Knauf Australia offers a variety of online calculation tools for the professional to quickly and accurately find solutions for their project.

The Knauf calculators are developed in-house, and comply with the National Construction Code (NCC) 2019. The NCC 2019 has recently been adopted by all States and NT, and will be adopted by ACT from 1 September 2019.

The driving force behind Knauf’s online calculators is Digital Engineering Manager and Senior Technical Services Engineer Shailesh Koirala. Shailesh combines his knowledge of IT and coding with his extensive knowledge of the NCC and its requirements to develop and maintain these tools.

Shailesh is part of the Knauf Technical Services Team and deals with customers’ technical enquiries on a daily basis. “This opportunity has enabled me to identify the areas where calculators could go a long way in helping clients and customers find solutions for their project,” he said.

Anybody involved with building construction in Australia will benefit from these tools, including architects, builders, certifiers, contractors, other building materials manufacturers and suppliers, and even home owners.

“My main intention was to develop a variety of tools that are helpful and easy to use,” Shailesh said.

Shailesh monitors the updates and changes in the NCC and other relevant Australian Standards on a regular basis and amends the calculators accordingly. For example, the Knauf Reverberation Time Calculator now has recommended reverberation time based upon the latest Australia/ New Zealand Standard AS/NZS 2107:2016.

The Knauf calculators are a helpful aid for professionals, but it should be emphasised that the results of the calculators are only to be used as a guide, as many aspects of the construction are not comprehensively covered and more importantly the calculators are not intended to replace the NCC or relevant professional services.

All calculators are available online, or click on the individual links below.  

KNAUF SYSTEM SELECTOR

This calculator will help you to find the right Knauf System to match your project specific architectural requirements and to find a suitable Knauf non-load bearing lightweight steel frame design for the selected system.

Please also refer to Blueprint, our comprehensive technical manual for lightweight steel frame construction offering complete Knauf systems, for more information.

KNAUF FRAME FINDER

Non-load bearing walls and ceilings can be easily built with Knauf's cold formed light gauge steel framing systems. Knauf offers a wide range of steel studs, tracks, top cross rails, furring channels and top hats for both internal and external non-load bearing applications.

This calculator can be used to find the right Knauf framing system to suit the project specific requirements.

KNAUF RADIUS CALCULATOR

A calculator to help you work out the radius and length of a furring channel or top cross rail needed to build a curved ceiling, both concave and convex.

KNAUF WALL THERMAL CALCULATOR

Use this calculator to estimate the Total R-Value of a wall of Class 1 and 10 buildings. The thermal resistance of an external wall has significant influence on the energy efficiency of a building. The total R-Value, as per 2019 NCC Volume Two, is the sum of the thermal resistances (R-values) of the individual component layers in a composite element including any building material, insulating material, airspace and associated surface resistances.

BCA 2019 REQUIREMENTS FINDER

This calculator is the latest addition to our range of online tools, and has been designed to help you determine what fire, sound insulation and thermal properties are required for your specific building and application type to comply with the acceptable or deemed-to-satisfy provisions of the Building Code of Australia 2019.

The National Construction Code (NCC) 2019 has been adopted by all States and NT from 1 May 2019, and will be adopted by ACT from 1 September 2019. NCC Volume One and Volume Two jointly make up the Building Code of Australia (BCA).

KNAUF WIND LOAD CALCULATOR

Use this tool to calculate the wind loads applicable to your internal non-load bearing steel frame walls and ceilings if your building is in non-cyclonic wind regions, region A and region B, your building height is less than 100 m and there are no dominant openings on any external surface.

KNAUF INTERHOME CALCULATOR

This calculator can be used to estimate the quantity of materials needed to build the Knauf InterHome wall. InterHome is a separating wall system suitable for adjoining residential dwellings such as duplexes or townhouses.

InterHome has been designed to satisfy the fire safety and sound insulation requirements of the Building Code of Australia (BCA) for separating walls.

KNAUF REVERBERATION TIME CALCULATOR

This calculator can be used to find the recommended reverberation time as per AS/NZS 2107: 2016 and estimate the Reverberation Time (RT60, RT or T) of a room. In an enclosed space, sound gets reflected from hard and smooth surfaces creating reverberation, the persistence of a sound even after its source has stopped. Adding sound absorbers like Knauf’ Stratopanel or Cleaneo Adit and Cleaneo Up significantly reduces the reverberation noise in an enclosed space.
