100% Blackout 330 GSM Curtains 52 x 90 (2 Panels) - Full Shade Thermal

In this review the reviewer looks at the Rutterllow 100% Blackout 330 GSM Curtains to judge whether they deliver true darkening and thermal benefit for bedrooms and living rooms. The bottom line: these curtains are best for anyone who needs reliable, complete light blocking and noticeable heat retention in a standard window, because the fabric and construction create a genuinely dark room and a substantial, insulated feel.

Key Features

• True 100% blackout: The thick 330 GSM fabric blocks sunlight fully to create a dark sleeping environment even during the day.
• Thermal insulation: The dense material helps balance room temperature and can reduce heat transfer, which may save on cooling and heating costs.
• Sold as two panels: Each panel measures 52 in x 90 in, providing a combined width of 104 in for full window coverage without gaps.
• Grommet top design: Eight copper grommets per panel with a 1.16 in inner diameter slide easily on standard rods and add a classic look.
• Easy care: Machine washable in cold water and tumble dry low for straightforward maintenance when panels need cleaning.
• Heavy, substantial feel: The weight and drape give a finished appearance and improve light and sound dampening in the room.

Who It's For

These curtains are ideal for shift workers, light-sensitive sleepers, home theater rooms, and photographers or content creators who need to control studio light without building complex rigs. The full blackout capability and thermal properties suit anyone wanting privacy and energy savings from a single window treatment.

Shoppers who need custom lengths, exotic colors, or sheer layers should look elsewhere; the panels are fixed at 52 in x 90 in and the available color may vary slightly from images, so do not buy if you require an exact color match or a semi-transparent option.

Cons
