Claims to check
“Theater Grade” and “Extreme” are product names. The Sun Zero site does not define them or publish a test method. The “100% blackout” claim describes the fabric; no curtain on a rod stops light leaking around the edges. To get close to full darkness, hang the panels wide and high and close the center gap. The guide do blackout curtains help you sleep covers why darkness at night matters and how to handle gaps.
Returns
The Sun Zero site does not state a return policy. Returns follow the terms of the retailer you buy from.
