Sliding Windows Enfield: Supply & Installation
Sliding windows move sideways, so nothing swings out into a path, a wall or a worktop. Choose uPVC or aluminium, with a free survey and quote.
Sliding windows have two sashes in one frame. One or both slide sideways past each other on a track. There is no hinge, so nothing opens into the room or out into the garden.
We supply and fit them in uPVC and aluminium. Not sure if a sliding window is right for you? The sections below show where they work and where they don’t.
What Are Sliding Windows?
A sliding window moves left and right along a track. It is not the same as a sliding sash window. Sash windows slide up and down.
If you want the up-and-down style, see our sliding sash windows page. This page covers the sideways type.
Where Sliding Windows Work Best
- Wide, low openings. A very wide hinged window is heavy and awkward to handle. A sliding window spreads the weight along a track.
- Above a worktop or sink. There is no handle to stretch over and no sash to knock a tap or a plant.
- Beside paths and narrow side passages. Nothing swings out into someone’s way, which helps on terraced and semi-detached houses with a narrow side return.
- Upper floors and flats. Nothing swings out over a drop.
- Modern extensions. Slim aluminium frames give clean lines and large panes of glass.
What to Know Before You Choose Them
- Only half the window opens. A 1.2 metre window opens about 0.6 metres. A casement of the same size opens fully, so it gives more ventilation.
- Bedroom windows have rules. Upper-floor bedrooms need an opening wide enough to climb out of in an emergency. A sliding window opens only half its width, so we check the open size at the survey.
- The track needs cleaning. Dirt and grit collect in the track. Brush or vacuum it a few times a year, then wipe it clean. This keeps the sashes moving smoothly.
uPVC or Aluminium Sliding Windows
uPVC costs less, insulates well and needs very little upkeep. It comes in white, cream and woodgrain finishes. It suits most homes.
Aluminium gives slimmer frames and more glass. A thermal break in the frame stops heat passing through the metal. It comes in a wide range of colours, including black and anthracite grey. It suits modern homes and large openings, and it costs more.
Choose uPVC for most standard replacements. Choose aluminium if you want the slimmest frame or a modern look. See our aluminium casement windows page for more on aluminium.
Sliding Windows Compared with Other Styles
| Style | How it opens | Best for | Watch for |
|---|---|---|---|
| Sliding window | Sideways on a track | Wide openings, tight spaces | Only half opens |
| Casement | Hinged, swings out | Full ventilation | Needs room to swing |
| Tilt and turn | Tilts or swings in | Easy cleaning, safe ventilation | Needs room inside |
| Sliding sash | Slides up and down | Period character | Different look to modern windows |
Glass, Colours and Security
Standard glass is double glazing with low-emissivity glass. Triple glazing is available. Obscure glass suits bathrooms and side walls where privacy matters.
For colours, uPVC comes in white, cream and woodgrain. Aluminium comes in black, anthracite grey and many other colours.
Security depends on the lock fitted. Ask us about locking options when we quote.
Sliding Windows and Conservation Areas
Replacing windows on a visible elevation in an Enfield conservation area can need council approval. Article 4 directions cover most of Enfield’s conservation areas, including Enfield Town, Winchmore Hill, Southgate Green, Forty Hill and Bush Hill Park.
Windows at the back, out of sight of the road, are usually less affected. Flats have no permitted development rights. Listed buildings need listed building consent.
If your window faces the road, check with the council before ordering. We can tell you what to ask.
