how much does a double glazing unit cost
When most people look at double glazing they get a glazier to quote. They normally wont fit double glazed units to existing windows but instead replace the whole frame, leading to a cost of around $800 per square meter, or $16,000 for a normal house with 20 sq metres of window.We reduce the price as follows:-.If you have good quality wooden frames, you can use the existing frame.his reduces the cost further to $4,000 a house. We only provide double glazed units with argon rather than air in the gap. While this is slightly more expensive, it improves the window performance a further 10%. As a good starting point, our base product (2 sheets of 4 mm glass) costs $165 per square metre.
