You should use insulated curtains in rooms with the most exposure to natural sunlight. Hanging insulated curtains in these rooms will generate a beautiful and relaxing feel, thanks to the light exclusion. The thick material will also block the outside noise, so make sure you get the most adhesive fabric for rooms with continuous exposure to loud sounds. If you’re planning to install insulated curtains in the bathroom, the material should be water-resistant so that it takes humidity and doesn’t grow mold.
