Double Glazed Windows for Houses in London

New double glazed windows

While our Double Glazed windows and doors no longer have to keep out the thick smog, having secure, air-tight windows is a must when it comes to London-living. In the last few years, we’ve had thick snowfalls which have brought TFL to its knees on a number of occasions, and summers that have kept many residents hiding indoors. There’s also the noise aspect to consider, particularly if you live next to a major road in a central part of the city (zones 1-3 are particular culprits). So what type of windows can you get to fit double-glazing in London?

Casement windows (between £300 and £500)

Casement windows are the classy-designed style that swings out from a hinge located at one side of the frame. Traditionally, this hinge would be found that the side, but now it can be fixed at the top or bottom of the frame. These are some of the more affordable varieties of windows and are available in UPVC, aluminium, and timber.

French casement windows (between £300 and £500)

French casement windows are perhaps one of the most traditional in appearance; you’ll see older versions in Italian villages and small continental towns, the kind that swing out from the side. What makes these different from traditional casement windows is that there are two sets of hinges that hold two sashes in place, with a pillar dividing the two. Nowadays, the frames are made from much sturdier plastics, and the hinges can actually exist on the top and bottom, not just on the sides. There is also now no need to have a pillar dividing the two, and an illusion of a pillar is created when the windows are closed. Having an obstruction is also not useful when you consider that having a fire escape window is a modern design requirement.

Tilt and Turn (between £270 and £650)

Tilt and turn UPVC Windows

Many people will know these windows when they’ve turned the handle expecting it open, only for it to push towards them. These windows have two methods of opening: vertically at the top, and like a casement window (swing it horizontally). These are useful if you just want to occasionally pop the window open for some fresh air, or have the option of opening them wider.

Sliding Sash windows (between £700 and £1,500)

If you have a period London home, you may already have sash windows. The sash windowpane can be slid upwards or downwards (depending on the design), using pulleys and balancing mechanisms. Their airflow created by a sash window is said to be great for ventilation. You can indeed buy modern equivalents that are double-glazed, and just as authentic.

Bay (and maybe even Bow) windows (£1,000 – £3,000)

These are another traditional form of window, where the frame sits outside of the building’s facade. There is a clear difference between the two: bay windows are composed of walls and window frames,  while bow windows can be fixed on a straight wall: the window panes curve outside the of the facade separately.

The type of window you opt for may well depend on the period your home was created in. You may prefer to keep the style but replace single-glazed for a more modern update. If your home is relatively modern, you may just want to install some newer, more secure windows.
