Guide to Polystyrene Sheet Thickness and Density Explained
Choosing the right thickness and density of polystyrene sheets is key to maximizing their performance in insulation and construction. Thickness mainly affects thermal resistance, while density influences strength and durability. Understanding these factors helps South African builders and homeowners pick the best product for their needs.
What Thickness Means for Insulation
Thickness determines how well polystyrene sheets resist heat transfer. Thicker sheets provide better thermal insulation, helping keep indoor spaces comfortable in varying South African climates. Common thicknesses range from 20mm to 600mm or more, depending on the application and required R-value.
How Density Affects Strength and Use
Density is the weight of the material per cubic meter and relates to how compact the foam is. Lower density sheets are lighter and easier to handle, ideal for ceilings and light insulation. Higher density sheets offer greater compressive strength, perfect for floors, void formers, and load-bearing applications.
Balancing Thickness and Density
Selecting the right combination of thickness and density is vital. For example, a thicker low-density sheet may offer similar insulation to a thinner high-density one but with less structural strength. Your choice depends on whether insulation or load-bearing capacity is the priority for your project.
