100% Blackout Curtain Lining – Ultra-Light PU-Coated Liner

This is a 100% blackout curtain lining supplied as a 2-panel set. It is installed behind an existing curtain to upgrade it to full blackout plus thermal insulation. **100% light blocking (full blackout)**: blocks morning sunlight, street lamps and oncoming headlights to create a dark environment suited to deep sleep. **Ultra-light construction**: the back face uses a special high-performance PU coating and weighs roughly 50% less than conventional linings of the same class. It puts less load on existing curtain rails and is easier to wash and re-hang. **Sound insulation and thermal performance**: provides sound insulation to reduce outside noise. Thermal performance is test-verified — up to 63.9% blocking in the black-panel test (52.9% inside the test layer) and a 41.10% heat-retention rate. It blocks heat radiation at the window in summer and reduces warm-air loss in winter, helping air conditioners work more efficiently. **Sizes and installation**: 7 sizes, all supplied as 2-panel sets, covering 105cm / 155cm / 205cm widths with drops from 65cm to 255cm. Used together with an existing curtain and hung on the existing rail — no new hardware needed. For bedrooms, street-facing rooms or windows with strong light pollution, it adds blackout and insulation without changing the look of the existing curtain.
