Double Glazing Australasia (DGA) adheres to strict quality control processes to ensure our customers receive the best possible products and service.

DGA focuses on a number of business areas to enhance quality in our operations. These areas of continual improvement are summarised below.

  • The highest manufacturing standards. Our trained and experienced personnel use state-of-the-art CNC (computed numerically controlled) machinery to ensure repeatable precision when fabricating our window and door systems to customer specifications. At DGA we use a barcode cross-matching system to match the aluminium sections with various cutting and machining processes during manufacture.
  • Technological innovation. Our products are the result of research, industry knowledge and the continual testing and improvement of techniques used to construct our windows, doors and insulated glass units. You can be assured that our double glazed windows, doors and skylights are amongst the leading products in the industry.
  • Outstanding service. At DGA we feel that a personal approach is required to ensure we fully meet our customers’ needs. After you make initial contact with us, we will come to your project site to inspect the building and obtain accurate measurements. We will discuss the project with you in detail so you know exactly what you require, what you will receive, and the costs, timeframe and process associated with our service to you. Whether you are a residential or commercial customer, you receive the same level of communication and quality of service.
