Glazing Types

Double Glazed Casement Windows

The most popular choice of uPVC windows, so much so that ‘double glazing’ is now synonymous with buying windows. Affordable and energy-efficient, the two panes of glass in double-glazed windows ensure that your home’s heating stays indoors.

Triple Glazed Casement Windows

With all the benefits of double glazing windows but with an additional pane of glass, triple glazed windows offer even more heat retention meaning lower heating bills and fantastic energy-efficient credentials.

Casement Windows FAQ's

What Manchester Window Factory doesn’t know about windows isn’t worth knowing, so if your question isn’t answered below, our family-run business is here to help.

Casement windows are windows which sit within a frame, using positioned hinges to enable the window to fully open out.

New double glazing can help to reduce condensation. Improved room ventilation can further help in preventing it. When water vapour comes into contact with a cold window, it results in the water droplets which make up condensation. As double glazing contains multiple glass panes separated by air, the internal glass panels are able to remain closer to room temperature. Casement windows are particularly helpful in reducing condensation as they can open fully, providing better ventilation for the room as a whole. 

Glass is a great material for natural sound insulation and because double glazing windows consist of two glass panes, outside noise is naturally softened through this double defence. 

For homes near to busy roads, rails and runways, noise pollution can be reduced using acoustic glass.

The average lifespan for double glazing is anywhere between 20 and 30 years although much of this will depend on the type of glazing, materials used, and the weather that the double glazing has had to endure. At Manchester Window Factory we provide a fully comprehensive 10 year insurance-backed guarantee, covering all aspects of your windows and door installation.

The average price of a double glazed casement window is typically between £400 and £1,300 with materials.

We understand that jargon can make shopping for a double glazing window shopping a bit confusing. But we’ve got the expertise to guide you through any technical terms. 

  • Outer frame: 70mm multi-chambered profile which forms the outside of the window
  • Mullion: vertical profiles which fit into the outer frame or Mullion
  • Transom: horizontal profiles which fix into the outer frame of Transom
  • Sill: a surface which deflects water away from brickwork below, on which the window frames sit on top of. These can be 85mm, 150mm, 180mm, 225mm or 250mm.
  • Casement sash: the opening of the window which can be top-hung or side-hung
  • Dummy dash: a fixed sash for cosmetic purposes which does not open
  • Double glazed unit: two panes of glass separated by a warm edge ‘Swiss’ spacer bar filled with argon gas
