Table 6. Duncan’s multi-range tests for wood species and wood product

Parameter	Wood species			Wood product
Parameter	Manii	Mangium	Rubber-wood	Polystyrene glulam	Control glulam	Solid wood
Density (g/cm³)	0.49^a	0.67^b	0.73^c	0.68^q	0.61^p	0.60^p
Moisture content (%)	13.80^a	14.20^a	14.21^a	13.91^p	14.00^p	14.29^p
Weight loss (%)	51.20^a	4.27^c	26.09^b	23.05^q	27.55^pq	31.00^p
Protection level	4.94^a	8.94^c	6.72^b	7.50^q	7.00^q	6.11^p

The same letter following the values for each parameter, wood species, and wood product indicates no significant difference.
