Frequently Asked Questions
Will semi-sheer linen curtains protect my couch from UV fading?
Semi-sheer linen blends diffuse light and reduce direct sun glare, which helps slow fading but won’t block all UV. For stronger protection, pair sheers with a blackout or thermal layer, or use UV-blocking film in tandem with curtains.
Do heavy blackout curtains actually reduce indoor temperature?
Yes—double-layer blackout panels and high-GSM fabrics reduce heat transfer through glass by reflecting and absorbing solar energy, which helps keep rooms cooler and can lower AC load when properly installed and closed during peak sun hours.
How should I measure for sliding door curtain panels?
Measure the full width of the door plus at least 6–12 inches on each side for overlap to block light and heat. For length, measure from the rod or track to your desired hem (floor or sill). For a full, gathered look, choose total panel width 1.5–2 times the door width.
