GluGreen has tested the South-American hardwood species Basralocus with regard to the strength of the GluGreen® finger-joints. The medium dense hardwood is finger-jointed according to the GluGreen® Standards. Such species were often used without (kiln) drying.
The finger-jointed lot of Basralocus measured moisture contents between 18 and 35% and thus was slightly air dried.
After finger-jointing, it was decided to test the bending strength according to a Dutch Standard (NEN 7076, regarding finger-joints in wood). For many applications, the bending strength is the most important value. The test results are promising: with a minimum of 69 N/mm² and an average of 88 N/mm² it is proven again that the GluGreen® finger-joints lead to high strength values. The difference between the minimum and the average is limited and confirms the reliability of the technique.
