Home construction practices and procedures had changed drastically over the years. Floor joists once constructed with 2×10’s has been replaced with engineered I-beams and LVLs (Laminated Veneer Lumber) capable of spanning distances without supporting structural members which were often required to carry the load of additional floors. Affordable and lightweight, engineered I-beam floor joists have subsequently replaced the antiquated double or triple 2×12 floor joists, with proven engineered designs that are far superior to old traditional methods. Engineered I-beams provide superior strength, uniformity and level perfection of all completed subfloors, essential for the installation of all interior flooring finishing material, especially hardwood flooring.
Constructed with the visible appearance of an “I”
I-beams consist of a top and bottom rib normally 2×4’s dimensional lumber. Sandwiched between the top and bottom ribs, specially designed OSB, (Oriented Strand Board) completes the simple but extremely load carrying capacity of the I-beam with precision and accuracy. Integrated into the design of the I-beam are pre-designed and placed “knockouts” which allow for the installation of plumbing and electrical artifacts through the I-beams at pre-determined locations, saving time in pre-drilling standard 2×12 floor joists, with a reduction in labor costs.
Capable of spanning lengths of up to 24′ or more without supporting basement floor jacks, engineered I-beam floor joists allow full basement completion without loss of floor space and the “boxing in” of supporting columns when using old 2×12 joist framing methods. Available in widths from 10″ to 16″, and a variety of top and bottom rib …Read More
