Good For The Environment

	No old growth wood is used in the manufacture of Extira panels. They are made from leftover wood that is of no commercial timber value and is the byproduct of other operations. This wood is also detrimental to the over all vitality of the forest. CMI uses 100% northern hardwoods. All wood comes from an area within a 200 mile radius of the Towanda, Pennsylvania production facility.
	Extira panels have no added urea formaldehyde. This is certified by Scientific Certification Systems, certificate number SCS-MC-01802.
	Due to their physical composition, Extira panels are not subject to the California Air Resources Board's (CARB) Airborne Toxic Control Measure 93120 (ATCM). This measure enforces limits on formaldehyde emissions. If they were subject to the ATCM rule, Extira panels would meet the specification for the designation "ultra low formaldehyde emitter."
	Through repeated testing by the Composite Panel Association (CPA), a third party certifier for the ATCM rule, Extira panels have demonstrated formaldehyde emissions equivalent to background levels found in the environment.
	Extira panels contribute to industry programs such as LEED® 2009 for Commercial Interiors, LEED 2009 for New Construction and Major Renovations, LEED for Homes and NAHB - National Green Building Standard™

Extira Panels Perform Better than MDF

How do Extira panels compare to typical MDF?

Extira Panels are Stronger and Perform Longer

Testing Insures Quality
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 for Evaluation of Wood Preservatives to be used Out of Ground Contact: Horizontal Lap-Joint Method.

Test dates:
May 2003 through June 2006.

Test variables:
Extira Panels 3/4" and 1".
Southern Yellow Pine 3/4" and 1".

Rating scale:
The test is rated on a 0-5 scale. A score of 0 indicates no evidence of rot and a score of 5 represents a total failure (eg. test sample was destroyed by rot). A score of 1.0 indicates that the sample shows trace attacks of rot, limited to superficial damage. Observations were recorded at the joints and laps (outside). Lap measurements are reported in this document.

Test results:
After both 18 months and 3 years of exposure, Extira panels scored a 1.0 for both 4/4 and 5/4. A full breakdown of the observations follows.

After 3 years of exposure, the southern yellow pine showed total failure, scoring 5.0 for both thicknesses tested. After 18 months, the southern yellow pine received a rating of 3.1. A rating of 3.0 indicates moderate attack with softening of wood evident, consistent with rot decay in areas greater than 0.5".

ROT TEST:

Thickness Swell
As measured by ASTM D1037-99, Extira panels showed thickness swell approximately 40% less than MR 50 MDF. Moisture Resistant Grade 50 MDF has a maximum thickness swell of 5%.

Accelerated Aging Test
As measured by ASTM D1037-99, Extira panels retained 90% of its original strength after the 6-cycle accelerated aging test. The accelerated aging test is a means of testing the durability of a product when it is submitted to seasonal changes. To do this, the product undergoes cycles of freezing, thawing, soaking, and heating to mimic conditions in areas of seasonal change in terms of humidity, temperature and moisture.
