Cascade Structural Laminators manufactures CSL TREATED Glulams using South-
ern Pine lamination stock. Southern Pine is the ideal species for treating, since it doesn’t require incising to receive the pressure treat wood preservatives that make it exceptionally resistant to rot and decay. CSL TREATED is a stock 26F-1.9E glulam beam that is ideal for exterior, above ground, high-moisture applications such as decks, porches, and balconies. Engineered with a balanced lay-up, making CSL TREATED easy to install.

Permapost Hi-Clear II Treatment – CSL TREATED glulams are pressure-treated with a premium industrial wood preservative and water-repellent treatment that chemically resists insects, rot, mildew, decay and mold. Permapost Hi-Clear II has a low toxicity; therefore, CSL TREATED glulams are easy and safe to work with using a few simple precautions. Cascade recommends that all field trimming, hole drilling or minor surface exposure be resealed with 2% solution copper naphthenate, which is available at home centers. Permapost Hi-Clear II is the only wood preservative that is approved by the U.S. Food and Drug Administration in compliance with the EPA for treated wood products.
