  • Light Blocking: 90–95% blackout efficiency stops dawn light and exterior glare
  • Best for: Shift workers, light sleepers and nurseries needing uninterrupted rest

Better sleep and darkness – Thanks to 90–95% blackout efficiency

A dense, insulated 100% polyester weave prevents most visible light from passing through, cutting glare from street lamps and car headlights. The pencil pleat construction helps fabric hang closely to the window, improving the light-blocking effect.

Creates a darker bedroom environment for longer, making naps, night shifts and lie-ins easier to achieve without intrusive light.

Reduced heat loss and cooler summers – With thermal insulation

Insulating polyester construction reduces heat transfer through windows by adding a barrier between the room and external glass. The thicker weave reflects and resists external heat in summer while helping retain warmth in winter.

Helps keep rooms warmer in winter and cooler in summer, easing the load on heating and cooling and improving overall comfort.

Privacy and low-maintenance care – With OEKO-TEX certified polyester

OEKO-TEX certified 100% polyester ensures the fabric meets textile safety standards and delivers a soft, durable finish that tolerates machine washing. Certification indicates the material has been tested for harmful substances.

Dense fabric provides privacy from neighbours while remaining simple to care for at home, without the need for specialist cleaning.
