Winter Series: Part 5/6 Why Cellular Blinds Are The Most Energy Efficient

Winter is one of our favourite times of the year. Hot drinks, soft couches with a warm blanket, crackling fireplaces, and a good Netflix binge. The only thing we’re not super keen on is the heating bill that comes at the end of a cold season.

Electricity prices have risen significantly year on year, to the point where it’s the primary cost-of-living concern for Australians, with no real relief in sight – Andy Kollmorgen, Writer for Choice Magazine

When it comes to building materials and construction, the way thermal resistance (how much thermal flow there is between spaces) is rated is called an R-Value. An average exterior wall has an R-Value of 13.1 while an average window only 1.16.

It’s quite understandable then that windows lose more heat per square meter in winter and gain more heat in summer than any other surface in your home.

While we love our windows – especially in Australia – they account for up to 40% of our annual heating and cooling costs.

Blinds have traditionally been simply a way to have either a decorative window treatment or a privacy screen from nosy neighbours. However, in recent years, we are becoming more conscious of our footprint on the planet and the need to be more cost and energy-efficient. Blinds have been created to be a part of our overall way to combat some of the problems of heating, cooling and design.

So, we’re going to talk about cellular blinds (commonly called honeycomb) and why they’re the most energy-efficient blinds on the market right now!

Cellular Blinds – Honeycomb Design

Luxaflex cellular duette shades have a unique design. The honeycomb or cell produces insulating pockets of air. Inert or unmoving air reduces the thermal flow of air effectively insulating the window. Inert air is a poor heat conductor working for us to help keep our homes better temperature regulated. Heat flow through the window is slowed trapping warm air inside in winter and outside in summer.

Single, Double, Insulated Cells

The more cells or larger the cells you have in the blind design means the blind will be more energy efficient. Depending on the look you would like to achieve or level of energy efficiency may impact on your choice of blinds. In the case of cellular blinds the most efficient is the insulated cells.

The insulated cell consists of a double hexagon – one inside of the other – which acts as a double-wall, makes the blind opaque for complete blockage of sunlight and achieves an R-value of R-7 or higher. If you want a light filtering blind you will still be able to achieve an R-5 value with a double hexagon staggered design. This design works by one stack thermally connecting to the room, the other to the window. The thermal transfer is slowed and heat has less chance of being transferred.

If you’re still unsure about Cellular blinds being the best choice when it comes to being energy efficient maybe consider this. If a home has Cellular blinds installed 43% of heating and cooling costs can be saved year-round! Energy-efficient? Yes.
