022 | B1 | Walls/Roofs | 12-18 |
| Mineral Wool | 0.035-0.05 | A1 | Fire Walls | 20-35 |
| EPS | 0.030-0.040 | B3 | Budget Builds | 8-12 |
Applications in Construction
Insulated sandwich panels suit industrial sheds, warehouses, pharma cleanrooms, and food processing. As sandwich panel walls, they clad commercial buildings aesthetically.
In cold storage, they prevent frost buildup. Hospitals use them for hygiene partitions.

Insulated Sandwich Panel Price Factors
Insulated sandwich panel price depends on thickness, core, sheet gauge, and quantity. In India, expect ₹1100-1600/sq m for 50mm PU panels.
Bulk orders lower costs; custom colors add 10-15%. Installation ~₹100-200/sq m extra.
| Thickness (mm) | Core | Sheet (mm) | Price Range (₹/sq m) | Ideal For |
|---|---|---|---|---|
| 40 | PU | 0.5 | 1100-1300 | Roofs |
| 50 | PIR | 0.5 | 1200-1400 | Walls |
| 80 | Wool | 0.6 | 1400-1600 | Cold Storage |
| 100 | EPS | 0.4 | 900-1200 | Budget |
Installation Guide for Sandwich Panel Walls
- Prepare frame with purlins 3-5m apart.
- Align panels, seal joints with PU sealant.
- Fix with concealed screws for seamless look.
Safety: Use harnesses; ensure even load. Pro install recommended for large projects.
Maintenance and Durability
Clean with mild soap; inspect seals yearly. Panels last 20-30 years, resisting UV and chemicals.
