Why choose this system?

The dense surface of greenEvolution curve is easy to maintain and supports long-term durability. It is designed to withstand weather exposure and everyday wear.

Compatibility with glazing up to 48 mm provides flexibility to choose double or triple glazing for the project’s thermal and acoustic needs.

The system offers a broad range of personalisation options, including standard colours and aluminium cladding where available, making it adaptable to different architectural styles.

Quality, recyclable uPVC is another advantage. Material recovery through a closed recycling loop helps keep resources in use beyond the original product’s service life.

Substantial steel reinforcement provides stability and reliable operation, allowing larger window elements within the specified size and weight limits.

Salamander greenEvolution curve is a versatile option for projects seeking technical performance, design choice, comfort, security and energy efficiency.
