Check Latest Price on AmazonWhich One Should You Choose?
If you want the best overall balance of cost, insulation and noise reduction: buy BGment Blackout Curtains for Bedroom (B09JBPVJ7C). They’re budget-friendly, easy to hang, and consistently praised for look and value, making them the best day-to-day choice for bedrooms and standard living-room windows.
If you have very tall windows or floor-to-ceiling glass and need maximum coverage: choose BGment Blackout Curtains (52 x 120 Inch, B0BW3MTHDS). The extra drop traps more cold air at the glass and improves room-darkening and sound dampening, but be sure your rod and hardware are sturdy enough for the weight.
If you want a compromise between length and manageability: choose BGment Blackout Curtains (52 x 108 Inch, B0BBM42DNZ). They offer deeper insulation than the 84-inch set while being easier to handle than the 120-inch panels.
Best for Specific Scenarios
- Budget bedroom blackout: BGment 70 x 84 Inch (B09JBPVJ7C) — looks high-end for the price and blocks most light while improving thermal comfort.
- Tall windows / lofts: BGment 52 x 120 Inch (B0BW3MTHDS) — extra-long panels cover full-height windows and trap more cold air at the glass.
- Living room noise reduction: BGment 52 x 108 Inch (B0BBM42DNZ) — fuller coverage than short panels with less weight than ultra-long options, helping soften street and household noise.
Frequently Asked Questions
Do blackout curtains really save on heating bills?
Yes. Thermal blackout curtains reduce heat loss by adding a barrier of fabric that traps air next to the window and reduces convection. Savings depend on window quality, installation (tight overlap is important) and local climate; combining curtains with shades or weatherstripping increases effectiveness.
Are these BGment curtains machine washable?
Yes. The BGment polyester panels are designed to be machine washable on a gentle, cold cycle and tumble dried low. Always check care instructions for your chosen size and color to avoid shrinkage or damage.
Which is better for noise reduction: blackout curtains or cellular shades?
Thicker blackout curtains help reduce high-frequency noise and provide decent sound absorption. Cellular shades with sealed honeycomb cells can offer better thermal insulation and some sound dampening, but the best result often comes from layering a cellular shade with a heavy blackout curtain.
