AB  - This study reports the bonding performance of CCA treated glued laminated timber (glulam) made
from two Malaysian tropical timber species namely bintangor (<I>Calophyllum sp.</I>) from Strength Grouping (SG)
5 and Sesenduk (<I>Endospermum sp.</I>) from SG 7. All the glulam beams were exposed to three different service
conditions namely room condition, covered condition and uncovered condition for six month period prior to
the test. The bonding properties of the beams were obtained by block shear test and delamination test
accordance to malaysian standard MS758. Results showed that the delamination for untreated glulam were
higher than the delamination of treated glulam. The wood failure percentage for all glulam in all exposure
conditions were higher than the acceptance criteria for good glue line performance as stated in MS758. This
indicates that the glulam untreated and treated with CCA have good bonding performance.
