Beautiful, modern double-glazed windows 

Our Windows are made using the latest technology advances. Today’s double glazed windows can make a huge difference to the appearance and energy efficiency of your home. Independent industry research shows modern uPVC windows, like the ones we sell, to be an astonishing 55% more efficient than equivalent double glazing windows produced at the turn of the millennium. They’ll save you money on ever-increasing energy bills, make your home more comfortable, and give your house a sparkling modern make-over into the bargain. 

Our range of double glazing windows is designed to help to keep your family home safe, toasty and free from outside noise pollution.

Energy efficient double glazing 

It has been demonstrated that over 26% of the heat lost from your home can come from your windows. Be assured that all window units produced by Phair Windows achieve the current building regulation standards or better and contain our unique, highly energy-efficient technology. Ultimately, this means it will have heat retaining qualities to help you save money on your energy bills. A-rated windows are fitted as standard.

If your current windows are only single glazed, then upgrading to double glazing could have an even larger impact on the efficiency of your home. The extra pane of glass means that there’s an additional layer of material for heat to get through before escaping, so more is retained inside the house.
