How Does Sleepout Control Temperature
How Does Sleepout Control Temperature
Sleepout® blackout fabric uses an HOA-approved white backing that reflects sunlight away from your home, helping to prevent bedrooms from overheating. In colder seasons, the dense material blocks drafts and adds an extra layer of insulation while also reducing outside noise. Many customers see energy savings of 30 percent or more by using Sleepout® fabric on their windows.
