Do Splits Along Glue Lines Mean Delamination Has Occurred?
Actual delamination is a failure in the laminating process. While an opening along a glue line may be indicative of delamination, there are other more common causes. Typical checking that occurs in large section timber in response to moisture variation will most naturally occur in Glulam along a glue line where the natural continuation of the timber fibres is interrupted. This is often mistaken for delamination.
