Key points

  • Fabric. Look for a high light-blocking rating and a lining that stops leaks.
  • Mounting. An outside mount overlapping the window by 5 to 10 cm or a track with side channels reduces edge leaks.
  • Safety. Loose cords are a strangulation hazard for young children; use cordless or motorised mechanisms.
