Suitable for roof, wall and floor applications, the new I-Joists provide a full portfolio of joist widths; 47mm (A+), 63mm (B+), 72mm (C) & 97mm (D), for I-Joist depths ranging from 350mm to 450mm.
To ensure full system integration, appropriate metalwork to complement the new widths and depths is available from suppliers ITW and Simpson Strong Tie.
Business Development Manager Mark Tilston commented: “These new sizes will allow Architects much greater flexibility when specifying JJIs for roofs, walls and high-load floor applications. It will be more cost effective too: why use a D flange JJI when an A+ will do the job?”
The new I-Joist sizes are compatible with the company’s updated JoistMaster software (V3.31) and can be preservative treated to comply with NHBC requirements. All JJI-Joists are FSC accredited and independently carbon-assured to PAS 2050:2011.
