Why choose AWR
Simple to use
Turn the handle and push. Casements open and close easily, even over a kitchen sink.
Clear, open views
Large panes and slim frames let in plenty of daylight and give you a clear view out.
Suits almost any house
From terraces to detached new-builds, there is a casement layout that fits the look.
Lots of design choice
Choose where it opens, how the panes are split and which colour frame you want.
Strong, secure locking
Our casements use a full Yale locking suite and are PAS 24 security rated.
What makes a casement window different
A casement is hinged on one side and swings outwards, held open by a casement stay. It can be used singly or in pairs within a common frame, and it is often combined with fixed panes and smaller top openers in one window.
That flexibility is the reason casements are on so many British homes. You can have a wide picture-style pane with a narrow opener, two matching side-hung sashes, or a top-hung vent for airflow on a rainy day. Everything is made to measure, so the layout follows your opening.
Styles to suit the age of your house
A modern casement with a large clear pane suits newer homes and rooms where you want the view. For older properties, a cottage style casement with smaller panes adds Tudor or Georgian character without going back to timber.
Our surveyor will look at your door and roofline as well as the windows next door, then suggest a layout that suits the whole house.
Pick a frame colour you'll love
White is still the most popular choice, and our heavy-duty white frames have a high gloss finish that does not need painting. If you want something different, casements also come in anthracite grey, rosewood, honey oak and other woodgrain finishes.
Colour is a simple way to tie your windows to a new composite door or roofline, or to give a plain house more presence from the street.
Where casement windows work best
Casements are a good all-rounder for almost any home, and there are a few places where they really shine.
- Kitchens, where a side-hung window over the sink is easy to reach and open.
- Living rooms, where a large fixed pane with a narrow opener gives a wide, clear view.
- Newer homes, where clean frames suit modern brickwork and render.
- Older cottages, where a cottage style casement adds traditional character.
- Anywhere with space outside for the window to swing open without blocking a path.
Built to keep your home secure
Because a casement opens outwards, the locks and hinges do a lot of work. Ours are PAS 24 security rated and use a full Yale locking suite, including anti-hike shoot bolts and key lockable handles.
Every casement is fitted by our own trained installers and covered by our 10-year guarantee on uPVC windows.

Questions people ask
What is a casement window?
A casement window is hinged at the side and opens outwards, usually held in place by a casement stay. It can be used on its own or in pairs within one frame, and is often combined with fixed panes. It is one of the most popular window styles in UK homes because it is simple and versatile.
Are casement windows good for older houses?
Yes. A cottage style casement with smaller panes gives an older home Tudor or Georgian character while using a low-maintenance uPVC frame. If your house originally had sash windows, it is worth comparing both styles at your survey, as sashes may suit a Victorian or Georgian front better.
Casement or sash: which should I choose?
Casements open outwards on a hinge, give clear views and suit most house types. Sash windows slide up and down and suit period homes, especially Victorian and Georgian terraces. Casements also need space outside to open, so for windows over a path, a sash or tilt and turn can work better.
Can casement windows have restrictors?
Yes. Opening restrictors are available, which let you open the window a little for air while stopping it swinging wide. They are a sensible choice for upstairs rooms and children's bedrooms. Ask at your survey and we will build them into your quote.
Do casement windows come double glazed?
Yes, all our casements can be double glazed. Two panes with a sealed gap between them keep the room warmer and the inner glass drier. If your main worries are cold rooms, condensation or noise from outside, our double glazed casement windows page explains how the glazing helps.
Are casement windows energy efficient?
Yes. A casement closes firmly against its frame, so it is good at keeping heat indoors and draughts out. With double glazing the room holds its warmth for longer. Your windows are only one part of your home's EPC, so if you want to know where you stand, run our free energy check and see your current rating.
