Question

Because I-joists do not expand and contract with changes in moisture content, it is necessary to use engineered ___ in place of solid wood joist headers when framing with I-joists

Answer 1

When framing with I-joists, it is necessary to use engineered headers in place of solid wood joist headers.

Step-by-step explanation:

When framing with I-joists, it is necessary to use engineered headers in place of solid wood joist headers. This is because I-joists do not expand and contract with changes in moisture content, unlike solid wood joists. Using engineered headers ensures that the structure remains stable and reduces the risk of problems such as warping or buckling that can occur due to changes in moisture content.
