 NPi I-Joist—Made from high-grade LVL and OSB, NPi I-Joists allow architects and engineers to specify a product that performs to a higher standard than 2x sawn lumber joists. They can design structures that are more open, which consumers find more appealing. NPi I-Joists are also more dimensionally stable than sawn lumber joists. As a builder, NPi I-Joists save you time and money. They will not warp, twist or shrink and they are more uniform in size.
ALLOW DESIGN FLEXIBILITY
The availability of long lengths allows multiple span installations, thus speeding construction by eliminating the need to lap joists over bearing walls or support beams. This also means fewer pieces to handle. The availability of long lengths and relatively deep joists also gives designers the freedom to create more open spaces and reduces the need for supporting walls, columns, or beams.
DIMENSIONALLY STABLE
I-Joists will not warp, twist, or shrink, and are more uniform in their dimensions than sawn lumber joists. The L/480 maximum live load deflection criteria of APA PRITMs combined with their straightness and uniformity provides a stiffer, more uniform floor with fewer squeaks, resulting in higher customer satisfaction.
LIGHTWEIGHT
Because I-Joists typically weigh less than half of comparable conventional framing lumber, they can be installed quickly and efficiently.
