  I'd be very surprised if animal glue was used in any engineered wood. Even in fine woodworking it's a niche product; it's expensive and generally doesn't work as well as other glues.

    On the other hand, it is reversible. https://woodworkingparts.wordpress.com/2010/08/17/hide-glue-and-the-titebond-advantage https://woodworkingparts.wordpress.com/2010/08/17/hide-glue-... "The significant disadvantages of hide glue – its thermal limitations, short open time, poor gap filling capability and vulnerability to micro-organisms – are offset by several advantages. Hide glue joints are reversible and repairable. Recently glued joints will release easily with the application of heat and steam. Hide glue sticks to itself, so the repairer can apply new hide glue to the joint and reclamp it. In contrast, PVA glues do not adhere to themselves once they are cured, so a successful repair requires removal of the old glue first – which usually requires removing some of the material being glued."
