Aluminium Bifold Windows

The Servery Window

The most popular use of a bifold window is above a kitchen bench that backs onto a deck or an outdoor dining area. Fold the panels away and the bench becomes a bar: plates go out, drinks come in, and whoever is cooking is part of the conversation outside. Our Dannemora project has exactly this, a bifold servery in matt black between the kitchen and an outdoor kitchen with timber bar stools, and it is the window the owners use most.

The same window works anywhere a solid wall of opening glass makes sense: a lounge onto a courtyard, a bedroom onto a balcony, a home office that wants to feel like a verandah in summer.

How NuStyle Bifold Windows Work

• Bottom-rolling panels. The panels run on rollers in the bottom of the frame, so their weight is carried by the sill.
• A proper sill. A bifold window needs a sill for weathertightness, so every one we make has one.
• Fold left, right or both. Panels stack to one side or split to both, and one panel can be hinged to open on its own for everyday ventilation.
• Double or single glazing, with Low E or laminated glass available.
• Sleek low-profile handles and multipoint locking so the folded wall is as secure as a fixed one. See the hardware page.

Bifold Window or Bifold Door?

Choose a window when the opening sits above a bench, a half-wall or a balustrade, so the sill stays at bench height. Choose a bifold door when you want to walk through the opening. The two are built on the same system and are often used together on one wall, a bifold door from the dining room beside a bifold window from the kitchen, so the whole side of the house opens up.

Colours, Frames and Installation

Bifold windows come in all our standard Dulux colours and the anodised finishes on the colours page, in standard or thermally broken frames. They are made to measure in our Papatoetoe factory and installed by our own team, who set the head and sill dead level so the panels fold and lock without fuss. A bifold window is a larger opening than most windows, so on an existing house we check the lintel during the measure; a new or wider opening in a house of up to two storeys is generally covered by the Building Act's exemption for window and door work, but it must still meet the Building Code, which means a properly sized lintel.
