Buy low price Graphite EPS Expanded Polystyrene Insulation 20-30 degree temperature with Wedge Insulation Boards for Roof Insulation. Expanded Polystyrene Graphite Sheets (EPS-G or Grey EPS) are advanced insulation materials made by infusing regular white EPS (Expanded Polystyrene) with graphite particles. These particles significantly enhance the thermal insulation performance of the material.
What Are EPS Graphite Sheets?
Base Material: Polystyrene beads
Additive: Graphite particles
Color: Typically grey or silver (due to the graphite)
Form: Rigid foam sheets
Key Features
Improved Thermal Performance:
Graphite reflects radiant heat, reducing thermal conductivity.
Up to 20–25% better insulation compared to standard white EPS.
Lightweight & Durable:
Easy to handle and install.
Resistant to moisture, aging, and decay.
Eco-Friendly:
Recyclable.
Reduced energy consumption for heating/cooling when used in buildings.
Cost-Effective:
More affordable than some other insulation materials like PIR or XPS.
Common Applications
Building Insulation (External/Internal Walls, Roofs, Floors)
Cold Storage Rooms
Prefabricated Houses
Underfloor Heating Systems
