Product information

Alitherm 700 is an innovative solution for enhanced natural ventilation. The system allows for a balanced, effective airflow whilst maintaining security and safety. The system can also be either a side or top hung casement, or top swing reversible window.

Alitherm profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product and is designed to meet the exacting requirements of Document L 2010.

Alitherm products are available in a choice of standard or non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodised effect finishes.
