Window energy ratings reveal energy efficiency increase

  • 19 Aug 2015

After being launched in 2013, ‘A ‘ rated windows doubled during 2014 as a percentage of the total number of rated product. By the end of the year, the figure stood at nearly 5%.

Meanwhile, the market share of ‘A’ rated windows continued to increase from 58% – 65% throughout the year.

In 2012, ‘A’ was at 49%, reaching 55% before the launch of ‘A ‘ in September 2013.

A decline in inefficiency

Contrastingly, there has been a decline in ‘B’ rated product from 7.1% in January to 6.2% in December. This follows a two year decline – 2012 averaged at 8.7%, whilst 2013 dropped to 7%.

The average percentage of ‘C’ rated installed was 24% in 2014, compared to 36% in 2013.

An energy efficient industry

The percentages support BFRC’s argument that window energy ratings have moved the industry.

The products manufactured and installed are climbing further and further up the energy efficiency ratings bands.

The company is eager to see how the first ‘A ; rated windows will affect the figures further. These are predicted to hit the market within the next few months.
