Unlike regular foam board whose surface has a pH rating of 6.5, this sheet has a pH rating in the 7.3 to 8.5 range. Each board has been buffered with an alkaline substance to maintain the pH level for years. Available in white and antique white.

Sorry, foam board is only available for in-store pickup and local delivery to the Los Angeles area (additional charges apply for delivery).
