FOR IMMEDIATE RELEASE

Louisiana-Pacific Selects MEGTEC CLEANSWITCH® RTO Technology
VOC control system to be installed at North Carolina OSB operation

De Pere, Wis., U.S.A., January 21, 2014—MEGTEC Systems, Inc. announces that Louisiana-
Pacific Corporation (LP) will install a MEGTEC CLEANSWITCH® RTO (regenerative thermal
oxidizer) at its OSB plant in Roxboro, North Carolina with delivery scheduled for the first quarter of
2014. The new CLEANSWITCH® RTO system, rated with a design flow of 250,000 scfm, will handle
the off-gas from five direct-fired rotary drum dryers. This is the third LP plant to install a MEGTEC
CLEANSWITCH® RTO system.

“LP chose the MEGTEC CLEANSWITCH® RTO to replace an outdated competitive system after a
detailed analysis of multiple equipment suppliers and alternative technologies,” states Rodney Schwartz,
Vice President of Sales with MEGTEC. “The simplicity of the valve and the energy savings provided by
structured media were two MEGTEC advantages identified by LP.” Adds Schwartz, “MEGTEC’s unique
ability to control quality and schedule by fabricating the equipment in our own plant in De Pere,
Wisconsin, compared to sub-contracting to outside fabrication shops, ensures the project timeline meets
LP’s requirements.”

LP’s Roxboro, NC operation has the capacity to produce 470 million square feet of OSB on a 3/8”
basis, comprised largely of softwood furnish.

The CLEANSWITCH® RTO offers 97+ percent VOC removal, exceptional operating economy, and
maintenance-friendly design as compared to other competing RTO technologies.

materials including OSB, structural framing products, and exterior siding for use in residential,
