My son has a window in his room that faces the street. He hears street noise and get strong sunlight peeking through his blinds. This blackout shade is exactly what we needed, it’s perfect. It blocks out both noise and light. My son is much happier and he sleeps better. My husband said it was easy to install with no issues. We want to buy this for more windows in our house. It does exactly what it claims and I highly recommend!
