Glued-in-rods represent a particular class of adhesively bonded joints in which load is transmitted from timber elements by means of rods through a layer of adhesive. As such they share with all adhesively bonded connections the issues that are associated to adhesives. This study will shed new light on issues of particular relevancy for practitioners: adhesives do only cure at specific temperature ranges, which are frequently not met in cold climates thus constituting an obstacle towards their use; and, commonly used adhesives, often cold curing 2C epoxies or polyurethanes, only cure relatively slowly, which makes glued-in rods tributary to (costly) temporarily fixing systems.
