The Collection
Each Soliss system is engineered around a single conviction — that the frame should serve the view, not compete with it. Made from thermally broken aluminium, finished by hand at our atelier, and installed by a team trained on the systems they fit.
Slimline Sliding System
Glass that disappears, view that doesn't.
Floor-to-ceiling slimline sliding doors with a 23 mm centre sightline. Built for large openings where the architecture is the view — and the frame should not interrupt it.
Slimline Sliding System
A quiet doorway into the garden.
Slimline sliding door with a 28 mm sightline — engineered for unbroken sightlines between living space and garden. Thermally broken aluminium frame with a low, near-flush threshold.
Slimline Sliding System
Effortless on the hand. Honest on the eye.
Our slimmest sliding section — a 15 mm sightline lift-and-slide door engineered for terraces and indoor–outdoor rooms where the eye should meet glass, not metal.
Casement Window
The window, refined down to its hinges.
A precision-milled aluminium casement window with concealed hinges. Designed for daily use over decades — not seasons.
Casement Door / Tall Window
An open door to the horizon.
A taller, heavier casement system for balconies, terraces and rooflines — same precision hinge platform as the G8, scaled for full-height openings.
Bifold Sliding-Folding Door
Open the whole wall — without losing it.
Multi-panel folding wall that stacks flush into a side pocket. The Sliding Folding system turns an entire wall into an opening and back again in a single stroke.
Bespoke Curved Slider
Drawn by the room. Built by the atelier.
A curved-track sliding system, drawn and engineered to the specific radius of the building. Made-to-design — there is no catalogue page, only your plans and our shop floor.
Premium uPVC Sections
Quiet performance. Honest finish.
Premium uPVC sections engineered for thermal comfort and low-maintenance living. Available in white, cream and foiled woodgrain finishes — paired with the same multi-point locking platform as our aluminium systems.
Multi-mode Casement Window
One sash. Three rooms it can be.
A single sash that closes flush, tilts inward for trickle ventilation, or fully turns open for cleaning and airflow. The default European window — engineered on our 78 mm aluminium frame.
Heritage Grid Door & Window
An old shape, drawn on a new line.
Slim aluminium mullions arranged in a Georgian grid — the proportion of a traditional steel-frame door, built in thermally broken aluminium with modern weather sealing. Fixed sidelights and matching transoms available.
System aluminium · eight engineered benefits
Every Soliss system aluminium frame is engineered against the same eight benchmarks — the small details that decide whether a window simply closes, or actually performs for the next twenty years.
Multi-chamber sections and acoustic gaskets that hush a busy street to a hum.
Triple-lip seals and brush gaskets keep airborne grit on the outside of your home.
Tested to Class 4 air permeability — no draughts, no whistling sashes, no leaks.
Class 9A weather sealing with concealed drainage that handles monsoon-grade rainfall.
Espagnolette gearing engages locking points around the entire frame, not just at the handle.
Polyamide insulators inside every aluminium section — keeping heat outside in summer and inside in winter.
Near-flat sills (as low as 18 mm) for seamless indoor–outdoor flow and a barrier-free home.
Anodised aluminium and uPVC sections that never need painting, sanding or sealing — wipe with a damp cloth, that's it.
The Atelier
Soliss Industries was founded by a small team of engineers and fabricators who believed modern fenestration had drifted from craft toward catalogue. We design every system in our atelier, prototype it on our own factory floor, and refuse to ship anything we wouldn't install in our own homes.
We work directly with architects, builders and homeowners — no resellers, no distance between design and delivery. The systems on this page are the entirety of what we make. We'd rather perfect four than ship forty.
