I-Joists

I-joists, also known as I-beams, are beams with an I- or H-shaped cross-section. The horizontal elements are flanges, while the vertical element is called the web. They are manufactured to precise specification using laminated veneer lumber or kiln dried C24 softwood flanges bonded to an OSB web. Using I-joists is a very efficient form for carrying both bending and shear in the plane of the web – their superior strength-to-weight ratio allows longer spans and easier handling.

 

Their shrink and warp resistance helps create ‘quiet’ floor solutions and consistent dimensions provide extra stability. I-joists also have the benefit of not needing insulation to gain compliance with Building Regulation Part E (sound) when installed at 400mm centres and above.
