Re: Engineered wood (I-Joist, LVL) Versus Solid timber joist21

Capacity and deflection. I guess what expert is saying that man made lumber has the correct capacity but maybe allows for more deflection than natural timber when designing? Probably because its more predictable. More deflection more bounce.
When engineers select man perhaps they don't consider application too much. Deflection in a roof wouldn't be so bad. Its a static load but in a floor with a dynamic load...
