Which product has the higher temperature rating?

• A. Styrofoam Insulation
• B. Styrospan
• C. Styrofoam
• D. Styroform

Answer: (B)

Temperature rating is about how hot a material can be and still perform without degrading or losing its insulating properties. Styrospan is formulated for higher thermal stability, with a cell structure and additives that withstand higher temperatures better than standard polystyrene foams. That makes it the better choice when you expect exposure to hotter conditions. The other products are generally used for more typical insulation applications and have lower maximum service temperatures, where they might soften or lose effectiveness if heated too much. Always check the product data sheet for the exact rating, since formulations and grades can vary.
