Bi-fold Doors For South Island Homes

Aluminium Bi-fold doors are hugely popular in New Zealand, they allow for a dramatic wide opening offering unrestricted access to outdoor areas that Kiwis love, especially when combined with sliding windows or bi-fold windows. They enable you to open up your living and family areas to give level access to decks or patios increasing your living space. The price of bi-fold doors makes them an affordable option.

Altherm aluminium bi-fold doors easily cope with a large opening span with panels that glide easily along the bottom track. All bi-fold doors are available in double glazing and come in a number of different door combinations to suit your home. Stacking doors open neatly to each side, or, for unobstructed access, choose Altherm’s lay-back bi-fold doors swing back against adjoining walls, keeping the outdoor space clear for entertaining and playing children.

Bi-fold Doors: Versatility and Style for Your Home


Bi-fold doors are an excellent choice for homeowners who want to blend indoor and outdoor spaces seamlessly. Their design offers a wide opening that maximises light and airflow, making them ideal for entertaining, relaxing, or simply enjoying the outdoors. When combined with other window styles, such as sliding or bi-fold windows, they create a harmonious look throughout your home.

One of the standout features of aluminium bi-fold doors is their flexibility. They are available in various configurations, allowing you to choose the perfect design for your needs. Whether you prefer stacking doors that fold neatly to the side or lay-back bi-fold doors that swing against the wall, you’ll find an option that suits your lifestyle.

Double glazing adds another layer of practicality to bi-fold doors, improving thermal efficiency and reducing energy costs. The durable Altherm aluminium frames and smooth bottom tracks ensure years of reliable performance, even in areas with frequent use.

These doors are also highly customisable, with a wide selection of colours, finishes, and hardware to match your home’s aesthetic. Whether you’re building new or renovating, bi-fold doors offer an affordable, stylish, and functional solution to enhance your living space.
