As a leading manufacturer of BFRC enegy rated windows you can be sure that our windows are what we say they are. With our standard window rated as a 'C' by the BFRC, these are high efficiency windows with all of the heat saving benifits that you would expect.
In order to get the reating, we use 28mm argon filled glass units with Planitherm total glass. For our superb 'A' rated windows, we use the same tested Rehau S706 uPVC frame, but with Planitherm total and Diamonte glass with argon and the swiss spacer bar.
