What is a Wolmanized PSL?
Weyerhaeuser Trus Joist® Parallam® Plus PSL products, with Wolmanized® preservative protection, are treated with copper azole (beams) or CCA (columns). These preservatives are U.S. EPA-registered pesticides that are used to protect against insect (termite) attack and fungal decay.
What is a parallam PSL beam?
Parallam® PSL Beams are strong, beautiful, and can help turn open floor plans into reality. They are made using long thin strands of wood and a super strong adhesive glue to give you perfectly predictable beams and columns.
Is PSL pressure treated?
Parallam® PSL products enter an airtight treatment cylinder—a highly controlled, pressurized environment where they are exposed to the treatment process.
What is PSL and LVL?
Parallel Strand Lumber (PSL) is manufactured from veneers laid into long, parallel strands and bonded together. PSL beams are primarily used in beam and header applications where high strength is required. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.
What is PSL made of?
Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses.
What is a PSL post?
Is PSL stronger than LVL?
PSL beams are generally more expensive than glulam, LSL, or LVL beams. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL. Available sizes, strengths, and stiffnesses are similar to PSL but are generally cheaper, making it a commonly specified beam type.
How far can a PSL beam span?
* The span and load tables in this guide cover beam spans up to 60 feet; however, 2.2E Parallam® PSL beams can be delivered in lengths up to 66 feet.
Can PSL beams get wet?
For beam or column applications exposed to weather or high moisture, a preservative treated product – such as Parallam® Plus PSL – may be an option. Properly store Weyerhaeuser OSB and EWP products such that they are protected from moisture.
Can PSL be fire treated?
It is important to note that designers must always verify compliance of this approach with the authority having jurisdiction, especially for applications that require fire retardant treatment in the code. This is because Parallam PSL cannot be treated with fire retardant.
