SmartJoist is an Engineered Wood I-Joist manufactured with Laminated Veneer Lumber flanges top and bottom joined with an Oriented Strand Board (OSB) web.

Cost effective, convenient and high performing, the Tilling range of SmartJoist spans further than any other I-Joist available on the market.

Biggest Range

SmartJoist offers the most comprehensive range in the market, with 200mm, 240mm, 300mm, 360mm and 400mm heights available. Tilling also exclusively offers a 255mm Wet Area Set-Down joist to complement the 300mm joists for a complete floor system solution.  All SmartJoist sizes are available across Australia through a network of knowledgeable timber merchants.

Convenience of service penetrations

All SmartJoist products include a 40mm knock-out hole at 450mm centres along the web, for small diameter services or wiring. Larger service holes can easily be accommodated.  Tilling Timber runs CNC machinery to provide pre-cut service penetrations in SmartJoist, free of charge.

Design Service

For the ultimate in convenience, the SmartFrame Design Centre can design floor systems from engineering and architectural drawings. This approach provides accuracy, efficiency and peace of mind for any builder. A clear, easy to read colour A3 layout is provided along with an installation guide, and the SmartJoist is supplied labelled and with pre-cut penetrations cut in the web of the SmartJoists where requested.

Best Performance

SmartJoists are engineered for heavy performance. We start with ultrasonically graded LVL, bonded with exterior adhesive for more load carrying capacity.  The webs are made from stable, strong Oriented Strand Board (OSB) for superior strength and consistent performance.  All material is H2S treated for termite protection south of the Tropic of Capricorn. Full H2 treatment is also available.
