Opening Functions

Our windows and doors are available in a range of variable opening functions. Listed below are all of the opening styles that Rationel offer. Certain products only offer certain opening functions, please enquire to confirm which functions are offered for the product you are interested in.

Windows

Fixed light windows

Fixed windows are perfect for maximising the amount of light inside your home and bringing out the beauty in the scenery around you. The glass of a fixed window is inserted directly into the frame, meaning their function is not to open, but to let more natural light and warmth into your room. With a larger area of glazing and slimmer window frame, fixed windows are ideal for properties based in the countryside.

Advantages of fixed windows

1. Highly energy efficient
2. Maximum use of light
3. Optimal views of your surroundings

Topguided window

Top guided windows are simple, elegant and user-friendly.  A must-have for fans of modern and minimalist aesthetics, the opening function of a Rationel top-guided window is controlled by tracks and slides, with adjustable friction ironmongery allowing for nearly unlimited opening positions.

Advantages of top guided windows

1. Suitable for all rooms
2. Easy, seamless opening function
3. Provides effective ventilation when open, both above and below the sash
4. No visible external hinges

Sidehung window

Our side hung windows boast an outward opening function with a simple and stylish design, making them safe, secure and a highly popular choice among homeowners.

Rationel side-hung windows come complete with a handle-controlled friction brake*, allowing them to be fixed in any open position. They also make great access windows or “escape windows”, and are a strong choice for those looking to install an emergency exit in a commercial or industrial property.

Advantages of side hung windows

2. Simple, stylish design
3. Safe, secure, and suitable escape windows

Topswing window

Our top swing windows are popular among homeowners who see ease of maintenance and high levels of child safety as their main priorities.  Rationel top swing windows have a cleverly designed mechanism which allows the sash to turn almost 180 degrees which makes the window reversible, meaning the glass can quickly and easily be cleaned from the inside.

Advantages of top swing windows

1. Multi-functional
2. Suitable for multi-storey buildings
3. Easy to clean
4. Comes with child-proof opening limiter

Sideguided window

Side guided windows are controlled by tracks and slides, they are ideal for use in multi-story structures where cleaning can only be achieved from the inside of the building.  Our side guided windows come with no visible external hinges and an adjustable sash which moves towards the middle when opened, creating an opening that allows the glass to be cleaned from the inside.

Advantages of side guided windows

1. Can be cleaned from the inside
2. Simple and seamless opening
3. Good ventilation
4. Minimalist design

Tilt & turn window

Rationel tilt and turn windows can function in two ways. The tilt function opens the top of the sash by approximately 10cm, allowing fresh air to ventilate the room.  The turning function allows for them to be opened inwardly, hinging from the side.  As a result of these functions, tilt and turn windows can easily be cleaned from the inside, and are perfectly suited as “escape windows” or emergency exits.

Advantages of tilt and turn windows

1. Multi-functional window, doubles well as an escape window or emergency exit
2. Suitable for multi-storey buildings
3. Easy to clean
