Aluminium Windows
Thermal-break aluminium windows combine a slim, strong frame with the insulation of a system window. A polyamide thermal break between the inner and outer frame cuts heat loss and condensation, while multi-chamber profiles and quality gaskets keep out wind, rain and noise. OCALWA supplies casement and sliding aluminium windows at container scale, direct from verified factories, in any RAL colour with OEM options.
Slim frames, system performance
Casement windows hinge at the side and open outward or inward for full ventilation and easy cleaning; sliding windows glide horizontally to save space with no swing. Both use thermal-break profiles, double or triple glazing, and multi-point locking for security and a tight weather seal.
Frames are powder-coated in any RAL colour, wood-grain or anodised finish, and glazing can be tuned for solar control, low-E, laminated safety or acoustic performance to suit hot, humid, coastal or high-altitude LATAM projects.

Why choose aluminium windows
Warm, quiet, efficient
The thermal break and insulated glazing cut heat transfer, condensation and outside noise, lowering energy use in hot and cold climates alike.
Slim, strong and durable
Aluminium carries larger glass on thinner frames than uPVC and will not rot, warp or corrode, ideal for coastal and tropical projects.
Made to your project
Sizes, opening styles, glazing and any RAL colour are made to order, with smart and system-window grades available.
Container-scale supply
We consolidate mixed styles and sizes into full-container loads from verified factories, with export documentation handled by OCALWA.

Aluminium windows · frequently asked questions
A polyamide strip separates the inside and outside of the aluminium frame so heat and cold cannot pass straight through the metal. It cuts energy loss and stops condensation forming on the frame, which plain aluminium suffers from.
Casement windows seal tightest and give full opening for ventilation, but need swing space. Sliding windows save space and are easy to operate over sinks or on balconies. Both are available in the same thermal-break system.
Frames come in any RAL powder-coat colour plus wood-grain and anodised finishes. Glazing can be double or triple, Low-E for solar control, laminated for safety, or acoustic, chosen to suit the climate and use.
