In unprotected exterior applications, or where structural framing will be exposed to elevated moisture conditions, iLevel® offers Trus Joist® Wolmanized® Parallam® parallel strand lumber (PSL). The unique composition of Parallam PSL allows the preservative treatment to penetrate to the core of the product, providing protection from termites, fungal decay, and recurring ground water contact on posts across the entire cross section of the framing member. Two limited warranties on the product provide builders and homeowners with the assurance of protection. (www.ilevel.com)

Wolmanized Parallam PSL is available in headers, beams, columns and posts. It is ideally suited for unprotected exterior or wet-service applications such as decking supports, carports, cantilevered roofs and shelters, and can be painted or stained with an oil-based finish.

Wolmanized Parallam PSL is pressure-treated with proprietary formulas developed by Arch Wood Protection, Inc. iLevel warrants Wolmanized Parallam PSL against manufacturing defects, and Arch Treatment Technologies warrants against termites and fungal decay.

Made from long, thin strands of wood bonded together in a microwave process, Parallam PSL is consistently strong and straight. The manufacturing process uses nearly the entire log for high-grade structural lumber, making efficient use of the raw material.

Wolmanized Parallam PSL is one part of a complete and integrated package of framing materials that include trusted products and brands such as Trus Joist® TimberStrand® laminated strand lumber (LSL), TJI® joists, Structurwood® panels and Weyerhaeuser Premium Joists™.
