JJI-Joists

JJI-Joists are an incredibly efficient choice when it comes to handling both bending and shear forces within the plane of the web.

Description

JJI-Joists, also known as I-Beams or I-Joists, boast exceptional shrink and warp resistance. This characteristic is particularly beneficial as it contributes to creating ‘quiet’ floor solutions, which many clients appreciate.

Additionally, the consistent dimensions of these joists provide extra stability, ensuring a reliable and durable construction.

An added advantage of JJI-Joists is that they do not require additional insulation to comply with Building Regulation Part E (sound) when installed at 400mm centres or greater. This feature can save both time and resources during the construction process.
