Slide into summer with ultra slim style: Why our aïr 400SS Sliding Door is the smart upgrade for your home
It’s official, sliding aluminium doors are having a moment. Whether you’re planning an extension, replacing old patio doors or building your dream home from scratch, large sliding glass doors are now the go-to feature for creating bright, modern living spaces.
But it’s not just a trend. It’s a smarter way to upgrade your home, both in looks and in lifestyle.
Homeowners are thinking differently
At aïr, we’ve noticed something happening in the market, and it’s backed up by the latest industry research. There’s a clear shift in how people are choosing to invest in their homes. For some homeowners, those who’ve built up equity and are looking to enhance the spaces they love, it’s about futureproofing: choosing high-performing, design-led upgrades that add lasting value.
Others, those who may be working with tighter budgets, are choosing well-considered improvements that offer real returns – more light, more usable space, and better energy performance. Whichever category you fall into, this is where sliding aluminium doors like the aïr 400SS Minimal Frame Sliding Door comes in.
Ultra slim, effortless style
Our next generation aïr 400SS is all about ultra slim sliding doors that deliver maximum glass and minimum frame. With sightlines as slim as 20mm, the design creates a seamless connection between indoors and outdoors, perfect for summer entertaining, morning coffee with a view, or just soaking up more natural light all year round.
Whether you’re replacing French doors or building a new open-plan space, our aïr 400SS Minimal Frame Sliding Door gives you that clean, architectural look that elevates any home.
More glass. Less hassle.
One of the biggest benefits of choosing sliding aluminium doors over bifold doors can be simplicity. While bifolds stack, sliding doors glide, meaning you keep your views, even when the doors are open. And with our aïr 400SS Minimal Frame Sliding Door, you get more than just good looks:
Plus, our latest update features site-bonded glazing, making installation smoother and more efficient, great news if you’re on a tight renovation schedule.

Investing in large sliding glass doors isn’t just about making a statement, it’s about making your home more efficient, more comfortable, and more connected to nature.
