What is the temperature rating for Styrospan (polystyrene)?

Explanation:
Polystyrene foam insulation has a maximum continuous operating temperature to keep its structure and insulating value intact. Styrospan is rated for a continuous service temperature of 175°F. Staying at or below this temperature maintains its cellular integrity and performance; going higher can soften or deform the foam, reducing R-value and potentially compromising the board or its attachments. So, 175°F is the correct rating. Exceeding it (like 180°F) risks damage, while lower ratings (such as 165°F) would be too conservative for this product, and a range doesn’t reflect the published continuous rating.
