Our Premium Plus Aluminium Windows are our top of the range, BFRC certified aluminium windows. They are beautifully slim, highly energy efficient and environmentally friendly windows that achieve an 'A' rating in energy efficiency. They have been certified to have achieved this rating with a double glazed sealed unit. You will get a good return on the extra cost of these GREEN windows as they could save you up to as much as 10% on your heating bills.
These windows are an upgrade of our Premium window system using only the slim internally glazed flat vent and the three slim outerframe options. The slim sight-lines optimise solar gain and when used in conjunction with 90% argon gas filled, soft coat low-e (Low Iron) Glass it can achieve excellent thermal values and energy efficiency. You can also have our chelton vent with chelton handle as an A-Rated window, but these require triple glazing for an A rating.
