Hello All,
I am looking for ideas on how to insulate a part of a window that is fixed and does not open (shown in the picture below). I have come across some solutions here where window sealing mechanism is mentioned but the one that we have does not need that as its perfectly sealed. However, it does not stop the heat from going out. This is a high rose, so the outer part of the window is not accessible.
I have come across some options like covering the whole glass with bubble wrap (https://www.abc.net.au/news/2022-06-23/diy-window-insulation-tips-draught-proofing-winter-cold-house... unsure how effective that is or if there is a better solution.
Hello @gautam86
Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your window.
Using thermal curtains is one way to keep the cold out. Thermal curtains are an excellent way to improve insulation and reduce heat loss through windows, particularly during colder months. These curtains are typically made with multiple layers, including a dense or foam-backed lining that acts as a barrier against cold drafts and helps retain indoor warmth. For a full positive seal you can cover the opening with Bastion 1200 x 600 x 30mm XPS Multi Use Foam Board. Simply cut to size using a snap knife and insert into window opening.
In regards to your question, yes bubble wrap will help in regulating the temperature coming through the window. I propose placing one sheet on the black frame and using clear packaging tape on all sides to hold it in place. Then place one more layer on the outer edge of the wall opening so that you will have two layers. This air gap serves as the barrier and prevents the cold air from coming straight through your window. I recommend having a look at this discussion - Insulate windows with plastic for winter by @JL.
Let me call on our experienced members @prettyliving and @Renowayoflife for their recommendations.
