I-Joists, otherwise known as I-beams, are a factory-made, structurally engineered timber product, providing outstanding strength and durability. The timber joist has an I-shaped cross- section comprising top and bottom flanges made of softwood or LVL (laminated veneer lumber) fixed to a tall vertical web of OSB (oriented strand board) or similar.
I-Joists are lightweight and easy to handle. They are incredibly strong in relation to their size and weight. They can span to around six metres.
I-Joists aren’t prone to warping or shrinkage, making them the ideal choice for quiet floors! They can be used to build flat or pitched roofs and are suited to residential and commercial builds of all scales.
