The inner ‘cavity’ of a standard sealed unit, contrary to popular belief is not a vacuum. It’s just filled with dry air. Now as it happens, air itself is a very good insulator, but it’s not as good as Argon gas. By removing the air from the cavity and replacing it with argon, an extra barrier to heat loss is created.
But don’t just take our word for it. The transmission of heat is easily measured and quantified in what’s called a ‘U-Value’. The lower the U-Value, the lower the rate of heat transfer, and the better the insulator.
The British Fenestration Rating Council (BFRC), in conjunction with the UK glazing industry and European partners has designed a window rating system to meet this need for simple and accurate information.
The BFRC provides third party certification for the total thermal performance of windows using a ‘fair, accurate and credible’ assessment scheme.
In other words with its dual action, our energy rated windows are more than twice as effective at retaining heat than standard clear double glazing, and 30% better than Pilkington K.
