How Pasquill JJI-Joists are made.
JJI-Joists, 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 by James Jones & Sons for Pasquill to precise specification using high grade solid timber flanges bonded to an OSB web.
Using JJI-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. JJI-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.
