In terms of cutting and notching, which statement is true regarding engineered wood products?

Engineered wood products, such as laminated veneer lumber and oriented strand board, are designed for specific structural applications to ensure safety and longevity. When it comes to modifications like cutting and notching, the manufacturer's guidelines are critical. These guidelines are developed based on extensive testing and engineering analysis to determine how much alteration, if any, can be made without compromising the product's strength and functionality.

When cutting or notching engineered wood products, the recommendation of the manufacturer must be followed closely. This includes their guidelines on what types and extents of modifications are permissible. By adhering to these specifications, building inspectors and contractors can ensure that the structural integrity of the engineered product is maintained.

This approach not only ensures safety but also aligns with building codes that require compliance with manufacturers' standards. Therefore, if the manufacturer specifies that certain modifications can be made under defined circumstances, those recommendations should be strictly followed to avoid issues related to structural performance.
