2022-04-06
It must be a great experience living in a historic house where the history and new lifestyle can be combined in harmony. While, it could also be an exhausting experience when it comes to doing the maintenance, especially for replacing the windows, and keep its integrity of history.


Figure out Why and how.

So what should you do before making the decision to replace the original antique windows of your historic house? First of all, you need to figure out why you need to change the window. Here are two main reasons commonly listed by the owners.
1. First, the original window is flawed. It could have a broken pane and not works well in thermal insulation, noise reduction, etc;
2. Second, the original window is good but its performance in thermal insulation and energy-saving are not very well. Due to historic reasons, most original antique windows consists of single or insulated glasses which can not fit the energy-saving standard now especially when it comes to the new policy of carbon neutrality. What is more, the worse the performance in energy saving is, the more the energy consumption of your house lose , which means more bills need to be paid.
For the first reason, you could choose to replace the single or insulated glass that fits your window structure. 

But for the second one, the same structure of the insulated glass can not make your house lose less energy because the only way to increase the window performance in energy saving is to increase its thickness (like triple insulated glass). However, a triple insulated glass is thicker and can not fit the original window frame. And you need to replace both the window and its frame.
