High Performer Building -
minimum specification
Set out below is the minimum specification criteria for a building to be certified as a High Performer Building.
Any building awarded the High Performer Building status must, wherever applicable, utilise the product range below. While in some cases the benefits of an individual product may seem to have a low impact, the collective value and compounding benefits of the products being used together lift the building to a level of quality that simply can’t be achieved using standard specifications.
Every project has its unique challenges and sometimes our minimum spec cannot be achieved. Trade Innovations assess each individual application to ensure the integrity of the brand is upheld and the occupants are truly receiving a high spec, quality building. No building will be awarded the High Performer Building status without us being confident in the quality of the products used and assured that no corners have been cut.
Below is our minimum spec, recommended spec and performance reasoning for the minimum criteria.
Concrete Slab Foundations
MINIMUM SPEC: ALLIED CONCRETE Ready and Super Slabs with Fly Ash additive for reduced CO2 and greater slab durability.

MINIMUM SPEC: J-FRAME Structural Laminated Veneer Lumber (LVL) gauged framing timber.
RECOMMENDED SPEC: Extend the use of J-FRAME to be included in the Joist, Trusses and Rafter components of the building.
WHY? J-FRAME outperforms standard stress graded timber in strength and dimensional stability, giving you a stronger and straighter frame.
Flooring Substrate/Midfloor
MINIMUM SPEC: MAGLOK DragonBoard® engineered “fit for purpose” fibre reinforced Magnesium (MgSo4) flooring board substrate.
RECOMMENDED SPEC: As above
WHY? MAGLOK feels and sounds solid to walk on, is unaffected by moisture and won’t cause squeaky floors.

Internal Linings
MINIMUM SPEC: USG Boral recommends plasterboard systems which meet or exceed minimum building code
requirements (this may vary depending on your building design).
RECOMMENDED SPEC:
USG Boral Multistop™ 4 On the bottom half of all walls for improved impact and water resistance and USG Boral SHEETROCK® On the top half and ceilings.
USG Boral Sheetrock™ full height walls where technical board is required for compliance (e.g. Bracing/Water/ Sound/Fire/Impact Resistance).
USG Boral FIBEROCK® Aqua-Tough™ in high traffic and impact zones such as stairwells and garages. (FIBEROCK can be used as a higher spec alternative to Multistop™ 4.)
WHY? USG Boral linings are the result of over 100 years of scientific experimentation and innovation success in creating better living environments.
*It is recommended to use USG Boral Joint Compounds with USG Boral Plasterboard to achieve a full, 10-Year Wall System Warranty. results and performance guarantees.
Cladding - Fibre Cement
MINIMUM SPEC: BGC Premium Fibre Cement Claddings should be used where any fibre cement is used on the building. Fibre cement provides a strong durable cladding and is considered our minimum specification if the building is to be painted dark colours.
RECOMMENDED SPEC: BGC have a range of innovative profiles for various applications. We recommend assessing where it can be utilised on your build.
WHY? BGC have a proven record of quality and is known to be consistently dimensionally accurate and has a smooth, easily paintable finish.
