Blockout Vinyl is an opaque material that will not let the sun or any light through it. It is also not transparent when looking at it from the back. It’s heavier and more durable than our 13oz Scrim Vinyl or 13oz Indoor Vinyl materials plus it’s low curl so even if it’s stored in a tube, it will stay smooth when rolled out. Blackout Vinyl is perfect for hanging banners or signs where banner opacity is needed.
