Here, we answer some of the more frequent questions we receive from homeowners about glass and double glazing.

If you’ve been considering aluminium windows or UPVC windows, or if you would like to find out more about casement, bay or sash windows for any home in the Islington area, please feel free to call us if this page doesn’t answer your own question.

Which benefits can I expect from double glazing?

Because we create double glazing in units using quality glass and surrounds, we provide our Islington customers with finished aluminium windows and UPVC windows which boast high ‘U’ and ‘R’ values. Energy-saving performance can save homeowners up to £170.00 each year in utility costs, thus making double glazing a solid investment for the future.

Just as importantly, double glazing promotes heat retention and blocks out noise from the outside. If your Islington home is located on a busy street, you’ll be able to relax without the constant rumble of traffic disrupting your thoughts after a long day.

Bow or sash windows, or in any other style, we can help you turn your home into a haven. We can even supply double glazing for conservatories and orangeries, which we also install.

Do you use double glazing in aluminium and UPVC windows?

Yes. Homeowners in Islington retain full design flexibility as far as manufacture goes because we are able to supply double-glazed aluminium windows just as easily as we can supply double-glazed UPVC windows. Aluminium windows offer a striking design edge. Because the materials used in their manufacture recycle easily, there are numerous environmental benefits to enjoy.

UPVC windows manufactured with double glazing are the ideal choice for modern properties in Islington. They offer a low-maintenance installation that withstands even the harshest weather conditions. Our UPVC windows are sleek and stylish. They come in a surprisingly large range of profiles to suit the personal tastes of our customers.

Can I have double glazing fitted to sash windows too?

Of course! Sash windows are a more popular choice with customers in the Islington area who live in older Georgian or Victorian homes. Individual moving panels provide the flexibility needed for installations with restricted space. If you are looking to preserve the architectural qualities of an older property, we can customise the design of sash windows so that they integrate perfectly with homes in the same street.

Sash windows fitted with double glazing provide the same unique energy-saving benefits one would typically expect to find with most aluminium windows and UPVC windows. With such a versatile range of styles available, it’s easy to see why North London Windows is the preferred installation expert with discerning homeowners throughout the Islington area.
