Plain-English summaries of the technical documents behind our doors: bushfire ratings, building code notes, construction, hinges and sound ratings. Tick the documents you need and we will email you the PDFs.
Bushfire (BAL) ratings
Homes in bushfire-prone areas get a Bushfire Attack Level (BAL) from a site assessment. These documents explain the levels and show how our bushfire rated doors and frames were assessed.
Guide
Understanding BAL ratings
There are six levels, from BAL-LOW to BAL-FZ (flame zone). Each one is a band of radiant heat, measured in kilowatts per square metre (kW/m²).
Doors are tested and assessed to AS 1530.8.1. The construction requirements for each level come from AS 3959.
BAL-12.5 covers ember attack up to 12.5 kW/m². Glazed doors need at least 4mm Grade A safety glass, and sliding doors must also meet AS 1288.
BAL-19 and BAL-29 doors need at least 6mm toughened glass.
Your BAL is set by the assessment for your property, so check it before you order.
How our doors help you meet the livable housing and energy rules in the National Construction Code (NCC) 2022. Your certifier has the final say on which doorways each rule applies to.
Guide
NCC 2022 livable housing: doorways
The livable housing provisions in NCC 2022 call for a clear opening of at least 820mm at selected doorways.
A door 870mm wide or wider gives that clear opening, for both hinged doors and cavity sliding doors.
The home also needs at least one step-free entry.
Based on the December 2023 guidance (version 1.0).
What is inside each door, how the glass is held in, and how pairs of doors are rebated. Every product page also lists its construction under Specifications.
Guide
Door construction types
Honeycomb core (hollow core): a light, economical internal door with a honeycomb core between two skins.
Solicore particleboard core (SCX1): a solid core that adds weight, a solid feel and better sound reduction.
Solid timber pine core (STPC blockboard): solid timber blocks inside, for heavy-use doors.
Solid HMR MDF core: a moisture-resistant MDF core used in many entrance and feature doors.
Engineered joinery: stiles and rails built from engineered timber for stability.
Barn doors come with a premium hollow core or an ultimate solid infill core.
A pair of doors is rebated so that one leaf closes over the other.
Standard rebate: seen from outside, the right-hand door opens away first (clockwise).
Reverse rebate: seen from outside, the left-hand door opens away first (anti-clockwise).
Optional extras include an extra lock block, glass or vent openings, a stable door conversion, an astragal or T-bar for a pair, grooved bottom rails for barn door tracks, and routing for a mortice lock or hinges. Ask us for a price on any extra the configurator does not show.
Sheet the wall with fibre cement at least 6mm thick (Type A or Type B, Category 3, to AS/NZS 2908.2), such as Villaboard or CeminSeal.
Fix the track through every pre-punched hole, fix the back post to the stud with at least 5 evenly spaced screws or nails, and screw through the bottom plate.
Set the unit plumb and level, then sheet and tile.
Fix the sheet at 200mm centres and never let screws reach inside the cavity pocket.
Timber-framed and steel-framed cavity units were load tested with fibre cement sheeting to carry wall tiles.
Timber units were tested to AS 1720.1-2010 Appendix D and steel units to AS/NZS 4600:2018 Section 8, with test loads of 2.7 to 2.9 times the intended tile load.
Tested for tile loads of up to 40 kg/m² (timber frame) and 45 kg/m² (steel frame), for doors up to 2340 x 1200mm.
Sound ratings
Our doors are sound tested so you can compare them. Product pages show a rating under Specifications where one has been tested.
Guide
Sound ratings explained
Two ratings are used. STC (Sound Transmission Class) is worked out to ASTM E413-87 over 125 to 4000 Hz.
Rw (weighted sound reduction index) is worked out to ISO 717-1 over 100 to 3150 Hz.
The higher the number, the more sound the door blocks.
A door only reaches its rating with seals of an equivalent rating around it.
Test method
Sound testing methodology
Doors are tested to ISO 10140-2:2010, the laboratory method for airborne sound insulation.
The door is installed between two vibration-isolated reverberation rooms. Sound is played in one room and measured in the other.
The document explains how samples are installed, how sound transmission is measured and how results are evaluated.
Product notices
Changes to the range that affect what you can order.
Notice
Product change: coloured and frosted glass (June 2021)
Some Frosted Black Orchid, Frosted Kookaburra Jewel, Kookaburra Green Leaves and Wysteria glass options were discontinued.
The change affected some Carringbush, Regency, Savoy 820, Vaucluse Premier, Humecraft, Joinery and Moulded Panel doors.
Our configurator only offers glass from the current price list.
These summaries are a guide only. The full documents set out the conditions, limits and variations that apply, and your builder or certifier should work from them. Ratings apply to the door set installed as described in each document.
