Energy Efficiency​

Well-designed windows and doors can improve the level of comfort in your home all year round. This can reduce the requirements for heating in winter, whilst reducing the need for cooling in the summer.

Based on an average house containing 8% area of glazing in the entire building fabric, as much as 49% of the heat lost during Winter and as much as 87% of the heat gained during Summer can come from the windows.

Window configuration, orientation and glass performance can play a large role in the energy efficiency of your home. Well designed and correctly placed Glass Co Metro windows and doors, combined with the use of performance glass, can reduce your energy bills and reduce your impact on our environment.

Unlike other window systems on the market, Glass Co Metro windows and doors have been designed to accept thick glass and double glazing, without the need for additional unsightly adapters and added material.

What are your glass options?

Glass is the most influential factor in window and door efficiency, accounting for up to 90% of thermal performance. Your Glass Co Metro windows and doors combined with high performance glass can make your home increasingly more comfortable and energy efficient.

Whether it be choosing our stand 5mm Clear Float to let as much light and energy transfer through all the way up to a Low-e Laminated Double Glazed Unit with Argon fill, we can accommodate your needs


The Window Energy Rating Scheme enables windows to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia. To participate in WERS, window makers must obtain energy ratings for their products from a rating organisation that is accredited by the AFRC (Australian Fenestration Rating Council).
Glass Co Metro is a proud member of this scheme.

Why you should choose energy rated windows

Energy Rating for windows is here to stay. The federal government’s Australian Greenhouse Office helped to underwrite WERS as part of its commitment to improving energy efficiency and reducing greenhouse gas emissions from the built environment.

Home resale value, comfort and amenity are improved by the use of high-performance windows. We have moved from an industry traditionally considered as providing a commodity building material to be sold on price alone into offering true consumer goods viewed as performance appliances for energy, noise and security.
WERS conforms to the alternative solution path for energy efficiency within the Building Code of Australia.

Natural light:

By choosing the correct performance glass you can enjoy your views and natural light while controlling UV and glare.

Solar heat gain:

Solar heat is generated when sunlight passes through a window and heats the surfaces and air inside a home. Depending on where you live, homes can benefit from the natural warming effect of solar heat during winter and its reduction during summer. Good design and the appropriate selection of performance glass for the windows orientation can keep the home cooler in summer and warmer in winter.

Thermal conductivity:

When there is a difference in temperature between the inside and outside of a house you have heat flow. The greater the difference, the greater the heat flow, especially through windows using ordinary single glazing. The correct performance glass dramatically improves the energy efficiency performance of the window.
