Rating & Certification

Due to our design and high performance components, Miglas windows and doors can be manufactured to meet the most exacting demands for thermal efficiency, solar heat gain, and air infiltration as well as eco aspects or bushfire ratings.


Miglas is a member of the AWA (Australian Window Association). It is our ambition to actively participate in the development of standards, ratings and certificates.

Having our staff attend seminars offered by various industry related organisations, enables us to meet your requirements with up to date knowledge.

WERS - Window Energy Rating Scheme

Forestry Standards

Timber is a major component of Miglas’ products. The timber is AFS certified for sustainable forest management and is recognised by the European standard PEFC. FSC timber is available on request.

Australian Standard 2047

Is the basic standard for windows and doors. Every window manufactured in or imported to Australia has to comply to the standard. The sub sections give more detailed information about the tests and the ratings that are required for different regions. The standard includes structural integrity, water resistance and air infiltration.

Bushfire & Noise Reduction
