How Pasquill JJI-Joists Are Made
JJI-Joists, are beams with an I (I-Beams) 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.
Features & benefits of JJI Floor Joists / I-Beams
- Quicker to install ‐ Easier to install than a solid timber set: no herringbone strutting or blocking, no special tools required. Large flange profile enables ease of fixing. Saving you time on site, saving you money
- Lighter ‐ Typically half the weight of traditional solid timber sections making them easier to handle and install
- Improved service installation-9mm OSB/3 web allows easy access for wiring, plumbing and mechanical ventilation & heat recovery systems. Able to accommodate large service holes (max 125mm)
- Squeak free joists ‐ Structurally efficient profile also provides flat floors and ceilings
- Dimensionally stable, will not shrink, bow, twist, shrink or split which means Less building maintenance
- Part E Compliant ‐ Compliant with part E (Sound) legislation
- Uniform ‐ More uniform in dimension than sawn timber joists
- 220 mm section ‐ Section size matches typical blockwork coursing
- Fire Safe ‐ 30 and 60 minute fire certificate
- Quality Assured ‐ Consistent performance ‐ ETA, CE mark
- Supporting UK manufacturing ‐ UK Manufactured
- Established system ‐ Established in the UK in 1998
- Sustainably Sourced ‐ Chain of custody certification and labelling
- Technical Support ‐ Full national coverage with local knowledge
Their shrink and warp resistance helps create ‘quiet’ floor solutions and consistent dimensions provide extra stability. JJI-Joists / I-Beams also have the benefit of not needing insulation to gain compliance with Building Regulation Part E (sound) when installed at 400mm centres and above.
