Buying an energy efficient conservatory?
Energy Efficient Conservatories.
Conservatories need to be energy efficient to meet the demands of modern living and manufacturers have made great improvements in this area over the years.
Energy efficient Glass:
Low-e (low emissivity) glass is considered to be the most effective, and the objective of this glazed unit is to allow natural light to easily pass through whilst reflecting heat away from the surface – either inside or outside the home. This helps to lower heat build-up inside during sunny weather and keeps more of your heat inside the home during colder weather.
The surface of the glass is coated with a very thin film of metal oxide and it is this which reflects the heat. You should take care when choosing a low-e glass as some of the lower quality versions can slightly obscure the light & cause a “hazing” effect.
The gap between the panes of the sealed unit can also be filled with inert gasses such as xenon, argon or krypton which further reduces heat transmission.
Finally, the panes within the sealed units have spacers to separate the glass; using non-metallic warm edge spacers will also increase thermal efficiency.
Windows now come with energy rating labels, rated from A to G , with A being the highest rating. You can find out more on ratings here: http://www.bfrc.org/
