Sandwich Panel in Pakistan – Complete Industrial Guide (2026)

Introduction

Pakistan ki construction industry mein ab sirf traditional brick aur concrete systems use nahi ho rahe. Modern industrial construction rapidly energy-efficient aur fast-building systems ki taraf shift ho rahi hai.

In modern solutions mein sab se important material Sandwich Panels hain.

Ye panels specially PEB buildings, cold storages, warehouses, prefab houses aur industrial sheds mein use hotay hain.

Iski demand Pakistan mein is liye barh rahi hai kyun ke:

• Heat control strong hota hai
• Construction fast hoti hai
• Energy cost save hoti hai
• Maintenance low hota hai

🏭 What is a Sandwich Panel?

Sandwich panel ek composite building material hota hai jo 3 layers par based hota hai:

• Outer metal sheet (GI / PPGI)
• Core insulation material (PU, EPS, Rockwool)
• Inner metal sheet

Ye structure bilkul sandwich ki tarah hota hai is liye isay “sandwich panel” kehte hain.

🧊 Structure of Sandwich Panel

1. Outer Sheet

Galvanized steel ya color-coated sheet hoti hai jo weather protection deti hai.

---

2. Insulation Core

Main heat barrier hota hai:

• Polyurethane (PU)
• Expanded Polystyrene (EPS)
• Rockwool (fire resistant)

---

3. Inner Sheet

Interior protection aur finishing provide karta hai.
