FIRENWOOD will fill knowledge gaps regarding fire safe use of engineered wood systems, with focus on structural joints and adhesives in cross-laminated timber (CLT), glued-laminated timber (GLT) and wood-based I-joists, and develop validated and relevant fire design models for these systems as well as classification methods for adhesives. A key point is to investigate the behavior of adhesives used in structural applications, as many of these innovative systems utilize different adhesives.
Testing with 11 selected adhesives will be performed in different labs and at different scale including cone calorimeter tests, fire tests and tests at elevated temperatures. Appropriate test methodology will be proposed to evaluate adhesive behavior. Fire design models for eng. wood products will be improved taking into account the influence of adhesive behavior.
