A simple aluminium window can cost around $100. However, you will want to consider double glazed windows for energy efficiency. This will increase the price dramatically. You can expect it to be more for larger, multi-pane or odd-shaped windows.
Factors Impacting the Cost of Windows
Size of frame – Huge windows, doors, and odd-shaped windows can be many times more expensive. For example, a window frame of approximately 900 mm by 600 mm window can cost $100, while a 2100 mm by 1450 mm window lists for $750.
Glass thickness and panes – A look at aluminium window restoration cost demonstrates how glass treatment will affect your bottom line. Plain float glass runs about $40 per square metre for float glass. The low iron glass increases that to about $145. For double-glazed windows, the cost is around $200. Low emissions glass will increase that to $220. Laminate glass may be as much as $320 per square metre.
Hardware – You will want to ask about separate costs for locks and hinges. It is important to figure that into a final estimate. Unlike wood window hardware, the locks and hinges may be specific to the window manufacturers and, therefore, more costly.
Installation costs – Glaziers will charge about $40 to $50 per hour. The length of the installation will depend on factors such as the difficulty of removing current windows and the condition of your window openings.
