U Glass for Conservatories

U Glass Insulation

The U value is a measure of the amount of heat loss...

Glaziers talk about the U values that different types of glass may have. The U value is a measure of the amount of heat loss through a certain material. So the U value of glass refers to how much or how little heat the glass will retain. The rate of this heat loss is calculated in one square metre of glass for every heat degree of difference on either side of the glass. The lowest U value glass is the glass that has the greatest insulating properties.

If you want to save on your heating bills then it is best to choose glass with the lowest U value as this will mean that there is less heat loss. However, before you make the decision about what U value you should have in your conservatory you need to bear in mind that the lower the U value the more expensive the glass. You should weigh up the extra cost of the glass against how much you think you might save before you make any decisions.
