1. There is a request for 1” board on the sidewall for this project. The sidewalls require the use of 2” of board and 2” wool for safety reasons. We believe that this request may be a mistake. The requested boards (1”) are used on the baffles with 2” wool. If they changed the sidewall requirement to 1” board it will not offer the same level of anti-ricochet and anti-splatter protection as well as noise reduction per either the ETL or the UFC. Please verify that the requirement is 1” or 2” board and please verify the board count. 2. Are there any specific warranty requirements?
