Product type
EPS insulation sheets, or expanded polystyrene insulation, are lightweight, rigid panels made from expanded polystyrene beads. They are produced through a process of heating and expanding the beads, resulting in a material that provides excellent thermal insulation properties. EPS sheets are commonly used in construction for insulating roofs, walls, and floors, contributing to energy efficiency and temperature regulation within buildings.
| Thermal conductivity | 0.030 to 0.040 W/mK |
| Density | 10 to 35 kg/m³ |
| Thickness | 20 to 300 mm |
| Compressive strength | 80 to 300 kPa |
| Fire rating | Class E or Class B2 (depending on treatment) |
When selecting EPS insulation sheets, consider the required thermal resistance and the specific application to ensure optimal performance. Specify the desired thickness, density, and any fire rating requirements. It's also important to request information on certifications and compliance with local building codes. Quantities should be based on the total area to be insulated, allowing for waste and cuts during installation.
