Applications
hyJOIST is suitable for structural applications including residential and commercial floor and roof rafter systems, and industrial purlins. hyJOIST is not intended to support brickwork or other heavy masonry products.
Treatment for Durability
hyJOIST H2-S Terminator is available in all sizes and is part of the Carter Holt Harvey Terminator range. hyJOIST H2-S Terminator is treated against termites south of the Tropic of Capricorn. The treatment is applied to the glueline during manufacture to achieve full termite protection to the core of the beam. No further sealing is required on cut ends or holes.
Moisture content
hyJOIST, at time of despatch from the manufacturing site has a moisture content of between 8-15%.
Structural grading
The properties of hyJOIST have been determined by testing as required by AS/NZS 4357, and are not substitutable for F grades, MGP grade, or other proprietary I-joists. Design verification using the Carter Holt Harvey free designIT software or selection guide (located in the hyJOIST design guide) is required to ensure suitability.
Certification & Compliance
hyJOIST flanges are manufactured in accordance with AS/NZS 4357, and the plywood web is manufactured in accordance with AS/NZS 2269. hyJOIST is product certified by the Engineered Wood Products Association of Australasia (EWPAA), which is JAS-ANZ certified. Participation and compliance with this process based quality control scheme ensures ‘Evidence of Suitability’ in accordance with Clause 1.2.2 of the Building Code of Australia (BCA).

Handling and Installation
Storage
The following recommendations regarding storage are made in order to ensure that the full benefits of hyJOIST as a dry, straight and true material are available at the time of installation.
- Stack on level bearers to keep flat and straight.
- Stack well clear of the ground for good ventilation.
- Store under cover to keep dry prior to installation.
Note: After installation, exposure to sun and rain for normal periods of construction is not a cause for concern.
General Installation
hyJOIST should be installed strictly in accordance with the details supplied in the hyJOIST Installation Guide.
Technical Note: Rimboard
Carter Holt Harvey sometimes receive requests to assist specifiers with technical advice on other generic products when used in conjunction with hySPAN LVL and hyJOIST Engineered I-Joists. The following Technical Note entitled 'Rimboard' is an example of this - Download.
Racking Through Floors
Modern house designs often feature large open plan living areas with large windows or doors to 'bring the outdoors inside'. In two storey houses this normally means deep section engineered floor joists capable of spanning over lower level open areas.
More information is contained in the hyJOIST design guide and hyJOIST installation guide
Racking Through Floors - Detail
hyJOIST Cantilevers
hyJOIST floor joists are capable of meeting the loading requirements for cantilevers as defined in AS/NZS 1170. For external use, hyJOIST floor joists must be protected from becoming wet by a fully waterproof deck. In the case of non-waterproofed decks the use of outriggers of suitable natural durability or preservative treated to H3 as per AS/NZS 1604 is suggested. Outriggers can also provide a step down to the deck reducing the likelihood of water ingress at openings.
More information is contained in the hyJOIST design guide and hyJOIST installation guide.
Health & Safety
The MSDS available from the website details all health and safety precautions required when using hyJOIST
Environmental certification
hyJOIST is manufactured from 100% renewable plantation timber. All timber is sourced from Australian Forestry Standard and/or FSC certified forests.
