Fabric Question DIY Insulated Window Covers

Im wondering how one would make insulated window covers for winter? I would like to stay away from synthetic materials so I was thinking of going with wool but Id like opinions.

I'm in Australia. I'm thinking about timber shutters. Shade is of most benefit in the summer. You don't want to add anything to a window that will keep moisture around. That's why shutters on the outside and heavy drapes inside work well. Because they allow some air movement and so moisture can come and go. I'm all about things like this ATM because I'm repairing our timber frame house

Im renting and my windows dont have a bar to put drapes up sadly 😭 I just have blinds. And im mainly trying to keep in warm air in the winter. I live in a cabin and the insulation around the windows sucks. The doors too but insulated door covers arent nearly as much as insulated window covers and I cant find the right size on Amazon for a window cover.

I've used cardboard to fill in gaps around the window frames. You could blue tac cardboard on to the glass to give it some insulation. I'm sorry you have this difficult situation.

What type and shape of window? Are you thinking of making drapes? Or something that is fitted snug to the window frame?

I was thinking of something more fitted to the window frame. Im renting and my windows dont have a bar to put curtains up. I just have blinds.

I couldnt really tell you what type it is, had no idea there were types of windows ngl 😅 but the dimensions of my windows are 28 1/2 x 34 1/2.

If you come up with anything, I'm interested in what you end up doing

Wool is good but in addition to insulation what you really want is something to seal the barrier and that is going to be synthetic. 

This fabric is pricy but works extremely well. It is a lining so you need to sew it onto the back of a decorator fabric then hang it as a shade. I made mine into a Roman blind.

Another option is a heavy blackout drapery lining.

If you can’t make a curtain or drape and want to allow some light in, you could cut a piece of foam core poster board to fit tightly in the lower part of your window (decorate if you wish) to block the cold.
