BlocOut™ XL

The BlocOut range is our award-winning range of shades that has been proven to reduce heat loss through the window by up to 43%. Where a curtain traps heat from the radiator, preventing it from circulating round a room, the BlocOut shade creates an energy-efficient barrier between the shade and the window, leaving the radiator free to heat the room more effectively. As a result draughts and heat loss are dramatically reduced. The BlocOut XL is specifically designed for larger windows up to 2400mm wide and up to 2400mm drop.
