How Much Is a Sheet Of Polystyrene?

The cost of a polystyrene sheet in South Africa depends on several important factors, including the thickness, density, and type of sheet. Expanded polystyrene (EPS) is the most common choice and generally the most affordable. Its versatility and ease of use make it a popular material for everything from insulation to creative projects. Prices vary between suppliers and depending on the scale of your project, but EPS sheets are widely recognized for being budget-friendly.

Key Factors That Impact the Cost

The price of a polystyrene sheet is usually influenced by its thickness and density. Thicker sheets used for structural or underfloor applications tend to be more expensive because they offer better strength and insulation performance. Density also plays a role—higher density sheets are stronger and more durable. In addition, custom cutting, project size, and delivery requirements can all affect the final cost you pay.

A Smart and Cost-Effective Choice

Even though polystyrene sheet prices can vary, this material remains a great value for both homeowners and commercial builders. It’s lightweight, easy to install, and can help reduce heating and cooling costs by improving your building’s thermal performance. Plus, it’s available nationwide and comes in a range of thicknesses and densities to suit every project.
