Double Glazing Windows – New & Replacement


As one of the first things folks often change when “doing up the property”, the double glazing you fit is going to have an impact on a few things. First of which is the general appearance of your home.

Which window type?

You could fit double glazing windows into a few categories in terms of how they look and work:

  • Casement
  • Sash
  • Tilt / Turn
  • Bifold

double glazing windowsCasement windows are probably what most folks first picture in their mind if asked to describe double glazing. Opening from the side and swinging outwards is the usual configuration, but you also get top hinged “fanlights”.

A well known variation on this design is the French Window. Actually, this style is just a matched pair of casement windows within a single outer frame.

Sash windows open in a different way by sliding up and down. Known as vertical sliding sashes you can see them all over the UK in Victorian, Georgian and Edwardian style properties (New & Old). A lesser used version here in the UK is the horizontal sliding sash – you can see this style a lot at the drive thru window at any fast food outlet.

Tilt / Turn or Tilt / slide windows are really a mutation of horizontal sash and casement windows. The tilt / turn window can open like a casement, albeit inwards only or be tilted inwards from the top. The tilt / slide version has the same tiltin feature but can also slide to the side like a horizontal sash window

Bifold windows are just smaller versions of bifold doors. The windows slide to the side and fold in a zig-zag or concertina fashion to sit at the side of the frame out of the way.

Each of these design has it’s own particular appeal or advantage in different situations, but it’s well worth taking the time to think carefully about which would suit you best – before you part with your cash.
