Aluminium Windows

Slim, thermally-broken aluminium window systems engineered to disappear into the view while carrying real structural load — from sliding and casement to tilt-and-turn and fixed formats.

Aluminium window frame with a garden view
Aluminium Series

Frames narrow enough to disappear into the view.

Fabricated from 6063-T5 aluminium alloy and powder-coated for long-term finish retention, our window range spans slim-line casement sashes to wide sliding and fixed-glass formats — each engineered to hold its shape under load without adding bulk to the frame.

A polyamide thermal break runs through the slim-line and minimal-frame systems to hold indoor comfort while keeping sightlines as narrow as the opening allows.

Why This System

Built to perform, not just look good.

Minimal Sightlines

Narrow frame profiles maximise glass area and view.

Structural Strength

Engineered aluminium alloy rated for high wind load, no steel reinforcement needed.

Thermally Broken

Polyamide break reduces heat and cold transfer through the frame.

Corrosion Resistant

Powder coat finish holds up to coastal and urban air.

Custom Finishes

Any RAL colour or anodized finish to match the facade.

Smooth Operation

Sealed rollers and multi-point hardware keep every sash gliding freely for years.
