Frequently Asked Questions
Will these curtains noticeably reduce heat in a south-facing room?
Yes—thermal-lined velvet panels that block 90%+ of light reduce solar gain by preventing direct sunlight from hitting interior surfaces. Proper fit (full coverage and minimal gaps) and using heavier or reflective-backed liners will increase performance. Combine curtains with blinds or shades for best results.
How do I measure my windows for these panels?
Measure window width and add 8–12 inches per side if possible so curtains can fully cover and stack off the glass. For length, measure from rod position to where you want the curtain to fall (sill, below sill, or to the floor). Choose panels that match or exceed that length and full width (panels usually sold as pairs).
Are velvet blackout curtains machine washable?
Most listings for these Lazzzy velvet panels state machine wash cold and tumble dry; however, heavier velvet may be easier to care for with spot cleaning or gentle cycles and steaming to remove wrinkles. Always follow the care instructions on the product tag to avoid damage.
