Testing Results
Acoustic Performance Test
This test confirms that Wynstellar internal doors provide reliable acoustic insulation between rooms. Laboratory testing shows an average 23 dB sound reduction, improving privacy and comfort in residential, hospitality, and workplace interiors. The results also verify stable bonding between veneer and core, ensuring consistent acoustic performance over time.
Structural Bending Strength Test
This test verifies the structural strength and stiffness of Woodlam glulam beams under EN 408 and EN 14080 methods. Results confirm predictable load-bearing capacity and deflection control, giving engineers confidence for long-span, seismic, and architectural applications.
Delamination Resistance Test
This test confirms long-term adhesive durability under moisture exposure. Delamination values are well below EN 14080 limits, demonstrating strong glue-line integrity and dimensional stability. The result guarantees reduced risk of bond failure in humid tropical environments.
Fire Resistance Test
Fire testing to SNI 1741:2008 / ISO 834 confirms a Fire Resistance Rating (FRR) of 60 minutes. The panel maintained structural integrity with predictable charring behaviour and intact adhesive lines, meeting public and commercial building code requirements for fire safety.
Structural Glue & Finger-Joint Strength Test
This test verifies the structural reliability of finger-jointed Jabon lamellas for glulam and CLT use under Eurocode 5. Results show failures occur in the wood rather than the glue line, confirming that the adhesive system meets required structural strength standards.
Wood Durability & Termite Resistance Test
This test demonstrates that treated Jabon achieves Class I durability under JIS K 1571 standards. The treatment provides proven resistance against aggressive tropical termites, ensuring long-term performance and reduced maintenance risk for interior and light exterior applications.
Legal Certifications
Woodlam’s SVLK certification confirms that all timber is legally sourced, traceable, and compliant with Indonesia’s national timber legality system. This guarantees regulatory compliance for domestic use and export, reducing procurement risk and supporting responsible forestry.
Woodlam’s TKDN certification verifies a high domestic content level across key products, including Glulam Jabon and V-Panel Meranti. With TKDN values of up to 97.24%, it confirms eligibility for government and institutional projects while supporting Indonesia’s local manufacturing supply chain.
