The specimens of each wood species and wood products (solid wood, control glulam, and polystyrene glulam) were exposed to the termite in a laboratory test according to Indonesian standards. Untreated or control glulam and solid wood specimens were also prepared. The polystyrene-impregnated laminae were constructed using isocyanate glue and a cold press for three-layered glulam. After drying, the laminae were impregnated with styrene monomer, then polymerized using potassium peroxydisulfate as a catalyst and heat. Three young tropical wood species, namely manii (Maesopsis eminii), mangium (Acacia mangium), and rubber-wood (Hevea brasiliensis), were cut into laminae. The connection plates were left expressed on the exterior columns, where the rafters span from inside to out.This study aimed to enhance tropical fast-growing tree species’ resistance to subterranean termite (Coptotermes curvignathus) attacks through the manufacturing of polystyrene glued-laminated timber (glulam). Each of the glulam members were also H3 treated, which increases the durability to rot and fungal growth in both exterior weather and internal pool conditions.Įach glulam member was prefabricated with drilled holes and slots to easily insert the internal steel plate connections. The portals were coated in an exterior grade cutek oil, which allows them to become a defining exterior element running along the facade. Vicbeam provided the timber columns, beams, and purlins- which are installed between each rafter beam. The mass timber elements were designed as half portal frames, spanning over the indoor pool and extending out as a feature outside the centre. Vicbeam was approached by the builders, Decode Group, to manufacture and fabricate the structural glulam timbers.
