PWT Laminated Veneer Lumber (PWT LVL) is produced to specific tolerances based on manufacturing equipment capabilities. Due to the manufacturing processes there may be slight variations between the product and nominal dimensions. This slight deviation in dimensions is called tolerance. When PWT LVL leaves the manufacturing facility, its dimension tolerances are within the manufacturer’s limits and the product moisture content is between 6-10%.
PWT LVL may swell, shrink, and change shape in response to moisture and adverse weather, even with the additional protection of factory applied sealants. Moisture content for in service conditions will vary widely.
PWT LVL products should be protected by keeping the products wrapped, off the ground, stacked, and supported appropriately. Using these guidelines will help keep product clean, shed rain, and promote air circulation to dry off any incidental moisture.
