'A' RATED WINDOWS  'A' rated windows are a huge improvement over most of the double glazed windows installed over the last 30 years, almost all of which will lose nearly twice as much heat as an 'A' rated window. With energy prices constantly rising, the benefit of installing an 'A' rated window will not only help the environment, but will save hundreds of pounds on household heating bills. Now is the time to replace Timber, PVC-U and Aluminium windows with Timberlook 'A' rated windows which have the appearance of timber without the maintenance costs. Please note the 'A' rated specification must be specified when ordering.
