Been around about 40 years.
Aside from missed screws, it is good construction. Straighter,
stronger and cheaper than solid wood.
The use of liquid nails for the sub-floor helps prevent squeaks in a
few years. Adhesives are rather strong.
Engineered wood I-beams were first introduced in the late 1960's and
were used mainly for high-end home construction. However, today up to
half the homes built in the United States now use engineered wood
I-beams. Engineered wood I-beams are considered an excellent
alternative to sawn lumber for floor joists due to their strength and
overall lower installation costs.
