Expanded Polystyrene/Thermocol:
Application and other Characterstics
Expanded Polystyrene (Thermocol) offers a non hydroscopic, odorless, rigid, closed cell Expanded Polystyrene containing 98% by its volume still air entrapped in its cell and is the major reason for its excellent insulation properties. Because of its closed cell structure, it offers a remarkable resistance to unwanted heat, chill and moisture to penetrate through it and also gives a rigid, structurally strong product to withstand various kind of loads and vibrations. It does not decay or age with the time and gives permanent life long insulation without regular maintenance. Perfect, even and plain surface makes its suitable to opt it for false roofing and easy to install, carry and plastering on it.
Available in rectangular slabs and semi-spherical pipe sections in all range of sizes and thickness to suit every individual's requirement.
