Eco Friendly Adhesives and Sealants Gain Momentum in Green Building Certifications

Formaldehyde-free wood glues made from soy protein and lignin derivatives have achieved performance parity with synthetic resins in load-bearing applications. Meanwhile, silicone sealants derived from rice husk ash offer excellent adhesion to glass and aluminum while sequestering carbon. Major certification bodies have updated their material databases, making it easier for specifiers to select compliant products. A survey of contractors shows that 68% now prioritize low-emission adhesives even when not required by code.
