Origin Window

A quick guide to casement, tilt & turn, sliding sash, reversible, fixed, parallel and curtain wall windows

Whether you are choosing windows for a new build, extension or renovation, one of the first things you will need to decide on is the type of window. Below is a quick guide to the different types of window on the market.

Casement Windows

This is the most common type of window used in UK housing. The windows are usually divided into several sections or ‘inserts’ that open outwards. Opening windows are usually hinged to the side or the top. Casement windows can be modern or traditional in appearance.

Tilt/Turn windows

This is a type of window most associated with Continental Europe. Typically, these inward opening windows are designed with a smaller number of large inserts and tend to look more modern. Turn the handle through 90° and the window tilts inwards on the bottom hinge; turn the handle through 180° and the window swings inwards on its side hinge.

Sliding Sash Windows

Used widely in Georgian, Victorian and Edwardian period homes, the style of the original box sash window remains popular, particularly in the more traditional properties in the UK. There are now a number of more modern interpretations of the original:

  • In keeping with the original design, weights are suspended on cords and housed in the box outer frames. The weights counterbalance the weight of the opening window.
  • A more modern alternative is available where the weights are replaced with a spring balance instead. This has the advantage of reducing the thickness of the outer frame.

Fully Reversible Windows

Primarily designed for flats, these windows usually have a simple design and can be fully rotated for easy cleaning from the inside.


Fixed Light Windows

A fixed light or fixed window can be made to complement any of the opening window types described in this guide. They can be very large as the maximum size is not limited by the weight a hinge can carry.



Parallel opening windows

Seldom used in domestic situations, the parallel opening window is most commonly seen as part of a curtain wall facade. The window is mounted on ‘scissor hinges’ that enable the window to open by moving outwards on all sides, keeping in the same plane as the surrounding wall.

Curtain wall

Curtain wall is a glass facade most often associated with commercial buildings like office blocks. On a smaller scale, curtain wall can have some very striking applications in domestic properties, particularly in creating a double height atrium or stairwell.

"The whole process has been excellent - I really appreciate the patience you've taken on what is a huge expenditure for a passion project, working with total amateurs! You've always taken the time to answer questions, explain options and crucially, make recommendations when nativity/inexperience clouds our judgement. A real skill and something I personally have really appreciated as I feel confident that we now have windows and doors that complement our house, design and style. Without that level of consultative engagement and relationship I'm confident I would have overlooked details and made a substandard decision. Thank you!"

Mrs Trestain, Padstow

"Just a quick note of thanks to the whole team for our fab windows and doors, we are delighted with both the product and also with the whole fitting process. The lads were brilliant (it's not often you get trades in the house who leave it cleaner at the end of the day than when they arrive in the morning!!) and just quietly got on with the job. Thank you again"

Mr & Mrs Leonard, Exeter

"The pocket sliding door and gable look amazing, it’s an impressive bit of kit and it’s a revelation to be able to open the space up! I have to say we’ve been very impressed with all your teams positivity, professionalism and workmanship, from start to finish - so a big thank you…"

Mr & Mrs Miller, Exmouth

"I wanted to just send my thanks and appreciation. We had an install approx. 6 years ago including some bi-fold doors which in recent weeks appeared to have dropped and became very difficult to lock. I called the office on Monday and a lady took my details and quickly called me back suggesting you had an engineer locally the following day. He arrived and was extremely polite and efficient and diagnosed a broken hinge. He went back to the depot collected the replacement part, then returned to Budleigh and completed the repair. We really appreciate the speed and efficiency with which you dealt with the issue and the ease from a customer perspective. "

Mr Ashby, Budleigh Salterton

"I just wanted to say thank you for the excellent service you have provided in the planning, removal & installation of our beautiful new windows and doors. We were completely amazed & delighted at the speed of which the installation took place and the hard work put in by the installation team. They worked very efficiently and communicated with me at ease through the week so I knew their plans with each room for installation. All the windows & door look great and we have already had lots of compliments. "

Mrs Oakes-Ash, Exmouth

"We would like to thank everyone at Aspect Windows for the fantastic service that we have received on our project. From start to finish, you have been so professional and we are totally thrilled with our sliding doors and our side door. We would not hesitate to recommend you to anyone thinking of undergoing a similar project."

Mrs Moores, Templecombe

"We would just like to say how excellent the service has been from Aspect Windows from beginning to end. The salesman could not have been more helpful, we felt completely unhurried and un-pressured. The fitter was also extremely good, he was neat, careful and very respectful of our property as well as being very sociable and polite. Congratulations Aspect Windows on a really good job I wish everything in life could be so straightforward!"
