Honeycomb blinds feature a cellular design that traps still air, helping reduce heat loss through windows in winter and heat gain in summer. But how effective are they, and can they really help lower heating costs? We'll explore how honeycomb blinds work, what independent NZ testing has found, and what makes them an effective insulating window covering
Honeycomb blinds, also known as cellular blinds, are made from fabric layers securely joined together at intervals to form rows of hollow, honeycomb-shaped cells. Unlike standard roller blinds, their cellular construction creates insulating air pockets. Available in light-filtering and blockout fabrics, they offer a practical combination of insulation, privacy and light control for New Zealand homes
Honeycomb blinds work by trapping pockets of still air within their cellular structure, creating an insulating barrier between the window and the room. In winter, this helps reduce heat loss through the glass, while in summer, it helps limit unwanted heat gain. Their naturally close-fitting design also helps improve insulation by reducing air movement around the edges of the blind
Yes, honeycomb blinds can help reduce heating costs by limiting heat loss through windows, allowing your home to retain warmth for longer. Actual savings depend on factors such as window size, glazing, climate and how regularly the blinds are closed. Independent testing by Consumer NZ has demonstrated the impressive insulating performance of honeycomb blinds, which we'll explore further below
Independent testing conducted by Consumer NZ in 2019 found that honeycomb blinds were the most effective window covering tested for retaining heat. Under controlled laboratory conditions, they reduced heat loss through an uncovered, single-glazed window by more than 60%, outperforming the other blinds and curtains tested. Their insulating cellular structure and naturally close-fitting design were key contributors to this result
Not all window blinds provide the same level of insulation. Consumer NZ's independent testing found that honeycomb blinds outperformed the other window coverings tested, reducing heat loss through a single-glazed window by more than 60% compared with leaving it uncovered. Their insulating cellular structure helps retain warmth in winter and limit unwanted heat gain in summer — making them an excellent choice for a more energy-efficient, comfortable New Zealand home
When choosing honeycomb blinds for energy efficiency, consider the cell construction and fabric type. Double-cell honeycomb blinds generally provide better insulation than single-cell options, thanks to their additional insulating air pockets. Blockout fabrics typically offer a further thermal advantage, while light-filtering fabrics provide excellent insulation alongside natural daylight. The right combination depends on whether your priority is maximum insulation, light control or a balance of both
