The adhesive that bonds the door skin to the core is not a minor detail — it is a structural element. A fire door that delaminates at 400°C is no longer a fire door. It is a liability. This article explains the standards and specifications that govern fire door assembly glue. We will walk through the performance requirements, the testing regimes, and the practical steps for selecting and applying a fire-retardant adhesive that passes certification. If you manufacture fire doors, specify them, or assemble them, this guide is for you.
