This window style is a modern design with two operating modes controlled by a single handle. Turn the handle to one position and the window tilts inward from the top, giving secure ventilation without the sash opening fully. Turn the handle further and the window opens inward like a casement, giving full access and easy cleaning of the outside glass from inside.
We supply and fit tilt and turn windows in Northamptonshire within an 80 km radius of our Rushden showroom, with uPVC and aluminium options available in the full RAL colour palette. Best for contemporary properties, upper-floor installations and rooms where the dual operating function adds practical value.
A two-way opening window has a single sash that operates in two modes. The tilt position opens the window inward from the top by around 15 to 20 degrees, allowing controlled ventilation while the sash remains secured at the bottom. The turn position opens the window inward fully like a casement, swinging the sash into the room for unrestricted access.
The dual operation comes from a sophisticated multi-point locking mechanism. When the handle is in the closed position, the locks engage at multiple points around the frame perimeter, creating a tight seal and full security. When the handle moves to tilt, only the top of the sash is released, with the bottom hinges keeping the sash captive. When the handle moves to turn, all the locking points except the side hinges release, allowing the sash to swing inward.
The tilt mode is the most-used position for daily ventilation. The turn mode is used for cleaning, emergency egress and full ventilation in summer.
This window style is particularly well suited to a range of situations.
For upper-floor windows in flats and apartments, the inward-opening sash doesn’t encroach on anything outside the building, where outward-opening casement windows would interfere with neighbouring properties or balconies. For windows facing busy pavements or close to boundaries, the inward action keeps the open sash within the property.
The tilt position gives secure ventilation in homes with young children, since the limited opening angle prevents the sash from opening enough to allow a child through. The internally-secured sash also makes tilt and turn windows the preferred fire-escape window in upper-floor installations because the full turn opening clears the entire frame for egress.
The inward-opening design makes cleaning upper-floor windows simple and convenient from inside the property. The turn position swings the sash inward, letting you clean the outside glass without needing ladders or scaffolding. This is the main reason dual-opening windows are common in apartments and flats above ground floor.
The dual-function design delivers practical advantages that casement and sash windows can’t match.
The tilt position gives controlled background ventilation throughout the day. The narrow opening angle prevents draughts in winter while letting fresh air circulate. The turn position opens the window fully when you want maximum airflow in summer.
The inward-opening turn position lets you clean both sides of the glass from inside the property. This is the single biggest practical advantage for upper-floor windows where outside access is difficult or unsafe.
The tilt position locks the bottom of the sash to the frame while only the top opens. The limited opening angle and the secured bottom edge make forced entry significantly harder than with a fully-open casement window. The closed-position multi-point locking matches the security of modern casement and sash windows.
The tilt mode opens the window enough for ventilation but not enough for a child to climb through. Households with young children benefit from the controlled-opening function compared with casement windows that open fully even at partial handle positions.
Modern tilt and turn windows achieve U-values from 1.2 W/m²K with double glazing and from 0.8 W/m²K with triple glazing. The multi-point locking compresses the sash firmly against the perimeter seals, eliminating draughts and reducing heat loss through air infiltration.
Tilt and turn windows are modern windows with two opening options controlled by a single handle. In the tilt position, the top of the window opens inward for secure, controlled ventilation. In the turn position, the sash opens inward like a casement window, giving full access for cleaning, ventilation and everyday use.
Two-way opening prices depend on the frame material, size, glazing specification, colour and hardware options. As a guide, fitted uPVC dual-function windows often cost around £600 to £1,000 per window, while aluminium tilt and turn windows can cost around £1,000 to £1,800. They usually cost more than standard casement windows because the dual-function mechanism is more complex.
Yes. Modern tilt and turn windows can be very energy efficient because the sash closes firmly against the frame, helping to reduce draughts and heat loss. When combined with quality double glazing or triple glazing, Low-E glass and insulated frames, they can improve comfort and thermal performance throughout the home.
Yes. Dual-opening windows are usually easier to clean than outward-opening casement windows, especially on upper floors. The inward-opening turn position allows you to clean the outside of the glass from inside the property, which can reduce the need for ladders or access equipment.
Yes. This window style can provide strong security when fitted with multi-point locking, robust hinges, internally beaded glazing and high-quality handles. The tilt position also allows ventilation while limiting the opening, which can be useful when you want fresh air without leaving the window fully open.
Yes. Tilt and turn windows can be a good choice for family homes because the tilt position provides ventilation while keeping the opening restricted. This makes them useful for bedrooms, upper floors and apartments. For extra peace of mind, additional safety restrictors or lockable handles may also be fitted.
Yes. Tilt and turn windows can help reduce outside noise when they are fitted with quality sealed glazing units and effective weather seals. Acoustic laminated glass or upgraded glazing options may provide further noise reduction for homes near busy roads, schools, rail lines or flight paths.

This window style is available in two main frame materials for the UK market.
uPVC tilt and turn windows are the most affordable option. Multi-chamber profiles deliver good thermal performance and the powder-coated or laminated finish lasts decades without maintenance. The strength of modern uPVC handles the more complex hardware that dual-function operation requires.
Our uPVC dual-opening windows are built on profiles engineered specifically for tilt and turn operation, with internally-beaded double glazing as standard, multi-point hook locking, and the full RAL colour palette available. Wood-grain foils give the timber appearance for properties wanting two-way opening function with a traditional aesthetic.
uPVC tilt and turn windows typically cost £600 to £1,000 per window fitted depending on size, glazing spec and colour. The price sits above uPVC casement equivalents because of the more complex dual-function hardware.
Aluminium frames deliver the slimmest sightlines and the most contemporary aesthetic. The strength of aluminium handles larger sash sizes than uPVC can while keeping the visible frame thickness minimal, ideal for new builds and modern renovations wanting maximum glass area.
The thermal break in modern aluminium profiles prevents cold-bridging. Powder-coated finishes last 25 years or more without fading. Anthracite grey, matt black and warm white are the most popular contemporary aluminium dual-opening window colours.
Aluminium tilt and turn windows typically cost £1,000 to £1,800 per window fitted.
Several specific applications make dual-function windows the right choice.
Apartments and flats above ground floor benefit from the inward-opening operation and the cleaning convenience. Upper-floor bedrooms in houses get the same cleaning benefit plus the child safety of the controlled tilt position. Bathrooms and kitchens benefit from the controlled ventilation when steam needs venting without leaving a window fully open.
Properties near busy pavements or close to neighbouring boundaries use tilt and turn windows where outward-opening casement windows would encroach on the external environment. Modern properties wanting contemporary slim sightlines often spec aluminium dual-function windows for the architectural look.
The full RAL colour palette is available across the uPVC and aluminium tilt and turn window range. The most-requested colours track contemporary preferences. Anthracite grey leads as the most popular modern colour. Matt black suits properties wanting maximum contrast. Warm white works for contemporary minimalist designs. Traditional cream and Chartwell Green are available for properties wanting desiring heritage colours combined with dual-function.
Dual-colour finishes give you one colour outside (matching the front elevation) and a different one inside (matching the room scheme). Wood-grain foils on uPVC frames provide the character and appearance of timber.
Every tilt and turn window we supply comes with double-glazed sealed units as standard. Modern double glazing delivers good thermal performance and significant noise reduction.
Triple glazed two-way opening windows are popular upgrades because the more complex frame construction handles the additional weight without operational compromise. Triple glazing reduces heat loss by a further 25 to 30% compared with double glazing, with U-values dropping to around 0.8 W/m²K.
Low-E glass is standard across both double and triple glazed units. Soundproof acoustic-laminated glass is available for properties near busy roads or flight paths.
Tilt and turn windows include multi-point hook locking, internally-beaded glazing, secured tilt-position hinges, and PAS 24 doorset certification available across the range. Secured by Design certification is available on aluminium dual-opening windows for the highest residential security spec.
The concealed hardware on most two-way opening designs is harder to interfere with from outside than the exposed friction stays on traditional casement windows.
Replacement windows need to meet the relevant Building Regulations for thermal performance, safety and ventilation. As a FENSA-registered installer, Homeefe supplies the required certification after eligible replacement window installations.
During the survey, we also check background ventilation requirements, including whether trickle vents are needed under Approved Document F. This means the final specification is based not only on frame style and colour, but also on how the room needs to ventilate.
We install tilt and turn windows across Northamptonshire within an 80 km radius of our Rushden showroom, covering Northampton, Bedford, Milton Keynes, Kettering, Cambridge, Peterborough, Rugby, Hemel Hempstead and surrounding towns.
Installation is FENSA-registered with the certification paperwork supplied at handover. Our team handles the survey, removal of the old windows, fitting of the new frames including the more complex tilt and turn hardware setup, weather sealing and final commissioning, with all waste taken away at the end.
uPVC versions usually take around 5 to 7 weeks for delivery and fitting. Aluminium versions usually take around 7 to 9 weeks for delivery and fitting. Installation is typically a one or two day job for a full-house replacement, with each dual-opening window taking slightly longer than a casement equivalent because of the more complex hardware setup and commissioning.
The dual-operation function is best appreciated in person. Our Rushden showroom has full-size tilt and turn window samples in uPVC and aluminium in all the popular colours, so you can try the dual-action mechanism for yourself and compare its operation with casement and sash alternatives.
