Flooring systems comprise floor panels and cassettes, i-joists and open web joists.
The use of timber ﬂoors has been around for centuries and the performance is dependent on the use of the ﬂoor. Timber floor structures are engineered, designed and built to achieve structural compliance as well as acoustic, ﬁre and in some instances, thermal performance. For most ﬂoor designs and installations it is the serviceability checks that dictate the spacing and size of ﬂoor joists or the depth of solid ﬂoors. It should be noted that where the ﬁnish of the ceiling is exposed timber, such as cross laminated timber, the structural capacity will include a ﬁre resistance check which may dictate the ﬁnished depth of ﬂoor required. Timber ﬂoors are no more sensitive to different loading types than other materials.
Floor Panels and Cassettes
Floor panels and cassettes are modular floor systems, which can be manufactured using I-Joists, open web joists or traditional joists to meet customer requirements. They are pre-decked and manufactured offsite, providing an easy-to-fit, low maintenance flooring option, with the instant stability of a working platform.
Cross laminated timber
A structural two-way spanning solid wood panel product that can be used to form floors as well as roofs and shear walls. It is produced by stacking a number of layers of timber, known as lamellas, at 90º to the layer below and subsequently glued to create panels of up to 24m in length and 2,950mm in width, which can encompass between three and seven layers.

Structurally engineered timber joists, combining high-grade softwood with an engineered composite panel. I-Joists are lightweight, easy to install and have an excellent strength to weight ratio. The most notable difference from dimensional lumber is that the I-joists carries heavy loads with less lumber than a dimensional solid wood joist. The advantage of I-joists is they are less likely to bow, crown, twist, cup, check or split as would a dimensional piece of lumber. I-joists' dimensional soundness and little or no shrinkage help eliminate squeaky floors.
Open Web Joists
Composite timber and steel joists, forming an open web design which are also known as Posi Joists. They are lightweight, strong, easy to install and available in long lengths. Open web joists provide the lightness of timber with the strength of a steel web. The open web design means that using these joists can eliminate cutting and drilling when installing services.
