Polystyrene testing in the field of construction involves the evaluation of properties and performance of polystyrene-based materials, commonly used for insulation purposes. Polystyrene, available in two main forms – Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS), is widely utilized for its excellent thermal resistance, low moisture absorption, and lightweight properties. Therefore, ensuring its quality is crucial for the efficacy and safety of construction projects.

The primary purpose of polystyrene testing is to ensure that the material complies with the necessary specifications and standards. It includes the assessment of various characteristics such as compressive strength, dimensional stability, thermal conductivity, water absorption, and flammability. These attributes directly impact the performance of polystyrene as an insulator, and they influence the energy efficiency, safety, and durability of the buildings where it is used.

Polystyrene testing offers several benefits. Firstly, it confirms the quality of the polystyrene used in a construction project, promoting safer and more energy-efficient buildings. Secondly, it assists in determining the suitability of different types and grades of polystyrene for specific applications, optimizing their performance and lifespan. Lastly, it contributes to cost savings by reducing the risk of insulation failure that could lead to costly energy losses or the need for replacement.

Polystyrene testing should ideally be conducted during its manufacturing process, upon its arrival at the construction site, and also during the installation process. This ensures the material maintains its quality throughout the construction project.

Below is the list of the most common cement tests that we undertake for our clients. All our        tests are undertaken in accordance with either the British Standard of ASTM:

 

  1. Compressive Strength Test: Measures the maximum compressive force that the polystyrene can withstand without deforming.
  2. Dimensional Stability Test: Evaluates the ability of the material to maintain its dimensions under varying temperature and humidity conditions.
  3. Thermal Conductivity Test: Assesses the material’s ability to conduct heat, which affects its insulating properties.
  4. Water Absorption Test: Measures the amount of water absorbed by the material, which can affect its thermal resistance and durability.
  5. Flammability Test: Determines the material’s response to fire, including its ignitability, heat release, and smoke production.
  6. Flexural Strength Test: Assesses the material’s ability to resist deformation under load.
  7. Density Test: Measures the mass of the material per unit volume, affecting its strength and thermal performance.
  8. Surface Burning Characteristics Test: Evaluates the material’s flame spread and smoke-developed indexes when exposed to fire.
  9. Tensile Strength Test: Determines the maximum tensile stress that the material can withstand before failure.
  10. Ageing Resistance Test: Assesses the material’s ability to maintain its properties over time when exposed to various environmental factors.
