What to look for in a window

A Buyers Guide


Burglars usually gain entry to your home through a window or door. So you’re windows security is high on the agenda. it’s important for you to select windows with adequate locking devices. You also need to think about the window itself – the frame must be of high quality and able to withstand hard knocks.

Peerless Windows offers the Espagnolette locking system, an extremely robust multi-point lock that offers exceptional security. When locked, your door or window will bolt itself into the top of the frame and the floor, as well as at the handle, giving it even structural strength throughout. Any would-be burglars would have to attack the lock at all points to gain entrance, delaying their attempts until the alarm is raised.

Energy EfficiencyCurrent minimum building regulations require either ‘C’ rated windows or a ‘u’ value of 1.6 or lower. Make your home warmer by upgrading to an ‘A’ rated window or improve to a ‘u’ value. Windows play an integral role in creating an energy efficient home and situated in the right spot, they will help maintain a comfortable home, all year round. However, misplaced windows can greatly increase the energy you use. For example, if you live in a cold climate, and your windows are predominantly facing south, you will get no natural light to help heat up your home.

Our expert consultants will help you find the perfect position for your windows, and once installed our high-grade low emissivity windows will ensure your home stays cool in the summer and warm in the winter.


Consider your personal circumstances. If you are worried about excess noise outside why not consider double glazing with acoustic glass or our new triple glazed window.


Think about the design of windows required and how much breeze you would like in that area. Fixed pane windows don’t open so they provide no ventilation, trickle vents can help with ventilation, damp and other possible issues. Sash or double-hung windows open right up so they provide maximum ventilation. When you are considering ventilation, you can’t focus on just one window; you need to think about the whole room.

All this may seem a lot to think about, but our friendly staff are on hand to give you help and advice and to guide you through your home improvement experience.

Making a Difference

The Orphanage in Breaza, Prior to the installation
Charity trip to Romania
“Peerless Windows,flew out to Romania to aid a charity project, ‘Convoy 2000’ involving the refurbishment of a home for mentally handicapped children aged between seven and sixteen.

The mission was set up by the Metropolitan and Essex Police who approached several window companies by letter and by phone to enlist their help.

‘Peerless windows were the only company that were willing and able to offer their help,’ comments David O’Grady, PC with the Metropolitan Police.

The job involved the installation of seventeen uPVC windows,’ explains Aidan Holloway, director of Peerless Windows.

‘We donated four of our team’s time to install them. The project took five days to complete and we will certainly be going back to Romania next year to help with another job.’ ” – passage from www.TheGlazine.com
