Trend Windows & Doors Pty Limited, Port Macquarie, NSW

The Trend Windows business was formed in July 1968 by a partnership, manufacturing Western Red Cedar windows and Doors. Trend's head office is still located at the original site at Girraween NSW. In 1973 Trend began manufacturing basic aluminium-sliding windows five years after opening to accommodate the rising demand in aluminium products. Trend was one of the first window manufacturers to later assemble aluminium double hung and awning windows, and one of the first company to manufacture an individually glazed aluminium window with its patented Ovolo Glazing System. Trend expanded its manufacturing operations in the early 1970's to Tamworth, Canberra, Newcastle, Victoria, Queensland and finally South Australia. From this time, until the early 1990's, the company was acquired by number of owners including Rio Tinto.
