I am considering using Insul Bright for lining about 10 very large drapes for my living room. It seems to be very quilted and appropriate for things like pot holders and am concerned about how the drapes will hang with such a quilted lining.

If someone can suggest a better lining, I would really appreciate it. We have many large south and west facing windows, so I need something that will also reflect radiant heat, like mylar or something. Is there another mylar lining product available?

I would really appreciate any advice on this.

thanks
