TECHNICAL INFORMATION – PHYSICAL PROPERTIES
Foam Technologies EPS Block is manufactured to AS 1366, Part 3-1992, Rigid Cellular Plastic Sheets for Thermal Insulation, Rigid Cellular Polystyrene, in six classes. The standard designates a colour to identify each of the six classes:
Class L: Blue Class M: Black
Class SL: Yellow Class H: Green
Class S: Brown Class VH: Red
The standard specifies the minimum physical property limits for each of the six classes (See
Table 1) and methods for determination of compliance
The thermal conductivity of expanded polystyrene sheet grades is shown in the reference below.
|SL Grade||k = 0.041 W/mk*|
|S Grade||k = 0.0397 W/mk*|
|M Grade||k = 0.0383 W/mk*|
|H Grade||k = 0.0368 W/mk*|
|VH Grade||k = 0.0352 W/mk*|
|* k value @ reference temperature 25°C|
Nominal R-values (m²K/W) – excluding surface resistance
|EPS sheet thickness||SLGrade||SGrade||MGrade||HGrade|
