Bead method polystyrene foam insulation board SK foam

There is no need to worry about using the end material vertically or horizontally.

The strength of SK foam (compressive strength, bending strength) generally depends on density (expansion ratio), which determines the corresponding physical properties. Since the raw beads are foamed and fused in an isotropic manner during molding, there is no directional strength. When used in formwork construction, if it is a sheet material, there is no need to worry about vertical or horizontal usage concerning the thicker ends, and it possesses moderate flexibility. Therefore, when laid in areas with significant unevenness, such as under concrete floors, it has the characteristic of being less likely to crack compared to other materials when stepped on. The tendency of strength properties includes flexibility and resilience, with high bending strength and low compressive strength. Additionally, the amount of water absorption during immersion and the hygroscopicity of water vapor are minimized, which helps suppress moisture accumulation inside the insulation material, a major factor that can lead to a decrease in thermal insulation performance, thus enabling the long-term maintenance of insulation performance.
