Ultimately ALTI

Welcome to the world of Alti. First introduced over a decade ago, ALTI was the pioneer in composite (aluminium & timber) windows and doors, and continues to be the market leader.

The ALTI range commences with a base model, high-performance composite joinery suite which can be built on with a comprehensive set of additional specifications, where your choice will depend on your design and budgetary needs.

ALTI's versatility means it can be used in a variety of applications, including renovations and additions where it is important to retain the character of the home. In new homes ALTI can be used in a number of ways. You can choose to install ALTI throughout your entire house, or you can mix 'n match with our standard aluminium joinery by completing, for example, the living area only in ALTI.
