Modern New Zealand homes are increasingly designed around:

• Open-plan living
• Natural light
• Outdoor entertainment areas
• Strong indoor-outdoor connections

As a result, large aluminium doors have become one of the most important architectural features in contemporary homes.

Two of the most popular options are:

• Aluminium sliding doors
• Aluminium bifold doors

Both provide excellent ways to connect indoor and outdoor spaces, but they offer different advantages.

Many homeowners ask:

“Should I choose aluminium sliding doors or bifold doors for my NZ home?”

The answer depends on:

• Home design
• Opening size
• Lifestyle needs
• Budget
• Architectural preference

MEICHEN Windows&Doors specialises in aluminium windows and doors, providing sliding door and bifold door solutions designed for New Zealand residential and architectural projects.

What Are Aluminium Sliding Doors?

Aluminium sliding doors operate by moving horizontally along a track.

A typical system includes:

• Aluminium frames
• Large glass panels

When opened, one or more panels slide behind each other.

Sliding doors are widely used for:

• Living rooms

What Are Aluminium Bifold Doors?

Aluminium bifold doors use multiple panels connected by hinges.

When opened, the panels fold and stack together.

A bifold system creates a large opening between:

Indoor spaces

and

Outdoor areas

They are commonly used in:

• Entertainment areas
• Kitchens
• Living rooms
• Luxury homes
