uPVC Performance. Aluminium Protection

High-End Look and Modern Aesthetics

A sleek aluminium exterior with a wide range of RAL colours and premium finishes provides outstanding design flexibility for modern architecture.

Extreme Weather Resistance

Aluminium enhances the window’s durability under harsh environmental conditions. It offers superior protection against intense sun, heavy rain and wind.

Increased Structural Stability

Thanks to the rigid aluminium exterior, these windows are particularly suited for large glazing elements and modern façade designs. They maintain form and function large formats, without compromising performance.

Extended Lifespan and Sustainability

Aluminium-clad uPVC windows are extremely long-lasting and 100% recyclable. The combination of two highly durable materials ensures a lower carbon footprint over the product’s lifecycle.

Customisation and Colour Variety

While the interior uPVC offers warmth and comfort, the external aluminium shell allows extensive customisation. Choose from the full RAL range or premium effect colours to meet even the most demanding design requirements.

Enhanced Thermal & Acoustic Performance

The combination of a multi-chamber uPVC profile and an aluminium exterior delivers excellent thermal insulation while maintaining high structural performance. It helps reduce energy consumption, improves indoor comfort, and provides effective sound insulation for quieter living spaces.
