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 50 miles 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 style is particularly well suited to a range of situations.
For upper floors in flats and apartments, the inward-opening sash stays inside the property rather than projecting over a balcony or neighbouring space. The same is useful where an opening faces a busy pavement or sits close to a boundary.
The tilt position allows controlled ventilation without fully opening the sash. Where there is a risk of falling from height, suitable opening limiters or guarding may still be required. The full turn position can also provide an emergency escape opening where the size and configuration meet the relevant egress requirements.
Because the sash opens inwards, the outside of the glass can be reached from inside the property. In the turn position, you can clean it without using ladders or scaffolding. This is particularly useful in flats and apartments 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.
They have two opening options controlled by a single handle. In the tilt position, the top of the sash opens inwards for controlled ventilation. In the turn position, it opens inwards like a casement, giving full access for cleaning, ventilation and everyday use.
Prices depend on the frame material, size, glazing specification, colour and hardware options. As a guide, fitted uPVC versions often cost around £600 to £1,000, while aluminium versions can cost around £1,000 to £1,800. They usually cost more than standard casement designs because the dual-function mechanism is more complex.
Yes. Modern designs 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 or triple glazing, Low-E glass and insulated frames, they can improve comfort and thermal performance throughout the home.
Yes. The inward-opening turn position allows the outside of the glass to be cleaned from inside the property, which is particularly useful on upper floors and can reduce the need for ladders or access equipment.
They can provide good security when fitted with multi-point locking, robust hinges, internally beaded glazing and suitable handles. The tilt position also allows ventilation without fully opening the sash.
They can be suitable for family homes because the tilt position allows ventilation without fully opening the sash. Where child safety is a concern, suitable restrictors or lockable handles should also be considered.
Yes. They can help reduce outside noise when 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 generally the more affordable option. Multi-chamber profiles deliver good thermal performance, while coloured or foil-wrapped finishes require little maintenance. Modern uPVC profiles can accommodate the more complex hardware required for dual-function operation.
Our uPVC range uses profiles engineered specifically for tilt and turn operation, with internally-beaded double glazing as standard, multi-point locking, and a wide range of colours available. Wood-grain foils give a timber-style appearance for properties wanting two-way opening function with a more traditional look.
Typical fitted prices range from £600 to £1,000 depending on size, glazing spec and colour. The price sits above uPVC casement equivalents because of the more complex dual-function hardware.
Aluminium frames offer slim sightlines and a contemporary aesthetic. The strength of aluminium can support larger sash sizes while keeping the visible frame relatively slim, which suits new builds and modern renovations where a larger glass area is preferred.
The thermal break in modern aluminium profiles helps reduce thermal bridging. Powder-coated finishes are durable and require little maintenance. Anthracite grey, matt black and warm white are popular contemporary colour choices.
Typical fitted prices range from £1,000 to £1,800.
Several specific applications make dual-function designs a practical 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 can benefit from tilt and turn designs where outward-opening casements would encroach on the surrounding space. Modern properties wanting contemporary slim sightlines often specify aluminium dual-function frames 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 can include multi-point locking, internally-beaded glazing and secured hinge hardware. PAS 24 certification is available on selected configurations where an enhanced security specification is required. Secured by Design accredited options may also be available on selected systems.
The concealed hardware on many two-way opening designs is less accessible from outside than the exposed friction stays found on traditional casement designs.
Replacement installations 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 50 miles radius of our Rushden showroom, covering Northampton, Bedford, Milton Keynes, Kettering, Cambridge, Peterborough, Rugby, Hemel Hempstead and surrounding towns.
Qualifying replacement installations are registered through FENSA, with the certification paperwork supplied after completion. Our team handles the survey, removal of the old units, fitting of the new frames including the more complex tilt and turn hardware setup, weather sealing and final checks, 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.
