Import Tips & Compliance
• Include acoustic performance test data if marketed for sound reduction in multi-family construction
• Certify flatness tolerances for underlayment use to support building construction classification
• Avoid declaring as 'flooring' to prevent shift to 4412; specify as subfloor component only
