Tilt & Turn Window Features

Scandinavian design & performance

Clean Scandinavian design and the ability to open inwards for easy cleaning make these the perfect choice for 3 story contemporary homes, flats and apartments.

Our tilt and turn windows are Secured By Design and Part Q compliant with exceptional airtightness and Uw values from 0.8W/m²K, perfect for EnerPHit (Passivhaus retrofit) projects and new build low energy homes.

Make an impact

The inward opening design of our timber tilt and turn windows mean they are great for not only designing something visually stunning but give excellent ventilation and allow for external shading and shutters to be used.

Unique Features

The concealed hinge system, concealed trickle vents and our unique external timber drainage design mean that we don’t have aluminium or plastic bottom beads that detract from the clean lines of the frames. This unique detail means that the design is completely manufactured from timber on the outside.

Totally bespoke

Totally bespoke sizes and design. Opening windows can be supplied up to 1.5 metres wide and 2.4 metres high, with fixed lights available up to 2.5 metres wide by 2.4 metres high.

Add a splash of colour

Every tilt and turn window is beautifully factory finished using the most environmentally friendly water-based paint or stain. Choose from any RAL Classic, RAL Design, NCS and BS colour charts or match to Farrow & Ball, Earthborn or Fired Earth colour collections.

With single or dual colour options you can create the perfect match to the exterior facade and interior decor of the property.

Mock Sash

Tilt and turn windows are also often used to imitate sash windows, particularly when escape access is required for compliance with building regulations and the clear opening cannot be achieved with sash windows. Customise with contemporary or traditional mouldings and bars.

Specialist glazing

Solar control ultra-clear glazing can be incorporated to neutralise the effects of the sun and can aid in avoiding overheating in large expanses of glazing.

For a splash of colour you can also add a coloured tint; choose from Blue, Green and Bronze colours. Perfect for low energy homes with centre pane Ug values from 0.5W/m²K.

Handles & Locks

Our timber tilt and turn windows come with our contemporary connoisseur handle that is available in a choice of 5 different colours Polished Chrome, Satin Chrome, Brass Plated, Black and White.

Obscure Glazing

Glazing is an important design element for any project and can make all the difference when creating a feature window or door. A variety of obscure glazing patterns are available with different designs offering varying privacy levels (rated 1-5 with 5 being the highest level).
