Suspension track technology removes friction from sliding windows entirely. Slide a 2 m sash with two fingers, hear nothing, and seal out the weather better than any traditional window on the market.
Suspension sliding windows — also marketed as floating sliding windows — are a type of window that combines suspension technology with a sliding design. The sash hangs from the top track on stainless steel bearings, eliminating the metal-on-metal scrape of a standard slider.
Widely used in modern homes and apartments, they offer a perfect blend of aesthetics and functionality. For large balconies and terraces, the suspension system allows expansive views and larger openings, maximising natural light and fresh air indoors.
A standard sliding window wears out from the day it’s installed. The suspension design eliminates the root cause.
Sash hangs from the top track — minimal friction, no bottom-rail contact.
Precision EPDM seals + suspended sash = tighter than any standard slider.
No metal-on-metal scrape — ideal for bedrooms, studies, apartments.
Mechanical components rated for decades of daily residential use.
Slim profile frames and minimal sightlines suit contemporary architecture.
Two-finger sliding even on large sashes. Accessibility-friendly.
The Melbourne Sunroom team helps you choose the right suspension sliding window based on the number of tracks, functional features and installation requirements — to suit different rooms, scenarios and needs.
Every window we install complies with AS 2047, AS 1170 and AS 1288 — the Australian Standards for window installation, structural loading and glazing.
A standard sliding window has the sash sitting on the bottom track. Every time you open or close it, metal grinds on metal. Over years, the track wears, the sash sags, the seal degrades, and operation gets heavier.
Suspension flips that on its head — the sash hangs from above on bearings, so the bottom track never wears, the sash never sags, and the seal stays tight for decades.
A clear, stress‑free process from first call to final handover — no surprises.

A floating sliding window — technically called a suspension sliding window — is a window where the sliding sash hangs from the top track rather than sitting on the bottom track. Suspended stainless steel bearings carry the weight, dramatically reducing friction. The result: smoother sliding, quieter operation, tighter sealing, and far longer mechanical life than a standard sliding window.
Yes — typically 30-60% more than a standard aluminium slider of the same size. The premium comes from the suspension hardware, tighter manufacturing tolerances, and longer-lasting sealing systems. For bedrooms, studies, apartments and any window you’ll open daily, most homeowners find the comfort and durability worth the upgrade.
In most cases, yes. The floating sliding window installs into the same opening as a standard sliding window. We measure on-site, manufacture to fit your existing opening, and remove the old window before fitting the new one. No structural work needed for a like-for-like replacement.
Excellent. Because the suspension system maintains a tighter seal than worn standard sliders, they perform better against Melbourne’s wind-driven rain and temperature swings. With a double-glazed IGU upgrade, they’re compatible with 7-star NatHERS energy ratings.
Significantly quieter than a standard slider — both during operation (no metal-on-metal scrape) and against external noise (tighter seal blocks more sound). With laminated IGU glass, acoustic ratings up to Rw 35 are achievable, suitable for homes on busy roads or near train lines.
The suspension mechanism is rated for 50,000+ open/close cycles. With normal residential use, that’s easily 25-30 years of trouble-free operation. The aluminium frame itself outlasts the mechanism. We back our installations with a long-term warranty on frame, hardware and installation workmanship.
Clear, tinted (grey, bronze), Low-E energy-efficient, obscure (for bathrooms or street-facing rooms), laminated security glass, and double-glazed IGU (recommended for Melbourne). Custom combinations on request.
