100% Blackout 340 GSM Curtain Panels - Full Light Blocking Drapes

In this review the RUTTERLLOW 100% Blackout 340 GSM curtain panels are presented for anyone who needs complete darkness and thermal insulation in a bedroom or media space. The biggest reason to buy is the proven light-blocking performance: sold as two panels that total 104 in wide by 63 in long, these panels deliver true 100% blackout and noticeable heat retention, which helps create a quiet, dark sleeping environment at any hour.

Key Features

• Complete blackout: The dense 340 GSM fabric is designed to provide 100% light blocking, keeping rooms dark even in bright daylight.
• Thermal insulation: The heavyweight construction helps retain heat and balance room temperature for improved comfort.
• Two-panel set: Sold as 2 panels, each 52 in by 63 in, offering a combined 104 in width to cover standard windows without gaps.
• Grommet top design: Each curtain has 8 copper grommets with a 1.6 in inner diameter for smooth sliding on most curtain rods.
• Easy care: Machine washable in cold water and tumble dry low, making upkeep straightforward for regular use.

Who It's For

This product suits light-sensitive sleepers, shift workers, and home media or studio users who require a reliably dark room; reviewers noted the panels even work well with studio LED or strobe lighting. The curtains are also a good fit for anyone seeking a simple, grommet-top installation and a heavier fabric for sound dampening and heat control.

Those who need extra-long lengths, patterned decor, or a wide range of color matching should look elsewhere, since this set is fixed at 52 in x 63 in per panel and the available color has received mixed feedback from buyers about shade accuracy.
