Upgrading your windows from single glazed units to modern A-Rated uPVC units will help to reduce the loss of heat through your windows by a staggering 70% compared to a single glazed unit, or 50% if you have inefficient early double glazing. What does this mean in actual monetary savings? If you were to replace a C rated with one of our A+ Rated windows you would save enough energy each year to do a 2kg load of washing every other day for a year and run a full size A++ fridge freezer constantly!
