Introduction: Making the Right Choice in Insulation
Thermocol sheets have become an essential part of building insulation across Pakistan. Whether you’re constructing a new house, renovating your rooftop, or insulating an industrial unit, selecting the correct thickness of thermocol sheet — particularly between 1 inch and 2 inch sheets — can make a significant difference in energy efficiency, cost-effectiveness, and overall comfort.
In this detailed guide, we’ll explore the difference between 1 inch and 2 inch thermocol sheets, compare performance, pricing, and ideal applications, and help you decide which option is best suited for your specific needs in Pakistan’s climate.
What Is a Thermocol Sheet? (EPS Explained)
Thermocol, technically known as Expanded Polystyrene (EPS), is a white, rigid, and lightweight foam material made from polystyrene. It is commonly used in:
Roof insulation
Wall and ceiling insulation
False ceiling installations
Industrial packaging and cushioning
Core Benefits of Thermocol Sheets:
High thermal resistance
Excellent moisture resistance
Lightweight and easy to handle
Budget-friendly compared to other insulators
Available in various thicknesses and sheet sizes
1 Inch vs 2 Inch Thermocol Sheet: Side-by-Side Comparison
| Feature | 1 Inch Thermocol Sheet | 2 Inch Thermocol Sheet |
|---|---|---|
| Thickness | 25 mm | 50 mm |
| Thermal Insulation | Moderate | High |
| Weight | Light | Heavier |
| Ideal Usage | False ceilings, packaging | Roof insulation, exterior walls |
| Cost | Lower | Higher |
| Suitable Regions | Moderate climates (e.g., Lahore) | Hot zones (e.g., Karachi, Multan) |
When to Use a 1 Inch Thermocol Sheet
1 inch thermocol sheets are best for light-duty insulation projects and budget-friendly installations. They provide decent thermal insulation in areas with moderate temperature fluctuations.
Best Use Cases for 1 Inch Sheets:
False ceiling design (gypsum + thermocol combination)
Wall lining or inner partitions
Low-budget insulation for small homes or rooms
Lightweight packaging for fragile goods
If you’re in cities like Islamabad, Lahore, or Faisalabad, where the heat is manageable, a 1 inch sheet can perform adequately.
When to Choose a 2 Inch Thermocol Sheet
For long-term insulation performance and maximum heat resistance, a 2 inch thermocol sheet is the top choice. Its double thickness offers superior thermal performance, making it suitable for extreme heat zones and industrial projects.
Best Use Cases for 2 Inch Sheets:
Roof heat proofing in cities like Karachi, Multan, Bahawalpur
Insulating commercial and industrial buildings
Homes with exposed rooftops or older construction
Reducing air-conditioning bills in summer months
Temperature control for storage areas or cold rooms
Thermocol Sheet Prices in Pakistan (2025 Updated)
As of 2025, here are the average market prices for thermocol sheets in Pakistan. Note that prices can vary depending on city, supplier, and brand.
| Sheet Size | 1 Inch Price (PKR) | 2 Inch Price (PKR) |
|---|---|---|
| 4 x 4 feet | 300 – 350 | 550 – 650 |
| 4 x 8 feet | 600 – 700 | 1000 – 1200 |
Pro Tip: Bulk purchases and direct-from-manufacturer deals can help you save up to 15–20% on large orders.
Installation Tips for Maximum Performance
To get the most out of your thermocol sheets, especially in Pakistan’s high heat environments, proper installation is key.
Pro Installation Tips:
Always seal all joints using foam adhesive, aluminum tape, or joint filler.
For roofs, add a protective layer of aluminum foil or gypsum board to reflect UV rays.
Avoid exposure to open flames or extreme chemicals, as EPS is flammable.
Ensure the sheets are installed tightly without air gaps to prevent heat transfer.
Thermocol Sheets vs Other Insulation Materials
If you’re comparing thermocol sheets with glass wool, polyurethane foam, or rockwool, remember that EPS is:
More affordable
Easier to install
Lightweight but less dense
Reusable for temporary installations
However, for high-performance insulation, thicker EPS (like 2 inch) competes well with polyurethane in terms of thermal resistance (R-value).
