Alitherm 800


Alitherm 800 is designed for projects that demand the highest quality aluminium window. All profiles feature extended, chambered polyamide thermal breaks allowing Alitherm 800 to achieve excellent thermal performance.


This versatile range of profiles can provide many solutions for residential and light commercial applications. It can create traditional casement windows inspired by the elegance and styling of timber products, or contemporary style windows designed for modern homes or offices.


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.
