‘A’ Rated or ‘C’ rated
Our Standard
window is ‘C’ rated which is currently accepted as the standard most
suitable for general energy efficient use.
‘A’ Rated windows
can be supplied at an extra cost.
The only difference between an ‘A’ rated window and a ‘C’ rated
window is that the double glazed unit used in an ‘A’ rated window
has a warm edge seal which gives a slightly better thermal value. So
if you want to save the planet, spend a little more for your windows
and ask for ‘A’ rated windows, alternatively buy what the vast
majority of customers choose, ‘C’ rated.
