How do Extira panels perform in laboratory testing?
CMI conducted field tests for rot and termite resistance on Extira panels and southern yellow pine. The testing was performed by Louisiana State University in the swamps of southern Louisiana. Each test was run for 3 years, with observations recorded every six months. Termite Resistance Test standard: AWPA E7 – Standard Method of Evaluating Wood Preservatives by Field Tests with Stakes. Test dates: June 2003 through June 2006. Test variables: Extira Panels 3/4″ and 1″. Southern Yellow Pine 3/4″ and 1″. Rating scale: The rating scale is from 0 to 10, where a score of 0 represents complete failure and 10.0 represents no termite activity. Test results: After 18 months of exposure, Extira panels showed less than 25% termite activity on both 3/4″ and 1″ samples. Over the same evaluation period, the southern yellow pine was completely destroyed. The full test data for both 12-month and 18-month observations are recorded below. TERMITE TEST: Rot Resistance Test standard: AWPA E16 – Field Test
