These factors are tested by the BFRC (British Fenestration Ratings Council) and a window is allocated a window energy rating which is an indication of how efficient the window’s performance is when used with a particular glazing specification. uPVC windows are rated from G up to A+ rating; A+ being the highest performing windows and G being the least energy efficient.
Digression on older children and the poor1.
Heat loss is quantified as a u-value and is measured in kW loss per m2 of window area per year, the lower the u-value the more efficient your windows will be. Here is a brief history of u-values over the decades an how u-values have improved:

I do therefore humbly offer it to publick consideration, that of the hundred and twenty thousand children, already computed, twenty thousand may be reserved for breed, whereof only one fourth part to be males; which is more than we allow to sheep, black cattle, or swine, and my reason is, that these children are seldom the fruits of marriage, a circumstance not much regarded by our savages, therefore, one male will be sufficient to serve four females. That the remaining hundred thousand may, at a year old, be offered in sale to the persons of quality and fortune, through the kingdom, always advising the mother to let them suck plentifully in the last month, so as to render them plump, and fat for a good table. A child will make two dishes at an entertainment for friends, and when the family dines alone, the fore or hind quarter will make a reasonable dish, and seasoned with a little pepper or salt, will be very good boiled on the fourth day, especially in winter.
Composite Door Energy Efficiency
The uPVC window and door industry has recently been anticipating the release of the governments new scheme named the ‘Green Deal’. The Green Deal had a soft opening a little over a month ago to judge the response of the new scheme, however no funding is yet available, this will come in the first quarter of 2013.
