This, coupled with a much increased self-weight of the beam (11.4 pounds (5.2 kg) for engineered wood vs. 25.2 pounds (11.4 kg) for a flitch beam), decreases the viability of the system.
This, combined with a significantly higher self-weight of the beam (11.4 pounds (5.2 kg) for engineered wood versus 25.2 pounds (11.4 kg) for a flitch beam), reduces the feasibility of the system.
