First used in premium home construction, I-joists are now used in 60% of North American new home construction and growing. Because I-joists are spaced further apart than conventional timber joists, the cost of having engineered I-joists is no more expensive. Nascor I-joists are guaranteed for the entire life of the home, something that is simply not possible with conventional timber joists.
