In this thrillingly tepid episode of Now That's Not A Very Very Interesting Podcast, we bravely venture into the lukewarm world of home insulation to answer a question that absolutely no one has been losing sleep over: Do curtains actually block out cold air?

Join us as we explore the surprisingly not-so-dramatic science behind thermal curtains, air drafts, and whether your window hangings are doing anything other than just… hanging. Expect a mildly educational, moderately meandering, and thoroughly unremarkable conversation that flirts with usefulness—but never quite commits.

Grab a lukewarm beverage, settle in, and prepare to be vaguely informed.
